The NATV 5 PPA Support rollers (yoke-type track rollers) mainly consist of a thick-walled outer ring, a yoke-type inner ring with mounting holes, needle rollers or cylindrical rollers, and a sealing device. The outer surface of the outer ring can be designed as a cylindrical or spherical surface, and the inner ring adopts an integrated yoke structure, directly fixed to the equipment with bolts.
Support rollers (yoke-type track rollers) have high load-bearing capacity. The thick-walled outer ring and needle roller structure provide excellent radial load-bearing capacity and strong impact resistance. Installation is simple, requiring no bearing housing; direct bolt fixing is sufficient. Operation is smooth, and some models with a spherical outer ring can automatically adjust to track deviations. They have good sealing performance and are suitable for harsh working conditions such as dust and humidity.
