Frequently Asked Questions (FAQ)
What is the difference between Stud-Type and Yoke-Type Cam Followers?
Stud-Type cam followers (like the CF Series) feature an integrated, one-piece threaded or unthreaded stud for easy mounting in linear systems. Yoke-Type roller followers (like the CRY Series) use yoke lugs for mounting on shafts, making them highly suitable for linkage and pivot mechanisms.
When should I use a crowned outer ring instead of a flat outer ring?
Crowned outer rings are designed to compensate for angular misalignment and uneven loading during operation. Flat outer rings should be used when maximizing the contact surface area is critical to support heavier loads under precise alignment.
What is the adjustment range of Eccentric Stud Type Cam Followers?
Eccentric Stud Types (such as the CF-E Series) allow for a radial adjustment range of ±0.5 to 2 mm. This feature helps in fine-tuning and achieving precise alignment with the track surface.
Why do cam followers have a speed limit (typically ≤ 500 rpm)?
The speed limit of ≤ 500 rpm is primarily due to the sliding contact risks between the outer ring and the guide track, which can cause excessive heat and wear if operated at higher speeds.
What materials are typically used for high-performance cam followers?
High-performance cam followers use case-hardened chromium steel (SUJ2) for the outer rings to ensure wear resistance, and alloy steel (SCM420/SCM440) for the studs to handle high loads, complying with ISO 9001 and JIS B1552 standards.
Are there maintenance-free options available for cam followers?
Yes, sealed and pre-lubricated variants are available, which protect the internal bearings from contaminants and eliminate the need for regular re-lubrication, making them virtually maintenance-free.
