010.20.310.03K 385 mm 216 mm 54 mm 259 mm 358 mm Frequently Asked Questions about 010.20.310.03K Four-Point Contact Ball Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
In its sealed configuration (Open Type), CHG Bearing pre-charges 010.20.310.03K with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
When fitting 010.20.310.03K over a 216 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 010.20.310.03K. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
To safeguard CHG Bearing 010.20.310.03K against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (216 mm x 385 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
