10%–30% more compact ball nut
The outside diameter of the ball nut is as much as 30% smaller than those of conventional NSK products. This contributes to a more compact design for all sorts of equipment and devices such as thinner XY tables.
High-speed operation of up to 5000 min-1
The new ball screws offer 1.6 times faster rotational speed than conventional ball screws. They handle speeds up to 5000 min-1. This capability dramatically expands the range of service conditions. Note: Please refer to the dimension table for details of permissible rotational speed.
New type of contact seal
A new high-performance contact seal minimizes grease dispersion and helps to maintain a clean work environment.
Extended product life
K1™ Lubrication Units, in combination with minimal grease, offer increased product life and maintenance-free operation.
