PR4.455 (Size:35x73.8x44-45.5mm) Eccentric Adjustable Composite Roller Bearing
The PR4.455 bearing is a Combined Bearing with an inner diameter of 35 mm , an outer diameter of 73.8 mm, a width of 44-45.5 mm. It primarily bears Axial and Radial, Its dynamic radial rated load is approximately 45.5 (kN), its static radial rated load is approximately 51 (kN). Its dynamic axial rated load is approximately 13 (kN), its static axial rated load is approximately 14 (kN). together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
Application: Loaders and Unloading Machines, Palletizers, Cranes and Hoists, Horizontal and Vertical Feed and Lift Units, Forklift Trucks, ASRS Systems, Shrink-Wrappers

PR4.455 Adjustable Combined Roller Bearings with less clearance between beearing and profile, bearings are lubricated for life.
Adjusting of the axial bearing:
1. loosen screws
2. turn eccentric axle (axial bearing will be turned)
3. check measure A (if neccessary repeat Pos.2)
4. secure screws with loctite
5. lock screws
Applications: Originally used in fork trucks. Combined roller bearings can be used in a variety of applications such as Loaders and Unloading Machines, Palletizers, Cranes and Hoists, Horizontal and Vertical Feed and Lift Units, Forklift Trucks, ASRS Systems, Shrink-Wrappers, among others.
