2 | Wheel bearing | Standard Tapered Roller Bearing (TRB) Standard Tapered Roller Bearing (TRB) Product description: Tapered roller bearings bear high loads in a small installation space and exhibit good behaviour when cornering. They have been in use for over 100 years as the classical wheel bearing for commercial vehicles. They consist of an outer ring, and inner ring with rolling element and a cage. The outer ring and inner ring are removed and installed separately. Single-row tapered roller bearings are neither lubricated nor sealed. The bearing must be lubricated with suitable grease before installation. Regular removal of the hub due to maintenance, e.g. on the brake system, has a negative impact on the life of the tapered roller bearing: Penetration of dirt Improper re-lubrication Destruction of the seals Complicated re-adjustment of the bearing pair Note: For safety reasons and to prevent potential consequential damage, the inner and outer tapered roller bearings must always be replaced when replacing the wheel bearing! Furthermore, the wheel must be turned opposite to the direction of tightening during the adjustment process or tensioning. Assembly: 1. Clean wheel hub and check for oval deformation 2. Lubricate bearing inner ring, rolling element and cage with suitable grease 3. Press the outer bearing shell into the wheel hub 4. Position the greased inner rings with rollers and cage into the wheel hub 5. Insert the shaft seals to seal the wheel hub using a suitable tool 6. Position the wheel hub on the axle shaft 7. Secure the axle nuts and adjust the bearings according to the manufacturer's instructions EUROPART – Europe's No. 1 for truck, trailer, van and bus spare parts.
