Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing 50.8*105 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces ( mm x mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Absolutely. The CHG Bearing 50.8*105 Cylindrical Rollers is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 50.8*105, FAG 50.8*105, NSK 50.8*105. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
To match diverse operational dynamics, CHG Bearing supplies 50.8*105 with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
For international ocean and air freight, CHG Bearing packs 50.8*105 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.
