Find key technical answers regarding dimensions, specifications, and replacement options for this model.
For international ocean and air freight, CHG Bearing packs 37040X3 with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
Standard batches of CHG Bearing 37040X3 conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
To match diverse operational dynamics, CHG Bearing supplies 37040X3 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 37040X3 with a precision bore diameter (d) of 200 mm, an outside diameter (D) of 311 mm, and a nominal ring width (B) of 86 mm. This configuration yields an effective cross-sectional wall thickness of 55.5 mm and an envelope ratio (D/d) of 1.55, delivering compact rigidity for OEM machinery housings.
