61946X3M 329.5 mm 230 mm 40 mm Frequently Asked Questions about 61946X3M Deep Groove Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting 61946X3M over a 230 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
To extend the trouble-free lifespan of CHG Bearing 61946X3M, preventive maintenance routines should monitor operating housing temperature (normally maintaining below 70°C) and conduct regular vibration FFT analysis to identify early raceway micro-pitting before unexpected line halts occur.
Each 61946X3M 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 (230 mm bore side) ensures perfect planar contact without edge binding.
Built for demanding industrial environments, the 61946X3M Deep Groove Ball 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.
