Industry standard linear motion slide. AMI
ACTRON Manufacturing, Inc. Industry leader in aerospace latching applications. Anodized
Finish applied to an aluminum surface that provides a protective coating to retard the natural oxidation tendency of aluminum and protects the surface from scratches. Almost any color is available. Hard anodize color varies between light gray/green to black.
Note: Anodize can appear slightly different on different alloys of aluminum. Anti-Friction Latchbolt
Latch bolt is equipped with a component to minimize closing force by reducing the friction between the bolt and the strike.
Several ACTRON designs exist: - EZ-Close- Low friction plastic inserts installed at critical areas of bolt.
- Touch Close- Trigger release mechanism installed within bolt. Uses special strike.
- Smooth Cam- Cam mechanism exerts a lever action to retract bolt.

Dead Bolt Latch
Latch consisting of a bolt with no spring-loaded action or bevel and that once fully extended cannot be retracted except by operating a locking device such as a key cylinder or knob (rotating or sliding). This prevents the latch bolt from unlocking due to excessive vibration or forced entry.Deflection
Difference between the loaded and unloaded position of a latch bolt measured at the loading point. Term also used to describe the distance a retainer assembly bends at its mounting point while under load. Deflection
Acceptable level difference between a loaded and unloaded slide in its extended position, measured at the front end of the slide with an evenly distributed load. Detented

Device that holds one section of a slide in a given position until an extending or closing force sufficient to overcome or release the detent is applied. In contrast to positive locking. Door

Maximum load of a vertically mounted pair of slides when extended, using all available mounting positions. The stated load values relate to a minimum 100,000 cycles. A significantly higher load rate is possible with a lower number of cycles. A horizontal installation would considerably reduce the load rate, by up to 75%. ACTRON telescopic slides have a unique "in-line" multiball-track geometry. They are therefore particularly rigid against distortion. This increases durability and dynamic load capacity significantly.
