46T2018 180 mm 100 mm Frequently Asked Questions about 46T2018 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 46T2018. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
When fitting 46T2018 over a 100 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.
The CHG Bearing 46T2018 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 46T2018 with a precision bore diameter (d) of 100 mm, an outside diameter (D) of 180 mm, and a nominal ring width (B) of 105 mm. This configuration yields an effective cross-sectional wall thickness of 40.0 mm and an envelope ratio (D/d) of 1.8, delivering compact rigidity for OEM machinery housings.
