Supporting roller bearings are bearing units composed of machined thick walled outer rings, needle rollers or cylindrical rollers, or cage guides or fully loaded rolling element groups, inner rings or bolts, and seals. They can withstand high radial loads and certain impact loads, have compact and diverse structures, high rotational accuracy, a wide variety of varieties, wide adaptability, and are easy to install. Widely used in mechanical equipment and processing lines such as machine tools, metallurgical machinery, textile machinery, printing machinery, etc.
The STO, RSTO, NA22... 2RS, RNA22... 2RS series products can be used for high-speed operation when lubricated with oil. The NATR and NAST series support rollers are particularly suitable for heavy and medium loads. 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 arc shapes; There are various structural forms available for different occasions, such as the use of bolt shaft structure for easy direct installation, and customization can be made to meet special structural requirements.
