The SKF gear coupling is a very high-torque ratings, along with unparalleled bore capacities, give this coupling a great advantage over other types of couplings. The gear coupling are rated up to 1 310 kNm with a maximum bore of 525 mm. This is a heavy duty coupling with incredible design flexibility, making it an economical choice for many applications. The unique design of the gear coupling tooth crowning dramatically reduces backlash and radial clearance. The hub bore capacities are the largest in the industry, allowing for low cost and long service life.
