A 15 mm bore identifies only the shaft size, not a replaceable Timken bearing. You will be able to verify the full envelope, load and speed data, mounting arrangement, included components, price basis and Delhi stock status before accepting a quotation.
Key takeaways
- Match the full Timken part number, not only the 15 mm bore.
- Check outside diameter, width, load ratings, speed and clearance before ordering.
- Confirm angular-contact direction and mounting arrangement against the machine drawing.
- Compare Delhi quotations for seals, grease, delivery, taxes and warranty terms.
Why a 15 mm bore is not enough to identify the bearing
A 15 mm bore identifies only the shaft-side opening, not the bearing. The exact Timken part number is missing, so you cannot confirm fit against the housing, drawing or original equipment. A 15 mm bore does not distinguish metric from inch-series products, bearing families, or suffix configurations such as seals, shields, clearance and cage design.
| Bearing | Bore × outside diameter × width or height | Practical consequence |
|---|---|---|
| 6202 | 15 × 35 × 11 mm | Deep-groove ball bearing |
| 6302 | 15 × 42 × 13 mm | Different housing and width requirement |
| 30202 | Approximately 15 × 35 × 11.75 mm overall; 11 mm cone, 9.5 mm cup | Tapered-roller geometry with separable cone and cup |
| 30302 | Approximately 15 × 42 × 14.25 mm | Different tapered-roller envelope |
| 32202 | Approximately 15 × 35 × 14.25 mm | Same bore and outside diameter as 30202, but different height and geometry |
6202 cannot replace 6302 solely because both have a 15 mm bore. Likewise, 30202, 30302 and 32202 require comparison of cone and cup geometry, included angle, flange arrangement, effective load centre and preload or endplay.
For a 15 mm Timken industrial bearing for specifications in Delhi, request:
- Exact designation and part number
- Outside diameter, overall width, shoulder dimensions and bearing family
- Precision class, cage code, sealing or shielding code and internal clearance
- Dynamic and static load ratings, limiting speed and whether it is a matched set
Timken bearing dimensions in Delhi must also account for cylindrical-roller, needle-roller, thrust and mounted bearings. Each has different installation methods and radial or axial load rules.
Which missing ratings determine whether the bearing suits the machine
A bearing suits a spindle, pump or gearbox only after its load, speed, temperature and lubrication limits are confirmed. Request the dynamic radial load rating, static radial load rating, axial load capacity, limiting speed, operating temperature range, lubricant type and factory grease fill.
CN means normal internal clearance; it does not establish speed or temperature suitability.
Ask the quotation to state:
- Whether the bearing is open, 2RS or equivalent contact-sealed, or ZZ or equivalent shielded
- Whether grease is factory-filled, including grease name, NLGI consistency and fill quantity
- The exact suffix or manufacturer datasheet, because “both-side sealing” conflicts with a separate “metal shields” field
- Whether the listed clearance is CN or C3, with the manufacturer’s specified value
CN can be unsuitable where high thermal gradients, heavy interference fits or additional internal clearance are present; C3 may suit those conditions, but never assume it without the manufacturer’s specification.
| Construction | Friction and heat | Relubrication behaviour |
|---|---|---|
| Open | Lowest seal friction; lubricant loss or contamination is possible | Requires an external lubrication and contamination-control plan |
| 2RS contact-sealed | Higher friction and heat at speed | Factory grease is retained; relubrication access is limited |
| ZZ metal-shielded | Lower friction than contact seals; shields do not fully seal against contamination | Factory grease is retained; verify the supplier’s limits |
Grease and oil are not interchangeable. Check viscosity, consistency, temperature range, seal compatibility and relubrication interval before changing lubricant; over-greasing raises temperature and reduces speed capability. A search for 15 mm timken bearing price in delhi is incomplete without these ratings.
How to confirm fit, angular-contact direction and mounting arrangement
1. Measure the shaft at several positions along its seat and around its circumference with a micrometer. Measure the housing bore with a bore gauge, check roundness, and record the drawing tolerance.
Request the tolerance class, runout grade, shoulder diameter and shoulder height from the drawing or manufacturer catalogue; these details confirm timken bearing dimensions in delhi beyond a 15 mm bore.
2. Select the fit from the ring’s movement and load. A rotating ring under load generally needs controlled interference; use a light press fit, transition fit or clearance fit only as the design specifies. Give the ring clearance where it must move axially for thermal expansion.
