DS (replaces TLS) Telescopic Linear Guides
The DS Series is a high capacity telescopic rail assembly where the stroke is approximately equal to the overall length of the rail. This series is constructed with cold drawn steel rails that are hardened to provide long life even in equipment with highly repetitive motion. The bearing system consists of large diameter, caged balls. The large balls and hardened steel raceways yield high load capacities and life.
There are three versions available: DSS, DSB, and DSD. The DSS version that is a conventional single stroke system. DSB incorporates a locking system for the closed or retracted position. The DSD is a bidirectional or double stroke system.

The table below is for the DSD Series. It is basically the same as the DSS series but has the capability to stroke in both directions (i.e., bi-directional).
It is sometimes referred to as a double stroke system. Stroke is slightly (i.e., a few millimeters) less than the DSS series.
