Bushing inner-Ø after mountingH9
Shaft tolerancef7 to h8
Steel, hardened or untempered, surface roughness ≤ Rz 6.3
Housing: Mounting bevel min. 1.5 mm x 15-45° Shaft: Mounting bevel 5 mm x 15°, edges roundedThe application of an adequate force fitting mandrel is advisable. Grease lubrication of the outer surface may be necessary when mounting.
BRO-MET® is a low-maintenance bronze sliding bearing. Primary lubrication is necessary. Oil or grease lubrication is possible. Due to lubrication pockets, clearances are reduced to a minimum.
Range of Application
Hydraulic cylinders, construction machines, crane construction, agricultural machines (impact loading)
