High-torque Motors in Radial Pistons or Cam Ring Design
Typical for INA bearings and Components • Cylindrical Roller bearings provide smooth operation with high static and dynamic radial load capacity. • Steel Seals are characterized by low leakage and small press-on force. The sealing force is precisely deterCam curves of a high-torque motor

mined to ensure efficient seals and minimal friction. • Optimally adjusted, low-wear components, such as rolling elements with special coating, are used in high-Torque motors.

High-torque motors – ideal for operations requiring high torques, involving hard stops and abrupt reverse motions. Classic applications include Machines and equipment, agricultural machinery, crushers, feed devices, rolling mills, paper machines and transport facilities for bulk material. Extremely high torques (e.g. 1,400,000 Nm) are achieved under rough operating conditions. High-torque motors replace conventional Gearboxes and motors and typically offer low startup friction and stick-slip free motion at low speeds. The highquality Cylindrical roller bearings, inner rings ground without spiral marks, highprecision locknuts and other components made by INA also contribute to the functional reliability of these strong motors. 4
