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 500KDH7201+K, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
Absolutely. The CHG Bearing 500KDH7201+K Double Row Tapered Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 500KDH7201+K, FAG 500KDH7201+K, NSK 500KDH7201+K. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
When fitting 500KDH7201+K over a 500 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.
The CHG Bearing 500KDH7201+K 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.
