787/2625K 2978 mm 2625 mm 114 mm 2691 mm 2910 mm Frequently Asked Questions about 787/2625K Four-Point Contact Ball Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 787/2625K with a precision bore diameter (d) of 2625 mm, an outside diameter (D) of 2978 mm, and a nominal ring width (B) of 114 mm. This configuration yields an effective cross-sectional wall thickness of 176.5 mm and an envelope ratio (D/d) of 1.13, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing 787/2625K 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 2625 mm bore. For the 2978 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Each 787/2625K 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 (2625 mm bore side) ensures perfect planar contact without edge binding.
The Open Type engineered for 787/2625K 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.
