Sourcing QJ218 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.
Each QJ218 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 (90 mm bore side) ensures perfect planar contact without edge binding.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for QJ218. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
Engineered according to international ISO boundary plans, CHG Bearing supplies QJ218 with a precision bore diameter (d) of 90 mm, an outside diameter (D) of 160 mm, and a nominal ring width (B) of 30 mm. This configuration yields an effective cross-sectional wall thickness of 35.0 mm and an envelope ratio (D/d) of 1.78, delivering compact rigidity for OEM machinery housings.
