There are two main types of jack supports. These are screw and rubber models. With their help, the operation of the unit becomes safer due to the fact that the elements ensure the stability of the structure. This allows you to expand the range of work performed and make them more reliable and of high quality.
Let's take a closer look at each of the types.
Rubber
These are the most common supports (heels). They are available in most parts and parts stores and have a wide range of products. The marking of the rubber lining is indicated with the letter K. For the manufacture of the structure of the support thrust bearing, a cord is used, which significantly extends the service life of the product. The advantage of rubber pads is their low price, which makes spare parts for the jack available.
The production of high-quality rubber supports is carried out by such companies as:
- AE&T (China);
- Nussbaum (Germany);
- OMA-Werther (Italy);
- Ravaglioli (Italy);
- Sivik (Russia);
- DARZ CJSC (Russia);
- OJSC "Avtospesoborudovanie" (Pskov, Russia);
- JSC FORMZ (Russia);
- Serpukhov (Russia).
And this is not a complete list of popular manufacturers of accessories for car lifts. Not so long ago, there were also slotted models suitable for bottle jacks.
Screw
Screw feet are an integral part of jacks used to adjust wooden support posts. With their help, it is possible to adjust the height of the structures, which is very convenient in wooden housing construction. For the convenience of work, use adapters.
Also, attachments with screw supports are used in low-rise construction, where wooden structures are used. The units do an excellent job with the assigned tasks, ensure reliable performance of work, and also have improved strength characteristics and increased carrying capacity.
How to do it yourself?
It is not difficult to make a rubber support for a jack with your own hands. To do this, you need to perform a number of actions. Step-by-step instruction:
- the outer and inner diameters of the metal bowl of the tool are measured (it is convenient to use a caliper);
- the depth of the bowl is revealed along the upper tooth;
- a conveyor belt with a thickness of at least 14 mm is taken - a penny will be made from it (for work, you will also need a drill, a knife and a pair of gypsum crowns of different diameters);
- a crown with a smaller diameter is installed on a drill, a depression is made about 8 mm;
- the crown changes, a full cut is made, a cut out circle is obtained;
- using a marker on the heel, the highest point of the jack bowl is marked and marks are placed;
- according to the marks made, cuts are made with a construction knife 8 mm to the end of the inner circle, teeth are cut (for a more convenient trimming, it is recommended to use a vice);
- if there is a protrusion on the jack bowl, a circle of this diameter should be cut out on the resulting rubber pad.

Appointment
The design of any rolling jack includes a metal cup - this is a part of the tool that rests against the body of the machine when it is lifted. Most types of such bowls have several protrusions that are brought under a specially designed place on the car (not available on all brands). When the car is lifted, the metal cup contacts the body, which is why heavy loads are imposed on it. This often leads to scratches or deep dents in the place of the stop.
Due to such defects, the protective layer is damaged, as a result of which, when metal comes into contact with moisture, the ribs of the car will begin to rust.To prevent this, it is imperative to use the rubber support for the rolling jack. The gasket between the metal bowl and the car body significantly reduces the risk of dents, scratches and other defects formed after using the lifting tool.
