Accuride's product range includes the DP0115-ECRC, DP0116-ECRC and DP0118RC soft close mechanism for the DA0115RC, DA0116RC and DA0118RC linear slides. This gives you a feature that dampens the thrust during retraction and closes or opens smoothly.
There is no interface kit for the DP0115-ECRC/DP0116-ECRC/DP0118RC to work with other slide systems. However, it is possible to make the soft-slose mechanism compatible with other slide types by designing a corresponding interface yourself.
