Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each NU3856 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 (280 mm bore side) ensures perfect planar contact without edge binding.
To safeguard CHG Bearing NU3856 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (280 mm x 350 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for NU3856. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
