Roller bearings
Tapered Roller Bearings
A cone, a cup and a ring of tapered rollers. The geometry takes combined radial and axial load in proportion to the contact angle, which is why it still anchors the wheel hub.

Design
The angle sets the split.
Every batch is measured on the finished part, and the measurement file travels with the goods. Send a designation, a drawing or a photo of the failed part and an engineer will answer with a lead time and a price, usually inside 48 hours.
- Metric and inch seriesISO series for new designs, inch series for US and UK legacy equipment.
- Contact angle sets the splitSteep angles carry more thrust, shallow angles run cooler at speed.
- Matched pairsCups and cones supplied as a matched pair where axial setting has to be predictable.
- Case-hardenedRollers and rings case-hardened for shock load in hub and final-drive service.

Where it is used
Common applicationsWheel hubs
Car, trailer and commercial-vehicle hubs with combined load.
Final drives
Axle and differential pinion supports.
Gearboxes
Helical and bevel shafts where axial load follows the helix angle.
Machine spindles
Low-speed spindle noses where stiffness matters more than speed.

A designation, a drawing, or a photo of the failed part is enough to start. Technical questions reach an engineer, not a mailbox.
