Preset Hubs: The smart solution
These complete units combine hub and bearing. The requirements of the original equipment manufacturers (OEMs) are incorporated into the selection of the respective designs, as are uncompromising product tests and the extensive testing of the respective hub-bearing combination in the field. Manufacturing with a high degree of precision and the use of high-quality raw materials ensure the optimum function and usability of the preset hubs.
Preset Hubs: Advantages
- Preventing assembly errors
- Optimum tightness
- Less effort for installation (only one component)
- Reduced number of needed tools
- Manufacture of the hub-bearing combination to the highest quality standards
Compact Wheel Bearing Kits (Kit Wheel Truck (KWT)): Patented high-precision bearing sets
The wheel bearing kits consist of two preset high-precision bearings that are lubricated for life. They are used in all types of commercial vehicles and, among other things, offer optimum performance even under extreme loads due to their precisely adjusted axial play. The patented mounting solution ensures effective assembly.
Wheel Bearing Units (Hub Wheel Truck (HWT)): Compact and maintenance-free
These bearings for truck wheel hubs are preset bearing units with two inner sets and a common outer ring. They are lubricated for life and offer optimum performance even under high loads due to their compact design and the use of high quality grease. They are optimised for quick and easy mounting and dismounting on heavy vehicle wheel hubs.
Wheel Bearing Units (Compact Wheel Truck (CWT)): Integrated into the wheel hub
These compactly designed wheel bearing units are integrated into the wheel hub. They consist of two optimally aligned, lifetime-lubricated and preset bearings and offer simple and practical mounting or dismounting.
Tapered roller bearing (TRB): To all sides
This bearing type consists of an inner and outer ring and tapered rolling elements. Thanks to their geometry, tapered roller bearings can support combined loads, i.e. loads in both the axial and radial directions. In addition, these bearing designs also allow tilting moments to be accommodated.
