Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Sourcing 81244 directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Cylindrical Roller Thrust Bearings.
To match diverse operational dynamics, CHG Bearing supplies 81244 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.
To safeguard CHG Bearing 81244 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (220 mm x 300 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
As standard production, CHG Bearing subjects 81244 to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
