The robust scew

The capacity to carry heavy loads for thousands of hours in the most arduous conditions makes SR/BR/TR/PR planetary roller screws suitable for the most demanding applications. The robust nut can withstand shock loads and the timing mechanism ensures reliability even in harsh environments and at high accelerations; the long lead and the symmetrical design of the nut permit high linear speeds.
