36048 360 mm 240 mm 218 mm Frequently Asked Questions about 36048 Four-Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model 36048 is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 240 mm) and steep thermal gradients between inner and outer rings.
Each 36048 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (240 mm bore side) ensures perfect planar contact without edge binding.
When fitting 36048 over a 240 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
Beyond standard alloy steel, CHG Bearing can customize the 36048 Four-Row Tapered Roller Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
