HRE35020 400 mm 350 mm 20 mm Frequently Asked Questions about HRE35020 HRE Series Crossed Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing HRE35020 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.
To safeguard CHG Bearing HRE35020 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (350 mm x 400 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Absolutely. The CHG Bearing HRE35020 HRE Series Crossed Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF HRE35020, FAG HRE35020, NSK HRE35020. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Model HRE35020 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 350 mm) and steep thermal gradients between inner and outer rings.
