61944 300 mm 220 mm 38 mm Frequently Asked Questions about 61944 Deep Groove Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 61944 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 (220 mm bore side) ensures perfect planar contact without edge binding.
Absolutely. The CHG Bearing 61944 Deep Groove Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 61944, FAG 61944, NSK 61944. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Beyond standard alloy steel, CHG Bearing can customize the 61944 Deep Groove Ball 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.
To extend the trouble-free lifespan of CHG Bearing 61944, 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.
