A traction gas spring is different from a conventional gas spring since it is working in the opposite direction, which means that it contracts instead of being pushed out. Unloaded, the piston rod is inside the cylinder while as under load; the force works to pull the rod back into the cylinder. It also has flat progression, which means a relatively even force throughout the stroke, unlike a wire spring where the force increases gradually.
Common applications for traction gas springs are, for example, doors, hatches and lids that open sloping where the function of the gas spring is to retract the door. Traction gas springs can be very useful in a variety of diversified industrial applications.
“We have noticed an increase in demand from the market in recent years and therefore it was just the right time to introduce this product group now. There is a demand from, above all, industrial customers throughout Europe and we are pleased to now be able to supplement our range of gas springs with another in-demand product”, says Greg Lehman, product manager at Lesjöfors Stockholms Fjäder.
STANDARD OR CUSTOMIZED VERSIONS
Technical engineers from Lesjöfors Stockholms Fjäder have led all development of the traction gas springs in close collaboration with the group’s producing units in South Korea and Latvia. After the summer, Lesjöfors in Latvia will provide a warehouse for the complete standard gas spring range, including traction gas springs.
“We can already offer standard variants in black-painted carbon steel in a number of dimensions. We can also manufacture customized variants in different dimensions or in stainless steel according to the customer’s individual requirements”, says Greg Lehman.
You can find our standard range of traction gas springs in our digital catalogue.
