NU2226/P5 230 mm 130 mm 64 mm 156 mm Frequently Asked Questions about NU2226/P5 Single Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing NU2226/P5 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (130 mm x 230 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 NU2226/P5 Single Row Cylindrical Roller 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 230 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for NU2226/P5. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing NU2226/P5 correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
