HRE20035 295 mm 200 mm 35 mm Frequently Asked Questions about HRE20035 HRE Series Crossed Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each HRE20035 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 (200 mm bore side) ensures perfect planar contact without edge binding.
To match diverse operational dynamics, CHG Bearing supplies HRE20035 with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing HRE20035 correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
When fitting HRE20035 over a 200 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.
