Double Row Angular Contact Roller Bearings

LR Series Roller Bearing Overview
LR series roller bearings enjoy a high reputation in the industry for their unique design and excellent performance. The outer circle of this series of roller bearings is processed into a cylindrical or crown shape (such as R500 arc surface). This design not only enhances the contact uniformity between the roller and the guide rail, but also significantly reduces stress concentration and friction resistance, thereby improving the service life and working efficiency of the product. LR series roller bearings are widely used in machine tools, glass fiber cable equipment, spring manufacturing machines, wire manufacturing machines and other occasions with high precision requirements.

Features of LR series roller bearings
High load capacity: LR series roller bearings adopt the internal structure design of deep groove ball bearings or double row angular contact ball bearings, and are equipped with thickened outer rings, which give them higher load capacity. At the same time, the roller is made of high-quality bearing steel, heat treated and precision ground, ensuring the strength and precision of the product.
Low friction resistance: The outer circle design of the roller with R500 arc surface makes the contact between the roller and the guide rail more uniform, avoids stress concentration, thereby reducing friction resistance and improving the operating efficiency and life of the product.
Convenient installation and maintenance: LR series roller bearings are available in two configurations: eccentric shaft and concentric shaft, making installation more convenient. At the same time, some double-row support rollers also have grease injection holes on the inner ring, allowing users to repeat lubrication through the grease injection holes to adapt to harsh working environments.
Sealed and dustproof: In order to ensure the normal operation of roller bearings in harsh environments, LR series roller bearings are sealed with metal dust covers or rubber sealing rings to effectively prevent the intrusion of dust and pollutants.
