EE91700D/91112 285.75 mm 177.8 mm Frequently Asked Questions about EE91700D/91112 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Every production batch of CHG Bearing EE91700D/91112 Double Row Tapered Roller Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
Engineered according to international ISO boundary plans, CHG Bearing supplies EE91700D/91112 with a precision bore diameter (d) of 177.8 mm, an outside diameter (D) of 285.75 mm, and a nominal ring width (B) of 106.36 mm. This configuration yields an effective cross-sectional wall thickness of 54.0 mm and an envelope ratio (D/d) of 1.61, delivering compact rigidity for OEM machinery housings.
Beyond standard alloy steel, CHG Bearing can customize the EE91700D/91112 Double Row Tapered Roller 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.
Each EE91700D/91112 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 (177.8 mm bore side) ensures perfect planar contact without edge binding.