An incorrect press fit can crush internal clearance or make the bearing creep.
3. Confirm the angular-contact direction before installation. Its contact angle carries axial load in one direction, so a single bearing cannot automatically replace a deep-groove ball bearing where axial loads reverse. Ask for the contact-angle orientation and mounting order.
4. For a pair, use DB back-to-back for stiffness and moment load, DF face-to-face where alignment tolerance matters, or DT tandem when axial load acts in one direction. Require the supplier to state whether the pair is matched, its preload class or operating endplay, and its mounting order.
Press on the fitted ring only; pressing through the rolling elements damages the raceways and bearing.
What should be included, separately priced or excluded
The box contents must be explicit: request one complete bearing, a matched angular-contact pair, or a tapered-roller cone-and-cup set. A 30202-style tapered bearing has a separable cone and cup with different part numbers, so the quotation must state whether it covers the complete set, cone only or cup only.
Do not assume these items are included unless the designation or quotation says so:
- Bearing grease
- Shaft oil seal
- Locknut
- Adapter sleeve
- Snap ring
- Housing unit
An integral 2RS contact seal or metal shield is part of the bearing configuration, not a separate shaft seal. A separate oil seal requires shaft diameter, housing bore, seal width, lip material, fluid compatibility and temperature rating.
If grease is supplied, request its name, NLGI consistency, base-oil viscosity, temperature range, fill quantity and compatibility with the lubricant already in the machine.
For a substitute, compare the complete specification:
| Item | Compare | Why it matters |
|---|---|---|
| Boundary dimensions | Bore, outside diameter and width | Confirms physical fit |
| Tapered-roller geometry | Cone and cup geometry, effective load centre and flange arrangement | Changes adjustment and load behaviour |
| Performance | Radial and axial load ratings | A similar size may have different life |
| Adjustment | Preload or endplay | Controls heat, noise and service life |
A substitute matching only bore and outside diameter is not a confirmed replacement.
How to compare Delhi price, availability and supplier quotations
Send the supplier the full designation or drawing, not “15 mm bearing.” Include the required quantity, seal or shield code, internal clearance, accuracy class, matched-set requirement and intended application. This prevents a quote for the wrong suffix or bearing family.
Request each commercial item on its own line:
- Unit price
- GST
- Freight
- Lead time
- Packaging
- Warranty terms
- Payment terms
A 15 mm Timken bearing price in Delhi changes with suffix, order quantity, origin, genuine-versus-counterfeit risk and whether a tapered-roller cone and cup are priced separately. A low unit price is not comparable if another quotation includes GST, freight or both tapered-bearing components.
Require the supplier to identify where the exact part number and quantity are held:
| Status | What it means | Evidence to request |
|---|---|---|
| Delhi stock | Physically available in Delhi | Confirm exact quantity and inspection access |
| Indian warehouse | Held outside Delhi | State warehouse location and dispatch date |
| Import lead time | Not currently in India | State estimated arrival and import basis |
A Timken industrial bearing supplier in Delhi, including Shreeji Industrial Corporation LLP, is useful when the quotation answers these checks rather than naming only a generic bore size.
Before accepting delivery, retain the bearing marking, package label, batch or lot details where available, invoice and certificate documents. Inspect the bore, outside diameter, width, seals or shields and packaging condition against the drawing. Price alone does not establish authenticity.

Frequently asked questions
Does a 15 mm bore identify a Timken industrial bearing?
No. It identifies only the shaft-side opening. You also need the full part number, bearing series, outside diameter, width and suffixes for seals, shields, clearance and cage design.
Which specifications determine whether a 15 mm Timken bearing suits a machine?
Compare the bearing’s outside diameter, width, dynamic and static load ratings, limiting speed, internal clearance, contact angle, seal or shield arrangement and lubrication requirement with the machine design.
How do you confirm angular-contact direction and mounting arrangement?
Check the part drawing and marking for contact angle and direction, then match the bearing arrangement—single, paired back-to-back, face-to-face or tandem—to the shaft loads and the manufacturer’s installation instructions.
What should a Delhi Timken bearing quotation include?
Ask the supplier to state the exact part number, quantity, dimensions, suffixes, country or batch information, price basis, GST, delivery charge, delivery date, seals or grease included, warranty and return terms.
