Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for VA140188, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
When fitting VA140188 over a 135 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies VA140188 with a precision bore diameter (d) of 135 mm, an outside diameter (D) of 252 mm, and a nominal ring width (B) of 35 mm. This configuration yields an effective cross-sectional wall thickness of 58.5 mm and an envelope ratio (D/d) of 1.87, delivering compact rigidity for OEM machinery housings.
Quality starts with raw material selection: CHG Bearing crafts VA140188 inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
