Couplings


SKF offers a wide range of standard and customised coupling products. SKF Couplings cover a wide range of coupling types, sizes and capacity ratings for many applications and factory environments.

For example, SKF Grid Couplings are an excellent choice for high output (kW) and high torque applications where vibration, shock loads and misalignment occur. SKF Gear Couplings are heavy duty couplings with incredibled design flexibility and are an economical choice for many applications. Very high torque ratings, along with large bore capacities, give this coupling a great advantage over other types of couplings.

For demanding heavy duty applications, SKF has large size couplings. These couplings, can accommodate high torque values, while minimising power loss, and the effects of misalignment.

SKF Flex-, Chain-, FRC-, Jaw couplings and Universal joints are manufactured according to established market standards and are fully interchangeable with other brands: SKF Grid, Gear and Rigid couplings are manufactured according to established industrial standard, which is acceptable throughout the world. SKF Gear couplings are interchangeable, half to half, to industries standard using AGMA bolt pattern. Every coupling is protected by a specific treatment, which depends on the material or type of packaging: (1) phosphate coating, (2) blackening, (3) spray painting or (4) anti-corrosion oil.
