FK Series Medium
Fixed Shock Absorber
Bansbachs industrial shock absorbers are a superior alternative to coil springs or rubber bump stops for energy absorption and linear deceleration. We offer many different models from mild to extreme. Our shock absorbers are the perfect solution for a wide range of applications, from a simple cabinet door, to the corrosive environments of the medical field, or the extreme environment of industrial machine equipment. Bansbach shock absorbers are designed to absorb the impact with no bounce back. This steady, gradual deceleration allows faster cycle rates, increased equipment life, and higher production rates while reducing maintenance expenses.

* Do not use this product without carefully reading the attached owner's manual. * Ensure that sufficient mounting strength is secured for this product. (As a guideline, it should be 2 to 3 times the maximum drag listed in the catalogue.) * It cannot absorb impact from both directions at the same time. * Do not use this product in a vacuum or a location where it may come in contact with oil. * Ensure that an eccentric load is not applied to the soft absorber. (Allowable eccentric angle: ±2.5°) * Ensure that an external stopper is also used. |
FA-0805/1005/1008/1210 Video
In this video one of our shock absorbers is being put to the test. During this experiment the shock absorber is bombarded with volatile chemicals and actuated to demonstrate the strength and reliability of Bansbach ® industrial shock absorbers.
| With a fixed, specially-designed orifice structure,
an optimal impact absorption can be achieved
even under variable operating conditions.
(FK-0404 and FK-0604 series have a groove-orifice structure.) Three different types are available to accommodate various speeds. For low-speed: L, for medium-speed: M, for highspeed: H. Urethane cap specification is also available. Two or more of each product can be used in parallel. This product can also be custom-designed for optimal impact absorption. |
