What are tapered roller bearings? Tapered roller bearings are precision rolling element bearings where the rollers, inner ring (cone), and outer ring (cup) are all tapered — designed so their extensions meet at a common point on the bearing axis. This geometry allows them to simultaneously handle both radial (perpendicular) and axial (thrust) loads. Timken invented the tapered roller bearing in 1898 and remains the world’s leading manufacturer — available in single-row (TS), double-row (TDO/TDI), and multi-row configurations for bore sizes from 15 mm to over 1,200 mm.
Types of Timken Tapered Roller Bearings We Supply
As Gujarat’s authorised Timken bearing dealer, SEPL stocks all four major tapered roller bearing configurations — each engineered for specific load requirements and mounting arrangements.

How to Identify Your Timken Tapered Roller Bearing Number
A tapered roller bearing consists of two separable parts — the cone (inner ring + rollers + cage) and the cup (outer ring). Timken marks each part with its own part number, which is how replacement orders are placed. Understanding this system helps plant maintenance teams reorder correctly without sending bearings for inspection first.
Cone (Inner Ring) Part Number
Marked on a face of the cone. For TS bearings: inner ring face. Example: LM48548 is a cone part number. The cone carries the rollers and cage assembly.
Cup (Outer Ring) Part Number
Marked on a face or the outside diameter of the cup. Example: LM48510 is the matching cup for the cone above. Together: LM48548 / LM48510 is the complete assembly number.

| Mining | Crusher shafts, conveyor head pulleys, tunnel boring | TDO / TDI | Shock load resistance, wide operating spread |
| Plastic & Rubber | Extruder gearboxes, calender rolls | TS / TDO | High axial load from extrusion thrust |
| Paper & Pulp | Dryer cylinder trunnions, press rolls | TDO / TS | Moisture resistance, high-speed capability |
| Automotive & Commercial Vehicles | Wheel hubs, differentials, gearbox countershafts | TS / TSF | Compact design, adjustable preload |
| Crane & Material Handling | Crane travel wheels, hoist drum shafts | TDO / TDI | Combined load from rope tension and weight |
How to Select the Right Tapered Roller Bearing
Selecting the correct tapered roller bearing requires matching the bearing’s rated capacity to your actual application loads. Share these 5 parameters with SEPL’s technical team and we’ll identify the right Timken bearing number — no cost, same-day response for Gujarat customers.
Radial Load (Fr)
Load perpendicular to shaft axis — from belt tension, gear mesh forces, weight
Axial Load (Fa)
Thrust along shaft axis — from helical gears, extruder pressure, bevel gear forces
Operating Speed
RPM at the bearing — determines speed factor and lubrication requirements
Required Life (L10h)
Target bearing life in hours — drives the required dynamic load rating (C90)
Bore / Housing Dia
Shaft diameter and housing bore — sets the bearing series and overall envelope

Frequently Asked Questions — Timken Tapered Roller Bearings
What are tapered roller bearings used for?
Tapered roller bearings are used in applications requiring simultaneous handling of radial and axial (thrust) loads — the most common being industrial gearboxes, vehicle wheel hubs, rolling mill roll necks, cement kiln drives, mining crushers, and heavy conveyors. Their tapered geometry makes them the only bearing type specifically engineered for combined load in a compact single-row configuration.
What is the difference between TS and TDO tapered roller bearings?
A TS (Tapered Single) bearing consists of one cone and one cup — mounted in opposing pairs to handle axial load in one direction. A TDO (Tapered Double Outer) uses one double cup and two cones — providing axial load capacity in both directions and a wider effective bearing spread. TDO is preferred where overturning moments are significant, such as heavy gear drives and mill applications.
What is the price of Timken tapered roller bearings in India?
Timken tapered roller bearing prices in India start from approximately ₹385 for small inch series (TS single-row) and go up based on bore size, series, and configuration. As Gujarat’s authorised Timken distributor, SEPL offers factory-aligned pricing. Contact Sarang Vyas at +91 9624739393 or email sales@santramengineers.com with your bearing number and quantity for an accurate quote.
Can tapered roller bearings handle both radial and thrust loads?
Yes — this is the defining advantage of tapered roller bearings over cylindrical or ball bearings. The tapered geometry of the rollers and raceways means that all contact lines converge at a common apex on the bearing axis, allowing simultaneous load transmission in both radial and axial directions. Under radial load, a reactive axial force is generated that must be counteracted — which is why TS bearings are typically mounted in opposing pairs.
How do I select the right tapered roller bearing for my gearbox?
For gearbox selection, you need the radial load (Fr), axial load (Fa), operating speed (RPM), required L10h life, and shaft bore diameter. SEPL’s technical team performs this calculation using Timken’s engineering tools and recommends the exact bearing number with service factor and lubrication specification — share your gearbox datasheet with us at sales@santramengineers.com for a same-day recommendation.
Are Timken tapered roller bearings available in metric sizes?
Yes. Timken produces tapered roller bearings in both inch and metric series conforming to ISO and ANSI/ABMA standards. The metric range covers bore sizes from approximately 17 mm to 900+ mm and is interchangeable with equivalents from other manufacturers using standard ISO designations. SEPL stocks both inch and metric sizes ex-Ahmedabad for Gujarat customers.
What causes tapered roller bearing failure and how can it be prevented?
The four most common failure modes in tapered roller bearings are: incorrect preload setting (too tight or too loose), inadequate or contaminated lubrication, improper mounting (hammer blows on the wrong ring), and misalignment exceeding bearing tolerance. Timken’s engineering guidelines cover all four — SEPL can provide mounting and lubrication specifications along with any bearing supply to help plant teams avoid repeat failures.
Is SEPL an authorised Timken tapered roller bearing dealer in Ahmedabad?
Yes — Santram Engineers Pvt. Ltd. is an authorised Timken distributor in Gujarat covering Ahmedabad, Rajkot, Morbi, Mehsana, Surat, Ankleshwar, Bharuch, and Gandhidham. This is confirmed by Timken’s official Authorized Distributor certificate issued by Sanjay Koul, CMD Timken India Limited, valid from 26th June to 31st December 2026. Unlike general bearing traders on IndiaMART, SEPL supplies genuine Timken products with full manufacturer warranty documentation.
