61896P4 600 mm 480 mm 56 mm Frequently Asked Questions about 61896P4 Deep Groove Ball Bearings（618 / 619 SERIES）
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Standard batches of CHG Bearing 61896P4 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.
Quality starts with raw material selection: CHG Bearing crafts 61896P4 inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
To ensure optimum performance of CHG Bearing 61896P4 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 480 mm bore. For the 600 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
As standard production, CHG Bearing subjects 61896P4 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.
