618/1000MA 1220 mm 1000 mm 100 mm Frequently Asked Questions about 618/1000MA Deep Groove Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing 618/1000MA against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (1000 mm x 1220 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
For international ocean and air freight, CHG Bearing packs 618/1000MA 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.
The CHG Bearing 618/1000MA 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.
Yes, 100% of 618/1000MA Deep Groove Ball Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
