021.60.3150 3428 mm 2872 mm 226 mm 3338 mm 2962 mm Frequently Asked Questions about 021.60.3150 Double-Row Ball Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The Open Type engineered for 021.60.3150 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.
To ensure optimum performance of CHG Bearing 021.60.3150 Double-Row Ball Slewing Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 2872 mm bore. For the 3428 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Built for demanding industrial environments, the 021.60.3150 Double-Row Ball Slewing Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 021.60.3150. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
