The bearing is designed with double row angular contact ball bearing internal structure and thicker outer ring, so that the bearing has higher load-bearing capacity. 2. Bearings are made of grease bearing steel (AISI52100 or stainless steel AISI440C) and processed by heat treatment and precision grinding. They are high quality and versatile oils with long life in the interior. Bearing dust-proof cover is made of metal dust-proof cover. Bearings with   communication shafts and eccentric shafts can also be provided. 3. The V-groove bottom of the bearing outer ring has a knife retracting groove, and other V-angle bearings can also be customized.   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.     Shipping Method:   1. For small amount (GW<100KGS), we can send you by express, such as DHL, Fedex, TNT etc 2. For GW between 100KGS to 500KGS, we can send you by sea shipping or air shipping 3. For large amount (GW > 500KGS), we can send you by sea   Factory Photo:       Working principle:   1.Custom Ball Bearings can bear radial load, radial load and axial load. 2.When it only bears radial load, the contact Angle is zero. When the deep groove ball bearing has a large radial clearance.   3.It has the performance of angular contact bearing and can bear a large axial load.   How to Place an Order:   1.
