All inch cam follower bearings have a black oxide finish on all external surfaces.
Key Features
Structural Design
Composed of machined thick-walled outer rings, needle rollers or cylindrical rollers, retainers (or fully loaded rolling elements), inner rings, and seals. Some models include bolted shafts for easy installation.
Sealing Performance
Most models feature sealing structures that effectively prevent dust, moisture, and pollutants from entering, extending service life and making them suitable for harsh working environments.
Outer Ring Design
Outer circle can be cylindrical or curved, which helps with automatic centering, reduces edge stress, and improves smooth operation.
Material & Lubrication
Constructed from high carbon chromium bearing steel (GCr15) for high strength, hardness, and wear resistance. Wide inner ring allows for slight axial displacement while maintaining sealing effect, with lubricating oil holes for supplementary lubrication.
Technical Specifications
Frequently Asked Questions
What's the difference between CYR and NATV series?
Both are cam followers in inch sizes. The CYR series features black oxide surface treatment, while NATV series comes in natural metal color.
Where are cam followers used?
Widely applied in machine tools, metallurgical machinery, textile machinery, printing machinery, and processing assembly lines.
Why choose cam follower track rollers over other bearing types?
Specifically engineered for track operations, transmission devices, and conveyor systems where direct rolling on raceways is required.
How to select cam follower sizes?
Determine by inner diameter, which specifies the compatible shaft diameter for installation.
Proper Installation Procedure
Step 1: Lubrication
Apply lubricating grease or oil to the lubrication groove, ensuring complete coverage of rolling surfaces.
Step 2: Inner Ring Tight Fit
Use a sleeve to press evenly onto the shaft, avoiding tilting during installation.
Step 3: Outer Ring Loose Fit
Press directly into seat hole, using a copper rod to distribute impact force when hammering.
Common imperial models widely used in forklifts, conveying equipment, and similar applications.
CCYR Series
Similar to CYR series with slight structural differences, commonly used as substitutes for imported components and supporting non-standard customization.
