This yoke type track roller guides and supports radial loads through a single row of full complement needle rollers running between a particularly thick-walled outer ring and an inner ring. Bore diameter is 25.0 mm, outside diameter 52.0 mm, and net mass 0.281 kg. Axial guidance of the outer ring is provided by plastic axial plain washers together with contact washers, forming a three-stage sealing arrangement (PP) on both sides of the needle roller bearing. The thick-walled outer ring gives the track roller high rigidity for direct rolling contact, while the full complement needle roller set increases radial load capacity within the given envelope dimensions. The plastic axial plain washers on both sides keep the outer ring axially located and restrict ingress of contaminants, so the bearing can run without an additional external guiding element. As supplied with PP sealing, it is intended for direct mounting on a shaft acting as an inner ring guide, requiring grease lubrication consistent with the sealing arrangement described.
