Used on BC2 an BC3 band cylinders to decelerate heavy loads at high velocities. Tol-O-Matic offers light and heavy duty shock absorbers. The sizing and selection software will automatically choose the correct either light duty or heavy duty as required. When shock absorbers are used on the cylinder internal cushions are not operational. Note: Shock absorber is most effective when stopping load at its center of gravity.

Ambient Temperature

The temperature of the cooling medium, usually air, immediately surrounding the actuator or another device.

Anodizing

Protective treatment for aluminum that involves subjecting the metal to electrolytic action in a chemical bath, to create a protective film of aluminum oxide with a very smooth finish.

Auxiliary Carrier

An option for band cylinders or linear slides that increases the load capacity of the cylinder as well as increasing the capacity of bending moment about the Y axis. Note: internal cushion will not work when auxiliary carrier ordered without piston, it will be necessary to add external shock absorbers.

Average Velocity

Velocity calculations for all rodless cylinders need to differentiate between final velocity and average velocity. For example: Cycling a 100 inch BC3 model in one direction in one second yields an average velocity of 100 inches per second. To properly determine the inertia forces for cushioning, it is important to know the final (or impact) velocity. Rodless cylinders accelerate and decelerate at each end of the stroke. Therefore this acceleration must be considered. If final velocity cannot be calculated directly, a reasonable guideline is to use 2X average velocity.

Axial Loading

A load with a force directed along an axis, such as a shaft.
