NATV 20 PPA SKF Support Roller Bearing, Full Complement Needle Roller, Dual Lip Axial Seals, 20mm ID x 47mm OD x 25mm W
The SKF NATV 20 PPA is a premium, heavy-duty yoke-type support roller (track roller) designed to guide linear motion systems and handle high radial loads. Part of the NATV series, this bearing features a full complement of uncaged needle rollers within a thick-walled outer ring. This design provides maximum contact area to withstand intense pressures and shock loads.
The advanced PPA configuration incorporates a specialized profile on the outer ring running surface to optimize load distribution and prevent edge stresses. Additionally, it features high-efficiency axial sliding rings made of engineered plastic, combined with dual-lip labyrinth rubber seals on both sides. This sealing setup locks in the factory-charged premium grease and provides excellent defense against dust, moisture, and cutting fluid contamination.
