EE221026/221576D 400.05 mm 260.35 mm 155.575 mm Frequently Asked Questions about EE221026/221576D Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Quality starts with raw material selection: CHG Bearing crafts EE221026/221576D 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.
To safeguard CHG Bearing EE221026/221576D against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (260.35 mm x 400.05 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
