61952P4 360 mm 260 mm 46 mm Frequently Asked Questions about 61952P4 Deep Groove Ball Bearings（618 / 619 SERIES）
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To match diverse operational dynamics, CHG Bearing supplies 61952P4 with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
Engineered according to international ISO boundary plans, CHG Bearing supplies 61952P4 with a precision bore diameter (d) of 260 mm, an outside diameter (D) of 360 mm, and a nominal ring width (B) of 46 mm. This configuration yields an effective cross-sectional wall thickness of 50.0 mm and an envelope ratio (D/d) of 1.38, delivering compact rigidity for OEM machinery housings.
When fitting 61952P4 over a 260 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
Standard batches of CHG Bearing 61952P4 conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
