Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies QJ6040M 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.
Model QJ6040M is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 200 mm) and steep thermal gradients between inner and outer rings.
Sourcing QJ6040M directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Four-Point Contact Ball Bearings.
Beyond standard alloy steel, CHG Bearing can customize the QJ6040M Four-Point Contact 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.
