Drive track bearing LFR-5 series

stainless steel

Running rollers with a raceway profile have balls as rolling elements and an optimized V groove incorporated into the outer ring. Hardened shafts serve as parallel partners. In addition to radial forces, they can also absorb axial forces. 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. NPP: integrated contact seals; alternative designation 2RS, HRS KDD: integrated dust shields with a gap for low-friction motion with a limited protective effect; alternative name ZZ or 2Z Track rollers are usually lubricated for life. Coated track rollers with profiled outer ring 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.
