61919 130 mm 95 mm 18 mm Frequently Asked Questions about 61919 Deep Groove Ball Bearings（618 / 619 SERIES）
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 61919 with a precision bore diameter (d) of 95 mm, an outside diameter (D) of 130 mm, and a nominal ring width (B) of 18 mm. This configuration yields an effective cross-sectional wall thickness of 17.5 mm and an envelope ratio (D/d) of 1.37, delivering compact rigidity for OEM machinery housings.
To safeguard CHG Bearing 61919 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (95 mm x 130 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 61919 Deep Groove Ball Bearings（618 / 619 SERIES） under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 95 mm bore. For the 130 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 61919. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
