Overview
RBC4-0107
The four-row cylindrical roller bearing without an inner ring is composed of two outer rings. Each outer ring includes a roller and cage assembly. This bearing is usually used in hardening and grinding raceways. If there is no inner ring, a larger shaft diameter can be used to provide a stronger and harder shaft. The bearing can accommodate the displacement in both axial directions and is only limited by the width of the cable tray.
Since the invention of the first set of self-aligning ball bearings 100 years ago, SKF has gradually evolved into a knowledge-based company and has now provided customers with unique solutions in five major technical areas. These areas include bearings, bearing units and seals, and of course also expanded to other areas including: lubricants and lubrication systems, which play a vital role in the life of bearings in many application areas; mechatronics, which combines mechanics and electronics Knowledge integration is applied to the system, resulting in a more effective linear motion and induction system; and a complete set of services, from design and logistics support to condition monitoring and reliability systems.
SKF’s business is divided into three major departments: Industry Department, Automotive Department and Service Department. Each business unit provides services to the global market, focusing on customers and industries related to its own business.
SKF was established in 1907 and has attached great importance to product quality, technology research and market development from the very beginning. The group has invested tremendous efforts in technical research and product development, and has continuously made various inventions and creations, set new standards in the field of bearing technology, and introduced new products to the bearing market. Although the scope has expanded, SKF still maintains a world-leading position in the design, production and market development of rolling bearings, as well as in supplementary models and products such as seals. SKF has always maintained an increasingly important position in the market of linear motion products, high-precision aerospace bearings, machine tool spindles and equipment maintenance services.
