High-Rigidity Roller Stud Mounted Cam Follower from China's Leading Suppliers and Factory
Types & Configurations
🔩 Stud-Type Cam Followers (CF Series)
One-piece stud design with threaded or unthreaded shanks. Standard for linear motion systems.
🔗 Yoke-Type Roller Followers (CRY Series)
Designed with yoke lugs for pivot mounting. Used in linkage mechanisms.
⚙️ Eccentric Stud Types (CF-E Series)
Eccentric stud allows radial adjustment (±0.5–2 mm) for precise alignment.
⭕ Crowned vs. Flat Outer Rings
Crowned rings compensate for misalignment; flat rings maximize contact area.

Frequently Asked Questions
Q
What is the difference between stud-type cam followers and yoke-type roller followers?
Stud-type cam followers (e.g., CF Series) feature a one-piece stud design with threaded or unthreaded shanks and are the standard choice for linear motion systems. Yoke-type roller followers (e.g., CRY Series) use yoke lugs for pivot mounting and are specifically suited for linkage mechanisms where rotational mounting is required.
Q
When should I choose an eccentric stud type cam follower?
Eccentric stud types (e.g., CF-E Series) are ideal when precise radial alignment is required. The eccentric stud allows for radial adjustment in the range of ±0.5–2 mm, making them the preferred option in applications where installation tolerances need fine-tuning after assembly.
Q
What are the speed limitations of cam followers, and why?
Cam followers are typically rated for speeds of ≤ 500 rpm. This limitation is due to the sliding contact risks that arise at higher speeds, which can cause increased heat generation, accelerated wear, and potential lubrication breakdown. For high-speed applications, additional cooling or specialized lubrication may be required.
Q
What materials are used in cam followers, and why are they important?
Outer rings are made from case-hardened chromium steel (SUJ2), which provides excellent surface hardness and wear resistance. Studs are manufactured from alloy steel (SCM420 or SCM440) for high tensile strength and durability. These material choices ensure compliance with ISO 9001 and JIS B1552 standards, guaranteeing consistent performance under demanding load conditions.
Q
What is the advantage of crowned outer rings over flat outer rings?
Crowned outer rings are designed to compensate for angular misalignment between the roller and the cam or track surface, reducing edge loading and extending service life in applications where perfect alignment is difficult to achieve. Flat outer rings, on the other hand, maximize the contact area with the mating surface, making them more suitable for applications requiring higher load distribution under well-aligned conditions.
Q
Are there maintenance-free cam follower options available?
Yes. Sealed and pre-lubricated cam follower variants are available for applications where regular maintenance access is limited or inconvenient. These units are factory-filled with grease and sealed to prevent contamination, offering long service intervals and reduced total cost of ownership, particularly in automated assembly lines and robotics applications.
