Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing 6397/2319 Three-row Cylindrical Roller Slewing Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 2319 mm bore. For the mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for 6397/2319, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
To match diverse operational dynamics, CHG Bearing supplies 6397/2319 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.
Each 6397/2319 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 (2319 mm bore side) ensures perfect planar contact without edge binding.
