LFR series guide roller bearing linear guide roller is the most widely used, economic and practical products, can be adapted to cylindrical guide, smooth operation, small error, running noise is very low, running speed is very high.
the contact between the roller and the guide rail is 60 degree contact, with good contact performance and running resistance is very small, so as to achieve a long service life.
the roller adopts double row angular contact ball bearing internal structure design and thickened outer ring, so that the roller has a higher bearing capacity, roller bearing configuration eccentric wheel and concentric shaft after simple installation.
the roller is made of high quality bearing steel or stainless steel, processed by heat treatment, precision grinding and filled with high quality multi-purpose grease with long life. Roller dust protection with metal dust cover (KDD) or rubber seal ring (NPP).
LFR520NPP Custom Ball Bearings Advantages:
1. High-quality steel: Ultra-clean steel bearings extend up to 80% of life.
2. Advanced grease technology: Seiko grease, can extend life and performance.
3. Super finished raceway: special grinding to reduce noise, improve lubricant distribution and life.
4. Patent seals provide protection against pollution in the worst environments.
5. Quality Assurance: 100% testing to ensure the quality of the whole product.
