3806/385.762-2LS 514.35 mm 385.762 mm 317.5 mm Frequently Asked Questions about 3806/385.762-2LS Four-Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 3806/385.762-2LS 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 (385.762 mm bore side) ensures perfect planar contact without edge binding.
Quality starts with raw material selection: CHG Bearing crafts 3806/385.762-2LS inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
Engineered according to international ISO boundary plans, CHG Bearing supplies 3806/385.762-2LS with a precision bore diameter (d) of 385.762 mm, an outside diameter (D) of 514.35 mm, and a nominal ring width (B) of 317.5 mm. This configuration yields an effective cross-sectional wall thickness of 64.3 mm and an envelope ratio (D/d) of 1.33, delivering compact rigidity for OEM machinery housings.
Yes, 100% of 3806/385.762-2LS Four-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.
