High-Rigidity Roller Stud Mounted Cam Follower - China Suppliers & Factory with Load Capacity and Sealing Solutions
Types & Configurations
🔩 1. Stud-Type Cam Followers (CF Series)
One-piece stud design with threaded or unthreaded shanks. Standard for linear motion systems.
🔗 2. Yoke-Type Roller Followers (CRY Series)
Designed with yoke lugs for pivot mounting. Used in linkage mechanisms.
⚙️ 3. Eccentric Stud Types (CF-E Series)
Eccentric stud allows radial adjustment (±0.5–2 mm) for precise alignment.
🔄 4. 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 with a threaded or unthreaded shank, making them ideal for linear motion systems. Yoke-type roller followers (e.g., CRY Series) use yoke lugs for pivot mounting and are better suited for linkage mechanisms where rotational mounting is required.
Q When should I choose a crowned outer ring over a flat outer ring?
Choose a crowned outer ring when your application involves shaft or track misalignment, as the crowned profile distributes load more evenly under angular deviation. Flat outer rings are preferred when precise alignment is guaranteed and maximum contact area is needed for higher load capacity.
Q What materials are cam followers typically made from?
Outer rings are typically made from case-hardened chromium steel (SUJ2) for high surface hardness and wear resistance. Studs are manufactured from alloy steel grades such as SCM420 or SCM440. These materials comply with ISO 9001 and JIS B1552 standards.
Q What is the maximum operating speed for cam followers?
Cam followers are generally rated for speeds up to 500 rpm. Exceeding this limit increases the risk of heat buildup and premature wear due to sliding contact between the rolling elements and raceways. For higher-speed applications, consult the manufacturer's specifications for the specific series.
Q Are there maintenance-free cam follower options available?
Yes. Sealed and pre-lubricated variants are available for applications where regular re-lubrication is impractical. These are particularly useful in food processing, cleanroom environments, or any system where minimizing maintenance downtime is a priority.
Q How do eccentric stud cam followers improve alignment?
Eccentric stud cam followers (e.g., CF-E Series) feature an offset stud that can be rotated to shift the roller's center position radially by ±0.5 to 2 mm. This built-in adjustability allows fine-tuning of track contact without repositioning the entire mounting assembly, saving time during installation and maintenance.
