Category Information
Bearings - Tapered Roller ConeTapered Roller Cone Bearings. Replacements for existing tapered roller cones (inner part). Match with part number on your existing bearing. It is recommended that you change both cup and cone whenever possible.
- Tapered roller bearings provide for high thrust and axial loads, and are commonly used in automotive applications such as wheels, differentials and gearboxes.
- Match the cone with the appropriate cup as listed in the tables. Sometimes there will be a range of cups to suit. Be sure to check the dimesions thoroughly.
- The cup is the outer part of the bearing, and has no rollers. An expanded range may be available on special order. Please enquire.
