Model CF4-KR12
Outer Diameter 12mm
Inner Diameter M4*0.7
Load 180
Weight (G/PCS) 80
Unit Price/USD 0.4

The radial clearance of this bearing is smaller than general needle bearings to effectively increase the load domain. This helps absorb shock loads and ensures a longer, stable lifespan. Additionally, the rod ends have threaded or graded machining to simplify installation.


Design Features and Customization

The Bolt Type Wheel Roller Needle CAM Bearing CF4-KR12 follows the standard CF and CR series. The standard CF design means that rod-end diameters range from 3mm to 30mm, providing varied dimensions for wide applications.

For particular needs, ZLV also offers customization options to cater to different industries.


  1. High Rigidity & Precision: Suitable for CAM mechanisms and linear motion applications, providing high stiffness and accuracy.
  2. Corrosion Resistance: Stainless steel construction offers excellent corrosion resistance, suitable for environments where grease cannot be used, or where there might be water splashes or dust-free rooms.
  3. Cost-Effective: With a unit price of just USD 0.4 per meter, the CF4-KR12 offers a balance of performance and cost-efficiency.


  • Machine Tools: To achieve high precision and performance.
  • Industrial Robots: For efficient movement and weight-bearing.
  • Electronic Component Devices: Ensuring optimal functionality.
  • Office Automation Equipment: Enhancing overall productivity.

Final Remarks

ZLV’s Bolt Type Wheel Roller Needle CAM Bearing CF4-KR12 12mm is more than a bearing; it’s a component engineered to drive efficiency, stability, and innovation across various industries.
