61852M 320 mm 260 mm 28 mm Frequently Asked Questions about 61852M Deep Groove Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The Open engineered for 61852M 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 61852M Deep Groove Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 61852M, FAG 61852M, NSK 61852M. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Quality starts with raw material selection: CHG Bearing crafts 61852M inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing 61852M correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
