SWL screw jack can be optionally equipped with a protective cover. However, during actual selection, most customers did not choose a protective cover. It may be due to cost-saving reasons, or there may be no choice due to other reasons.

Today Lude Transmission will take you to know about the protective cover, which is not only applicable to SWL screw jacks, but also to other types of screw jacks.

We divide the protective cover into two types, which are installed in the upper area A and the lower area B of the screw jack (see the picture below).

The screw rod part that is constantly telescopic and moving uses a soft protective sleeve, also called a bellows boot. The bellow boot can expand and contract with the expansion and contraction of the screw rod, so that it is not easy to cause damage to the protective cover. Just install the protective pipe on the lower part as a protective cover. Divided into cylindrical type and square tube type.

What if it is a nut movement screw jack? The nut movement can also be fitted with a dust cover. Just install a bellows above and below the nut.

The protective cover plays a very important role in protecting against dust, oil, corrosion, etc. If you have enough budget, it is still recommended to choose a protective tube and dust cover.
