1 ToughcarrierTM

1.1 Features

Greatly improved load capacity due to switching of rolling elements to rollers.
Mounting dimensions are compatible with those of the MCH Series, allowing substitution.

 Light weight and compact design

Taking into account part composition and rigidity, the cross sections of the rail and slider are the
same as MCH series.

 Superb rust-preventive ability

Low-temperature chrome plating comes standard.

 All-in-one structure

1) The all-in-one structure integrates a ball screw, a linear guide and a support unit into a single
structure to significantly reduce design time.

2) The bottom and one side of the rail are datum surfaces to facilitate highly accurate installation.
Models with pin holes are also available as standard.

3) Immediate operation after installation and run-in is possible due to pre-packed grease.
4) A wide selection of ball screw leads are available.

 Long-term maintenance-free operation

Use of NSK K1 lubrication unit and grease maintains smooth lubricating performance for long
periods.

 Updated rolling elements

Rollers are installed as rolling elements
for the first time anywhere.
