Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing 132.50.4000.04 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (3718 mm x 4282 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
When fitting 132.50.4000.04 over a 3718 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.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 132.50.4000.04. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
To match diverse operational dynamics, CHG Bearing supplies 132.50.4000.04 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.
