802111 488.95 mm 355.6 mm 317.5 mm Frequently Asked Questions about 802111 Four-Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 802111 with a precision bore diameter (d) of 355.6 mm, an outside diameter (D) of 488.95 mm, and a nominal ring width (B) of 317.5 mm. This configuration yields an effective cross-sectional wall thickness of 66.7 mm and an envelope ratio (D/d) of 1.37, delivering compact rigidity for OEM machinery housings.
Beyond standard alloy steel, CHG Bearing can customize the 802111 Four-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.
The Open Type engineered for 802111 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.
When fitting 802111 over a 355.6 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
