Product Details

Wrapped Bronze Sliding Bearing with Lubrication Holes WB802 Bronze Bushing CuSn8P0.3 CuSn6P


 

ZR-092 bronze rolled bearing bushing is made from high grade alloyed, hot rolled, phosphorous tin bronze. The entire bearing surface consists of “punched-through-holes” that provides improved lubricating properties and fewer maintenance periods that reduces friction, both at startup and during operation.

 

ZR-092 bronze bushing is a low-maintenance bronze plain bearing. However, initial lubrication is required—both oil and grease lubrication are possible. This type of bronze bearing is intended for radial, oscillating and axial movements and are especially for high load capacity and strength with low wear, suitable for rough operation, corrosion resistant

 

This type of bronze bearing also called FB092 bronze sliding bearing, WB802 bronze bearing,PRM bronze wrapped plain bearings,MBZ-B09 LD Plain bronze bearing,BMZ/L Bronze self lubricating bearing, BRM-80 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
