7034 CD/P4ADBA 260 mm 170 mm 84 mm Frequently Asked Questions about 7034 CD/P4ADBA Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing 7034 CD/P4ADBA 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.
To safeguard CHG Bearing 7034 CD/P4ADBA against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (170 mm x 260 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
The Open Type engineered for 7034 CD/P4ADBA by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7034 CD/P4ADBA with a precision bore diameter (d) of 170 mm, an outside diameter (D) of 260 mm, and a nominal ring width (B) of 84 mm. This configuration yields an effective cross-sectional wall thickness of 45.0 mm and an envelope ratio (D/d) of 1.53, delivering compact rigidity for OEM machinery housings.
