Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing 61964 Deep Groove Ball Bearings（618 / 619 SERIES） is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 61964, FAG 61964, NSK 61964. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for 61964, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
Engineered according to international ISO boundary plans, CHG Bearing supplies 61964 with a precision bore diameter (d) of 320 mm, an outside diameter (D) of 440 mm, and a nominal ring width (B) of 56 mm. This configuration yields an effective cross-sectional wall thickness of 60.0 mm and an envelope ratio (D/d) of 1.38, delivering compact rigidity for OEM machinery housings.
When fitting 61964 over a 320 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.
