Needle Roller Bearing NAST25ZZ

The support roller needle bearing with a thick outer ring, which is quenched at high temperature and high nitrogen. The high-precision sorted roller is guided by the rib of the high-rigidity outer ring. With linear contact, the roller can easily rotate directly on the raceway and can withstand huge loads.

In order to remove stress, the outer ring of the support roller adopts a curved surface design. The curve roller has various specifications and models with single and double seals, without seals, and with seals. The seal ring has a large space for storing grease, provides long-term lubrication of lithium-based grease, and extends the lubrication interval. The seal ring is made of skeleton nitrile rubber or ST12, and its operating temperature range is -30°C to +100°C or -30°C to +180°C. The close-fitting curve roller can withstand heavy and extremely strong loads and high-performance operation.
