BT4-8031E/C800/P5 815 mm 625 mm 480 mm Frequently Asked Questions about BT4-8031E/C800/P5 Four-Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each BT4-8031E/C800/P5 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 (625 mm bore side) ensures perfect planar contact without edge binding.
The CHG Bearing BT4-8031E/C800/P5 is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
Every production batch of CHG Bearing BT4-8031E/C800/P5 Four-Row Tapered Roller Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
Built for demanding industrial environments, the BT4-8031E/C800/P5 Four-Row Tapered Roller Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
