HRE25025 310 mm 250 mm 25 mm Frequently Asked Questions about HRE25025 HRE Series Crossed Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting HRE25025 over a 250 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.
Each HRE25025 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 (250 mm bore side) ensures perfect planar contact without edge binding.
To safeguard CHG Bearing HRE25025 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (250 mm x 310 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Built for demanding industrial environments, the HRE25025 HRE Series Crossed 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.
