Stud Cam Follower KR 47 PP, 20mm ID, 47mm 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 cam follower is an essential component in various mechanical systems, designed to support radial loads efficiently. The unit features a roller diameter of 47mm and a bore size of 20mm, making it suitable for a range of applications. Its robust steel construction ensures durability and reliability in demanding environments.

• Static load rating of 25kN provides high-load capacity

• Designed for easy mounting with a recommended torque of 120 N·m
• Limiting speed of 3000 r/min supports high-speed operations
• Lightweight at 0.381kg facilitates ease of installation

• Used for automation for guiding and supporting mechanical arms
• Ideal for electrical assemblies for precise movement control
• Suitable for mechanical systems requiring reliable radial load support
• Recommended for manufacturing machinery and conveyor systems

The static load rating of 25kN indicates the maximum load that the cam follower can withstand when at rest, ensuring it maintains structural integrity under heavy loads without risk of failure, thus providing reliable support in various applications.

A dynamic load rating of 14.7kN enables the cam follower to perform effectively under varying operational conditions, minimising wear and enhancing its service life, which translates to lower maintenance costs and reduced downtime for machinery.

A concentric bearing system maintains optimal alignment during operation, reducing eccentric loads and ensuring smoother movement. This design contributes to the overall reliability and efficiency of the mechanical systems it supports.
