Why should I lubricate cam followers?
Although SKF cam followers come ready-greased, you should re-lubricate them regularly with the supplied grease nipples. Lubrication reduces friction while the cam follower is in operation. This lengthens the working life of the product, minimising downtime for maintenance and lowering operating costs.
