Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing 5617/620 is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
To safeguard CHG Bearing 5617/620 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (620 mm x 780 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Engineered according to international ISO boundary plans, CHG Bearing supplies 5617/620 with a precision bore diameter (d) of 620 mm, an outside diameter (D) of 780 mm, and a nominal ring width (B) of mm. This configuration yields an effective cross-sectional wall thickness of 0 mm and an envelope ratio (D/d) of 0, delivering compact rigidity for OEM machinery housings.
For international ocean and air freight, CHG Bearing packs 5617/620 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.
