Stud Cam Follower KR 30 PPA, 12mm ID, 30mm OD

Cam followers of the KR design are fitted with needle rollers and have a thick outer ring making them suitable for shock loads.

Concentric cam follower
The outer ring is guided via the integral flange at the head of the stud and the pressed on side washer
SKF Cam followers on the PPA design have axial slide rings of polyamide 66
These slide rings reduce the friction and give relatively cool operation that is advantageous for the grease service life
In the radial direction the slide ring forms a narrow gap to the outer ring that protects against course contaminations
Operating temperature range is -30 to +100°C
The PPA design has an improved profile of the runner surface which gives a better stress distribution, also under misaligned conditions
The PPA design has a crowned running surface
Supplied with grease nipples
Lubrication can be done at the Head or thread end, except KR 16 & 19 which can only be lubricated at the head

This stud cam follower from SKF is designed for cam (computer-aided manufacturing) systems in heavy industrial environments. The cylindrical design and threaded pin make for quick and easy installation, while the thick outer ring is sturdy enough to resist shock loads. The cam follower comes ready to mount. Just put it in place and secure it using an Allen key. Lubrication can be done at either the head or the thread end, making maintenance as easy as possible.

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.
