68FC49300/P5 490 mm 340 mm 380 mm 300 mm Frequently Asked Questions about 68FC49300/P5 Four-Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
For international ocean and air freight, CHG Bearing packs 68FC49300/P5 with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
Beyond standard alloy steel, CHG Bearing can customize the 68FC49300/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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 68FC49300/P5 with a precision bore diameter (d) of 340 mm, an outside diameter (D) of 490 mm, and a nominal ring width (B) of 300 mm. This configuration yields an effective cross-sectional wall thickness of 75.0 mm and an envelope ratio (D/d) of 1.44, delivering compact rigidity for OEM machinery housings.
Quality starts with raw material selection: CHG Bearing crafts 68FC49300/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.
