61944M 300 mm 220 mm 38 mm Frequently Asked Questions about 61944M Deep Groove Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The Open engineered for 61944M 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.
To ensure optimum performance of CHG Bearing 61944M Deep Groove Ball Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 220 mm bore. For the 300 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Built for demanding industrial environments, the 61944M 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.
Every production batch of CHG Bearing 61944M Deep Groove Ball Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
