61876 480 mm 380 mm 46 mm Frequently Asked Questions about 61876 Deep Groove Ball Bearings（618 / 619 SERIES）
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing 61876 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (380 mm x 480 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Quality starts with raw material selection: CHG Bearing crafts 61876 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.
Every production batch of CHG Bearing 61876 Deep Groove Ball Bearings（618 / 619 SERIES） comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
As standard production, CHG Bearing subjects 61876 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.
