Single-row tapered roller bearings are designed to accommodate combined loads, i.e. simultaneous radial and axial loads. The projection lines of the raceways meet at a common point on the bearing axle to ensure true rolling action and thus low friction moments during operation. The axial load capacity of tapered roller bearings increases with increasing contact angle. Features: low friction. The optimised roll-end design and surface finish on the flange promote the formation of lubricant films, resulting in less friction. This also reduces frictional heat and flange wear. In addition, the bearings can better hold the preload and run at reduced noise level.Improved operational safety.Optimised surface texture on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricating film.Rigid bearing applicationA single-row tapered roller bearing is typically adapted against a second tapered roller bearing single-row roller bearing. By applying a preload, a rigid bearing application can be achieved. Separable and replaceable. The inner ring with roller and cage mounting (cone) can be mounted separately from the outer ring (cup). Furthermore, the divisible components are interchangeable. This facilitates assembly, disassembly and maintenance inspection routines.SpecificationUnit system: metric.Bore diameter d: 35 mm.Outer diameter D: 80 mm.Total bearing width T: 32.75 mm.Inner ring shoulder diameter d1: 54.85 mm.Width inner ring B: 31 mm.Width outer ring C: 25 mm.Corner radius inner ring r1.2 minmin: 2 mmCorner radius inner ring r: 2 mm.
