WF-WB800 Rolled Flanged Bronze Bearing Bushing with Oil Pockets
ZR-090F Flanged bronze bushing is manufactured of a cold formable homogenous bronze, which because of this will obtain exceptional material properties. The execution of the flange permits that the bearing also can carry axial loads. The standard sizes are fitted with diamond-shaped lubrication indents on the bearingsurface.
These indents serve as lubricant reservoirs i.a. to rapidly build up a lubrication film in the moment of start and therewith reduce the start friction. The properties of the WB700-material, together with the procedure of wrapping and calibration, make this type of bearing especially suitable for constructions, where medium or high loads and relatively slow movements are occurring
This type of bronze bearing also called FB090 Flanged bronze sliding bearing, WB WF 800 bronze bearing,PRM bronze wrapped plain bearings,MBZ-B09 Plain bronze bearing with collar,BMZ Bronze flanged self lubricating bearing, BRM-10 flanged bronze sliding bearings and etc.

Mounting Suggestion
Housing ØH7
Bushing inner-Ø after mountingH9
Shaft tolerance f7
Housing: Mounting bevel min. 1.5 mm x 15-45°
Shaft Material: Steel, hardened or untempered, surface roughness ≤ Rz 4-6
Shaft: Mounting bevel 5 mm x 15°, edges rounded
The application of an adequate force fitting mandrel is advisable. Grease lubrication of the outer surface may
be necessary when mounting.
Stick-in: Adhesive should not contact the sliding surface
