Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Sourcing N 1012 KTNHA/HC5SP 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 Super-Precision Cylindrical Roller Bearings.
Each N 1012 KTNHA/HC5SP 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 (60 mm bore side) ensures perfect planar contact without edge binding.
Built for demanding industrial environments, the N 1012 KTNHA/HC5SP Super-Precision Cylindrical Roller Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
The CHG Bearing N 1012 KTNHA/HC5SP is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
