Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing 132.45.2240.03 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (2019 mm x 2461 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Each 132.45.2240.03 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 (2019 mm bore side) ensures perfect planar contact without edge binding.
In its sealed configuration (Open Type), CHG Bearing pre-charges 132.45.2240.03 with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
Engineered according to international ISO boundary plans, CHG Bearing supplies 132.45.2240.03 with a precision bore diameter (d) of 2019 mm, an outside diameter (D) of 2461 mm, and a nominal ring width (B) of 231 mm. This configuration yields an effective cross-sectional wall thickness of 221.0 mm and an envelope ratio (D/d) of 1.22, delivering compact rigidity for OEM machinery housings.
