Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Every production batch of CHG Bearing 47561RJ Four-Point Contact Ball Slewing Bearings 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.
Beyond standard alloy steel, CHG Bearing can customize the 47561RJ Four-Point Contact Ball Slewing Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 47561RJ. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
The Open Type engineered for 47561RJ by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
