1.Low friction The optimized roller end design and surface finish on the flange promote lubricant film formation, resulting in lower friction. This also reduces frictional heat and flange wear. 2.Enhanced operational reliability Optimized surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film. 3.Consistency of roller profiles and sizes The dimensional and geometrical tolerances for the tapered roller bearings is practically identical. This provides optimal load distribution, reduces noise and vibration, and enables preload to be set more accurately. 4.Rigid bearing application A single row tapered roller bearing is typically adjusted against a second tapered roller bearing. By applying a preload, a rigid bearing application can be achieved. 5.Separable The inner ring with roller and cage assembly (cone) can be mounted separately from the outer ring (cup).Main Dimensions: Bore diameter(d):15mm Outer diameter(D): 35mm Width of inner ring(B): 11mm Width of outer ring(C): 10mm Total width(T): 11.75 Chamfer dimension of inner ring(r )min.:0.6mm Chamfer dimension of outer ring( r) min.:0.6mm Dynamic load ratings(Cr):14.22KN Static load ratings(Cor): 13.05KN ABUTMENT DIMENSIONS Diameter of shaft abutment(da)max.:20 mm Diameter of shaft abutment(db) min.:20.5 mm Diameter of housing abutment(Da)min.:30 mm Diameter of housing abutment(Da)max.:30.5 mm Diameter of housing abutment(Db)min.:32 mm Minimum width of space required in housing on large side face(Ca)min.:2 mm Minimum width of space required in housing on small side face(Cb)min.:2.5 mm Radius of shaft fillet(ra)max.:0.6 mm Radius of housing fillet(rb) max.:0.6 mm30202 detail Specifications: Material:52100 Chrome Steel Construction:Single row Metric series Limiting speeds Oil: 15000rpm Limiting speeds Grease: 11000rpm Weight:0.055 kg
