61915 105 mm 75 mm 16 mm Frequently Asked Questions about 61915 Deep Groove Ball Bearings（618 / 619 SERIES）
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 61915 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (75 mm bore side) ensures perfect planar contact without edge binding.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 61915. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
The CHG Bearing 61915 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 ensure optimum performance of CHG Bearing 61915 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 75 mm bore. For the 105 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
