Guide track bearing STO

stainless steel

Like cam followers, yoke type track rollers have a reinforced outer ring that serves as a running area and preferably has a spherical design so that no edge stresses arise under high loads. However, cam followers do not have a threaded end but are instead installed on a suitable axle. In addition to radial forces, they can also absorb axial forces. Yoke type track rollers are available open or sealed - with or without axial guidance of the outer ring. Inadequate sealing can allow external environmental conditions to have an extremely negatively impact on running characteristics and thus a bearing’s service life. For this reason, bearings must be protected by seals. At the same time, seals also prevent lubricants from leaking. PP/2RS/2ZL: integrated contact seals. Only yoke type track rollers with seals are lubricated for life ex works, but can also be relubricated via a lubrication hole on the inner ring depending on their size. Designs with a V in their name are full complement designs. Full-complement designs have a significantly higher load rating, but this reduces the maximum speed. Coated needle-roller bearings The manufacturer Schaeffler offers its products with its special "Corrotect" coating. We also supply designs with a zinc-iron (ZnFe) and a zinc-nickel coating. Please indicate the desired resistance time in the salt spray test in hours, on the basis of which we will be able to select the necessary coating type. Stainless steel Various series are also available in stainless steel (AISI 440C, AISI420). Please ask us about this.
