How much do you know about follower bearing?

Follower bearing is a bearing unit composed of machined thick-walled outer ring, needle roller or cylindrical roller, cage guide or full complement rolling element group, inner ring or bolt and seal, follower bearing can withstand higher radial load And a certain impact load, compact and diverse structure, high rotation accuracy, wide variety, wide adaptability, and easy installation. Widely used in machine tools, metallurgical machinery, textile machinery, printing machinery and other mechanical equipment and processing lines.

Among them, follower bearings of STO, NA22...2RS series can be used for high-speed operation during oil lubrication.
The follower bearings of the NATR series are particularly suitable for heavy loads and medium speeds.
NATV, NUTR, KRV, NUKR series full complement rolling element follower bearings can bear heavier loads at low speeds.
The follower bearing adopts needle roller or cylindrical roller bearing structure; there are various sealing forms to prevent the intrusion of contaminants and water; the outer circle of the outer ring has various contour shapes of cylindrical and arc shapes; useful bolt shaft structure It is convenient for direct installation and other structural forms for different occasions to choose and use, and those with special structure and other requirements can be customized to meet the needs.

The follower bearing is a thick-walled outer ring, which is quenched at high temperature and high nitrogen. The rollers of high-precision sorting are guided by the ribs of the high-rigidity outer ring. Using linear contact, the rollers can easily rotate directly on the raceway, and can withstand huge load. In order to remove the stress, the outer ring of the follower bearing is designed with a curved surface, and the curved roller has various specifications such as single, double sealing ring, without sealing ring, with sealing ring and so on. With sealing ring, the grease storage space is large, it provides long-term lubrication of lithium-based grease, and prolongs the lubrication interval. The seals are made of skeletonized nitrile rubber or ST12 and have an operating temperature range of -30°C to +100°C or -30°C to +180°C. Close-mounted curved rollers can withstand heavier extreme loads and high-performance operation.
