34FC25168/P5 250 mm 170 mm 192 mm 168 mm Frequently Asked Questions about 34FC25168/P5 Four-Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing 34FC25168/P5 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (170 mm x 250 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Quality starts with raw material selection: CHG Bearing crafts 34FC25168/P5 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.
Absolutely. The CHG Bearing 34FC25168/P5 Four-Row Cylindrical Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 34FC25168/P5, FAG 34FC25168/P5, NSK 34FC25168/P5. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Beyond standard alloy steel, CHG Bearing can customize the 34FC25168/P5 Four-Row Cylindrical 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.
