061.25.1120.301.11.1523 1278 mm 1183 mm 1013 mm 79 mm 1057 mm Frequently Asked Questions about 061.25.1120.301.11.1523 Four-Point Contact Ball Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The Open Type engineered for 061.25.1120.301.11.1523 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 061.25.1120.301.11.1523 Four-Point Contact Ball Slewing Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 1013 mm bore. For the 1278 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Each 061.25.1120.301.11.1523 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (1013 mm bore side) ensures perfect planar contact without edge binding.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing 061.25.1120.301.11.1523 correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
