61930M 210 mm 150 mm 28 mm Frequently Asked Questions about 61930M Deep Groove Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The Open engineered for 61930M by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
Absolutely. The CHG Bearing 61930M Deep Groove Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 61930M, FAG 61930M, NSK 61930M. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Each 61930M 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 (150 mm bore side) ensures perfect planar contact without edge binding.
Built for demanding industrial environments, the 61930M 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.
