Support roller bearings are bearing units composed of machined thick walled outer rings, needle or cylindrical rollers, or cage guided or fully loaded rolling element groups, inner rings or bolts, and seals. They can withstand high radial loads and certain impact loads, and have compact and diverse structures, high rotational accuracy, a wide variety of varieties, wide adaptability, and easy installation. Widely used in machine tools, metallurgical machinery, textile machinery, printing machinery and other mechanical equipment and processing assembly lines.

essential information

The STO, NA22, and 2RS series products can be used for high-speed operation during oil lubrication.

The NATR series support rollers are particularly suitable for heavy loads and medium speeds.

The NATV, NUTR, KRV, and NUKR series of fully loaded rolling element products can withstand heavy loads at low speeds.

This type of bearing adopts a needle roller or cylindrical roller bearing structure; There are various sealing forms used to prevent the invasion of pollutants and water; The outer circle has various contour shapes, including cylindrical and circular shapes; The useful bolt shaft structure is convenient for direct installation and other various structural forms for different occasions to choose from. Special structures and other requirements can be customized to meet the needs.

Supporting roller needle bearing

The thick walled outer ring is quenched with high temperature and nitrogen, and the high-precision sorted rollers are guided by the high rigidity outer ring's edge. By using linear contact, the rollers can easily rotate on the raceway and withstand huge loads. To remove stress, the outer ring of the supporting roller adopts a curved design, and the curved roller has various specifications and models with single or double sealing rings, without sealing rings, and with sealing rings. With a sealing ring, there is a large space for storing lubricating grease, providing long-lasting lubrication with lithium based grease, and extending lubrication intervals. The sealing ring material is nitrile rubber with a skeleton or ST12, and its operating temperature range is -30 ° C to+100 ° C or -30 ° C to+180 ° C. The tightly mounted curved roller can withstand heavy extremely strong loads and operate with high performance.
