Bearing KR 16 PPX INA – High-Quality Linear Bearing for Precise Motion
The bearing KR 16 PPX INA is a premium linear bearing designed to provide smooth, reliable, and low-friction motion in a wide range of industrial and mechanical applications. Manufactured by INA, part of the renowned Schaeffler Group, this bearing is engineered to deliver exceptional performance and durability, making it an ideal choice for automation systems, CNC machinery, and other precision equipment.
Key Features of the Bearing KR 16 PPX INA
- Type: Linear ball bearing
- Designation: KR 16 PPX INA
- Design: Open, self-lubricated bearing with polymer cage
- Construction: High-quality steel outer ring with integrated polymer cage for reduced friction and noise
- Sealing: Open design without seals, suitable for clean environments or applications with external protection
Technical Characteristics and Application
The KR 16 PPX INA is specifically tailored for use with precision ground shafts, providing excellent linear guidance and minimal radial clearance. While the exact dimensions such as bore diameter (16 mm) can be inferred from the product designation “16” indicating a 16 mm shaft diameter, detailed width and outer diameter specifications should be confirmed from the official INA datasheet for exact fitment.
This bearing type is particularly favored in automated machinery where smooth linear motion is critical, including robotics, packaging machines, and medical devices. The polymer cage significantly reduces maintenance requirements by minimizing lubrication needs and extending service life.
Benefits of Using KR 16 PPX INA Bearings
- Enhanced precision and smooth linear movement
- Reduced maintenance due to self-lubricating polymer components
- Corrosion resistance and noise reduction in operation
- Compatibility with standard 16 mm shafts for easy integration
- Reliable performance under moderate load and speed conditions
