SKF gear couplings have a very large torque range and a large diameter range. Toothed couplings have a torque of up to 555,000 Nm and a maximum hole of up to 495 mm. The coupling is suitable for difficult operating conditions and since it can be structurally adapted, it becomes an economical choice for many applications. Universal joints , also known as pin and block joints, are commonly used for industrial, off-road and agricultural applications with low to medium torque.
