7034 ACD/P4ADBA 260 mm 170 mm 84 mm Frequently Asked Questions about 7034 ACD/P4ADBA Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting 7034 ACD/P4ADBA over a 170 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.
Absolutely. The CHG Bearing 7034 ACD/P4ADBA Super-precision Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 7034 ACD/P4ADBA, FAG 7034 ACD/P4ADBA, NSK 7034 ACD/P4ADBA.
