7026 ACDGD/P4A 200 mm 130 mm 33 mm Frequently Asked Questions about 7026 ACDGD/P4A Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As standard production, CHG Bearing subjects 7026 ACDGD/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 7026 ACDGD/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.
To ensure optimum performance of CHG Bearing 7026 ACDGD/P4A Super-precision Angular Contact Ball Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 130 mm bore. For the 200 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Model 7026 ACDGD/P4A is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 130 mm) and steep thermal gradients between inner and outer rings.
