BK 2 low lubricating sliding bearing

BK 2 is similar to BK 1 but with a POM Acetal sliding surface with grease pockets instead of PTFE. This sliding bearing are more suited for edge loads due to the greater tolerance in misalignment and in dirty environments where relubrication is possible. BK 2 does not need more than inital lubrication, but regular lubrication will considerably extend the life span.
