Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Sourcing 7205 CDGA/HCP4A directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Super-precision Angular Contact Ball Bearings.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for 7205 CDGA/HCP4A, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
When fitting 7205 CDGA/HCP4A over a 25 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 7205 CDGA/HCP4A with a precision bore diameter (d) of 25 mm, an outside diameter (D) of 52 mm, and a nominal ring width (B) of 15 mm. This configuration yields an effective cross-sectional wall thickness of 13.5 mm and an envelope ratio (D/d) of 2.08, delivering compact rigidity for OEM machinery housings.
