What are the advantages of the static load rating for this component?

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.

How does the dynamic load rating benefit operational efficiency?

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.

What is the impact of a concentric bearing system on performance?

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.

SKF Stud Type Track Rollers

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
