Stud Cam Follower KR 80 PPA, 30mm ID, 80mm 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

From metalworking presses to conveying systems, this stud-type track follower from SKF is a go-to choice in cam systems. It converts rotary into linear motion. The design features thick outer rings to handle shock loads and accommodate axial slippage. There's a hexagonal recess at either end of the stud, so it can be easily mounted using an Allen key. Each of these recesses has a relubrication hole in the centre to help reduce friction, noise and wear and tear.

• For concentric ring slide and track system bearings
• Operating temperature range of -30 °C to +100 °C
• Bore size of 30 mm
• Roller diameter of 80 mm
• Static load rating of 85 kN
• Dynamic load rating of 42.9 kN

• Cam mechanisms
• Guideways
• Conveying and linear guidance systems
• Industrial and agricultural equipment

A cam follower with a crowned outer ring is beneficial for applications where edge stresses need to be minimized.

SKF stud cam followers come ready-greased. To ensure smooth operation, they should be relubricated regularly – especially in damp or contaminated environments – with the supplied grease nipples. Lubrication holes at the head and thread ends ensure a longer service life.
