BT2B 332626/HA7 820 mm 560 mm Frequently Asked Questions about BT2B 332626/HA7 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
For international ocean and air freight, CHG Bearing packs BT2B 332626/HA7 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies BT2B 332626/HA7 with a precision bore diameter (d) of 560 mm, an outside diameter (D) of 820 mm, and a nominal ring width (B) of 242 mm. This configuration yields an effective cross-sectional wall thickness of 130.0 mm and an envelope ratio (D/d) of 1.46, delivering compact rigidity for OEM machinery housings.
To match diverse operational dynamics, CHG Bearing supplies BT2B 332626/HA7 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.
To ensure optimum performance of CHG Bearing BT2B 332626/HA7 Double Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 560 mm bore. For the 820 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
