BRM80 Bushes
The BRM80 bushes has the through-holes on bushes,which has a greater capacity to collect the lubricant compared with the indentations. These indents serve as lubricant reservoirs to rapidly build up a lubrication film in the start movement and therewith reduce the start friction. The material suitable for constructions, agriculture etc where high load and slow movement are occurring.
Ths bushes should be reduced by 15% in consideration of the through-holes.
Easy of fitting and lubrication
