Linear Speed Limiters
Put an end to lids and doors that slam shut or fly open—install these speed limiters for smooth, controlled motion.
A cycle is one rod stroke from extended to compressed and back to extended. Free travel of stroke is the percentage of the stroke that speed limiters move with no resistance, before speed control engages.
Extension speed limiters prevent doors from flying open.

Corrosion-Resistant Linear Speed Limiters
Smoothly open and close doors, lids, and access panels in damp and corrosive environments with these 316 stainless steel speed limiters.
A cycle is one rod stroke from extended to compressed and back to extended. Free travel of stroke is the percentage of the stroke that speed limiters move with no resistance, before speed control engages.
Extension speed limiters prevent doors from flying open.
Compression and extension speed limiters prevent doors from slamming and flying open.

Precise-Control Linear Speed Limiters
Regulate the speed or feed rate of drill presses, milling machines, lathes, and similar devices. These speed limiters have a knob with numbered scale so you can make precise adjustments to the resistance. Insert a rod in the mounting hole in the knob to rotate for adjustments.
A cycle is one rod stroke from extended to compressed and back to the original extended position. Free travel of stroke is 0%, so the entire stroke is speed controlled.
