352236X2 320 mm 180 mm Frequently Asked Questions about 352236X2 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 352236X2 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 (180 mm bore side) ensures perfect planar contact without edge binding.
Standard batches of CHG Bearing 352236X2 conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
Engineered according to international ISO boundary plans, CHG Bearing supplies 352236X2 with a precision bore diameter (d) of 180 mm, an outside diameter (D) of 320 mm, and a nominal ring width (B) of 190 mm. This configuration yields an effective cross-sectional wall thickness of 70.0 mm and an envelope ratio (D/d) of 1.78, delivering compact rigidity for OEM machinery housings.
Model 352236X2 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 180 mm) and steep thermal gradients between inner and outer rings.
