NSK extends high load actuator portfolio

NSK has enhanced its range of compact actuators for high load applications in industrial machines. The Toughcarrier series, which adds to the company’s existing Monocarrier MCH family, is a ready-to-install range of linear systems for applications that include machine tools, robotic handling systems, automotive assembly and welding lines, and automated measuring equipment.

In the Toughcarrier series, the linear guide balls have been replaced by cylindrical rollers, delivering considerably greater load capacity and rigidity compared with Monocarrier MCH units. Both parameters have values that are four times superior in the direction of load.

Both types of actuator are signified by their compact design and light weight, while the surface treatment of the slider and rails ensures excellent corrosion protection. In addition, due to the all-in-one approach of integrated ball screw, support bearings and rail, the units are quick to install and are interchangeable with each other.

At the drive end of Toughcarrier units, the ball screw support bearing is fitted with angular contact ball bearings, while deep groove ball bearings feature at the floating end. As a result, the slider runs freely without any backlash.

Supplied as a preassembled machine axis in three basic slider sizes, Toughcarrier units are offered in lengths of 150 to 1380mm, and in a selection of lead variants. The units can be driven either by a timing belt or a motor.
