Industrial Shock Absorbers
An industrial shock absorber decelerates a moving mass over a defined stroke instead of letting it run into a hard stop. It is sized from moving mass, impact velocity, any additional drive force and the number of cycles per hour. The thread size in the designation is the mounting dimension and says nothing about the energy the unit can absorb.
FAQ
Frequently Asked Questions
What data do I need to size one?
Moving mass, impact velocity at the absorber, any additional drive force and the number of strokes per hour. Without the cycle rate the heat dissipation cannot be judged, and that is exactly where an undersized absorber fails in continuous duty.
Self-compensating or adjustable?
Self-compensating units cover a range of masses without readjustment and are the right choice where the load varies in service. Adjustable units achieve smoother deceleration at a constant load, but have to be set once.
How do I recognise a worn absorber?
By leaking oil, by a piston rod that no longer extends fully, and by a noticeably hard stop at the end of the stroke. An industrial shock absorber is replaced, not refilled.
More ranges
Linear Position Transducers
A linear position transducer reports the position of a piston or carriage to the controller as an electrical signal. Two figures drive the selection: the measuring length, which has to cover the usable stroke, and the output signal the controller expects. Both are encoded in the type designation and repeated in the article technical data.
Flange Pressure Gauges
A flange pressure gauge is fitted into the panel from the front and secured through its front ring. Three figures drive the selection: case diameter, measuring range and connection thread. Choose the range so the normal operating pressure sits around the middle third of the scale, because readings at either end of the scale lose accuracy.
Hydac Pressure Switches
A pressure switch monitors a pressure and switches once a set value is exceeded or undershot. On the electronic EDS series, pressure range, output type and electrical connection are specified separately. A range chosen too wide costs resolution exactly where the working point sits.
Reducing Fittings
A reducing fitting sits between two threads of different size, one in the component and one on the line. Check thread form and nominal size separately, because parallel G threads and tapered NPT threads are not interchangeable. If one side is wrong, assembly fails or the joint leaks under operating pressure.
