S7026 ACD/P4A 200 mm 130 mm 33 mm Frequently Asked Questions about S7026 ACD/P4A Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies S7026 ACD/P4A with a precision bore diameter (d) of 130 mm, an outside diameter (D) of 200 mm, and a nominal ring width (B) of 33 mm. This configuration yields an effective cross-sectional wall thickness of 35.0 mm and an envelope ratio (D/d) of 1.54, delivering compact rigidity for OEM machinery housings.
As standard production, CHG Bearing subjects S7026 ACD/P4A to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
To safeguard CHG Bearing S7026 ACD/P4A against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (130 mm x 200 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
The Non-contact Seal engineered for S7026 ACD/P4A 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.
