BT2B 332547/HA1 673.1 mm 501.65 mm Frequently Asked Questions about BT2B 332547/HA1 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, 100% of BT2B 332547/HA1 Double Row Tapered Roller Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
Engineered according to international ISO boundary plans, CHG Bearing supplies BT2B 332547/HA1 with a precision bore diameter (d) of 501.65 mm, an outside diameter (D) of 673.1 mm, and a nominal ring width (B) of 184.15 mm. This configuration yields an effective cross-sectional wall thickness of 85.7 mm and an envelope ratio (D/d) of 1.34, delivering compact rigidity for OEM machinery housings.
The Open Type engineered for BT2B 332547/HA1 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
The CHG Bearing BT2B 332547/HA1 is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
