DuraLubeDuraLube self-lubricating spherical plain bearings provide grease-free operation, thanks to a durable liner system that reduces friction between the spherical surfaces of the inner and outer rings. The bearings do not require initial lubrication, nor do they require lubrication during operation. They minimize maintenance costs and make maintenance easier because they don't attract and hold dirt like grease-fed bearings.
