Shock Absorbers

BC2 Series Shock Absorber Options

Tolomatic BC2 Series band cylinders come with standard internal cushions (except for the BC205 which has end bumpers) that offer an effective method for decelerating loads. The BC2 cylinders are also capable of carrying heavier loads at higher velocities than the cylinder cushion can absorb. Optional shock absorbers can be used to increase the cylinder's life and broaden the application range for the cylinder model you have chosen.

Shock absorbers offer these advantages:

  • Increases operating speed
  • Smoother deceleration
  • Self-compensates for load changes
  • Minimizes shock load to equipment
  • Reduces equipment maintenance
  • Higher equipment productivity

Two styles of shock absorbers are available for BC2 cylinders. Standard style shocks which are positioned on the cylinder heads for end-of-stroke deceleration and adjustable position shocks that can be placed at any point along the cylinder tube.

CAUTION: In applications which result in a load bending moment at deceleration, care should be taken to decelerate the load rather than the cylinder's carrier. Typical shock absorber life varies between 1-2 million cycles (depending on environment) and appropriate preventative maintenance should be considered in high cyclic applications.

Shock absorbers are configurated per cylinder head. For a cylinder with a shock absorber at each end, order a quantity of "2". Cylinders specified with single shocks will be mounted on the right cylinder head side (as the ports face you).

NOTE: When 2 external / adjustable shock absorbers are ordered, the unit will be assembled with NO internal cushions.

Standard end-of-stroke shock absorbers are designed to operate without the assistance of the standard band cylinder cushion. To ensure proper shock absorber performance, make sure the air cushion is disabled.
