Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Every production batch of CHG Bearing NU2348 Single Row Cylindrical Roller Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for NU2348. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
Beyond standard alloy steel, CHG Bearing can customize the NU2348 Single Row Cylindrical Roller Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
Each NU2348 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 (240 mm bore side) ensures perfect planar contact without edge binding.
