Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for N1040, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
The Open Type engineered for N1040 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies N1040 with a precision bore diameter (d) of 200 mm, an outside diameter (D) of 310 mm, and a nominal ring width (B) of 51 mm. This configuration yields an effective cross-sectional wall thickness of 55.0 mm and an envelope ratio (D/d) of 1.55, delivering compact rigidity for OEM machinery housings.
To match diverse operational dynamics, CHG Bearing supplies N1040 with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
