Frequently Asked Questions about HJB050XP4 Thin Section Four-Point Contact Ball Bearings

Find key technical answers regarding dimensions, specifications, and replacement options for this model.

As standard production, CHG Bearing subjects HJB050XP4 to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
For international ocean and air freight, CHG Bearing packs HJB050XP4 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.
Beyond standard alloy steel, CHG Bearing can customize the HJB050XP4 Thin Section 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies HJB050XP4 with a precision bore diameter (d) of 127 mm, an outside diameter (D) of 142.875 mm, and a nominal ring width (B) of 7.9375 mm. This configuration yields an effective cross-sectional wall thickness of 7.9 mm and an envelope ratio (D/d) of 1.12, delivering compact rigidity for OEM machinery housings.
