Product Overview:
The KB 0522 PP RICH is a high-precision linear ball bearing designed for smooth, low-friction translational movement along a 5 mm hardened shaft. Built to the European (EU) standard, this bearing features a compact 12 mm outer diameter, making it ideal for precision laboratory equipment, 3D printers, and small-scale automation. The internal structure consists of a lightweight plastic cage that guides multiple rows of recirculating steel balls, ensuring consistent linear guidance and high travel speeds. The "PP" designation indicates that the bearing is equipped with integrated single-lip seals on both ends, which effectively retain the internal lubricant while preventing the ingress of dust and fine particles. Its minimalist, non-flanged design allows for easy integration into standard bearing housings or custom-machined blocks.
Key Performance Advantages:
- Low Friction Coefficient: Recirculating ball technology ensures smooth movement with minimal resistance.
- European Standard Compliance: Dimensions and tolerances adhere to EU norms for universal compatibility.
- Dual Integrated Seals (PP): Protects internal components from contamination, extending the maintenance intervals.
- Lightweight & Quiet: The plastic cage design reduces overall mass and minimizes operational noise during high-speed travel.
Transparency Note: This bearing is manufactured under the RICH brand. The code KB 0522 PP is used solely for identification and do not imply affiliation with other manufacturers.
