31976X2P5 520 mm 380 mm N/A mm Frequently Asked Questions about 31976X2P5 Single Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for 31976X2P5, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
Model 31976X2P5 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 380 mm) and steep thermal gradients between inner and outer rings.
Sourcing 31976X2P5 directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Single Row Tapered Roller Bearings.
Each 31976X2P5 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 (380 mm bore side) ensures perfect planar contact without edge binding.
