Features and Uses Single-acting Thin Jacks

Posted on

Single acting thin jack features
(1) Lightweight and compact design can be used for smaller space operations.
(2) Single-acting oil circuit, spring return.
(3) The piston rod is chrome-plated. Then it is formed by cylindrical grinding. There is a groove at the top. During the lifting process, the friction force can be increased to ensure that the object will not slip off during the lifting process.
Thin Jack How to use
1, before use must check whether the various departments are normal.
2. The rules in the main parameters shall be strictly observed during use, and shall not be overloaded. Otherwise, if the lifting height or lifting tonnage exceeds the specified limit, a serious oil leakage will occur at the top of the fuel tank.
3. If the oil volume of the manual pump body is insufficient, it is necessary to add N33# hydraulic oil, which has been fully filtered, to the pump before it can work.
4, electric pump, please refer to the manual of the electric pump.
5. The center of gravity should be moderate, and the jacking point of the jack should be reasonably selected. The bottom should be flattened. At the same time, the soft and hard conditions on the ground should be taken into account. Whether to put tough wood or not, and whether it is placed in a stable manner, avoid falling or tilting.
6. After the jack has lifted the heavy object, the heavy object shall be firmly supported with the support in time, and the jack shall not be used as a support. If you need to support heavy loads for a long time, please use CLL self-locking jacks.
7. If several jacks need to be lifted at the same time, in addition to the correct placement of the jacks, multiple top diverter valves should be used, and the load of each jack should be balanced, taking care to keep the lifting speed synchronized. It is also necessary to take into account the possibility of sagging due to the uneven weight of the ground and to prevent the risk of tilting the lifter.
8. When using, firstly connect the quick joint of the hand pump to the top, then select the position, and screw the oil drain screw on the oil pump to work. To lower the piston rod, loosen the hand pump manually counter-clockwise and the cylinder is unloaded and the piston rod is gradually lowered. Otherwise it will be dangerous to drop too fast.
9, the jack is a spring return structure, after lifting, you can quickly remove, but can not use the connecting hose to pull the jack.
10, due to small lifting jack travel, users must not exceed the rated travel time, so as not to damage the jack.
11, the use of the process should avoid severe vibration jack.
12. It is not suitable for use in workplaces with acids, alkalis and corrosive gases.
13, the user should regularly check and maintain according to the use
Precautions:
The thin jack is a separate hydraulic jack, so pay attention to the use of the hydraulic system.
1. If there is a phenomenon of idle during use, you can first loosen the oil drain screw on the pump body, turn the pump body vertically up and down a few times, then tighten the oil drain screw and continue to use it.
2. When using, it is not allowed to add partial load or overload to avoid danger of jack damage. When there is a load, do not remove the quick connector to avoid accidents and damage to the parts.
3. The machine uses oil as the medium. The maintenance of the oil and the machine must be done to avoid blocking or oil leakage and affect the use effect.
4. New or long-term hydraulic jacks, because there is more air in the cylinder, the piston rod may appear tiny jump phenomenon when it is used, and the hydraulic jack can be reciprocated 2-3 times to eliminate The air in the cavity. Long idle jacks, due to the seal does not work for a long time caused by the hardening of the seal, thereby affecting the service life of the hydraulic jack, so when the hydraulic jack is not in use, the monthly hydraulic jack reciprocating 2-3 times .
5. The high-pressure fuel pipe passes the 105Mpa (1050Kgf/cm2) test when it leaves the factory. However, because hoses are prone to ageing, users need to check them frequently, usually for six months, and frequent users for three months. When testing, use 87.5Mpa (875Kgf/cm2) pressure test. If there are explosions, projections, leakage, etc., it cannot be used.
6. Strictly observe the technical specifications when operating, and the user should regularly check and maintain it according to the use conditions.

Tapered Roller Bearings

Tapered roller bearings are used in a variety of industrial applications. The tapered rollers allow the bearings to accommodate heavy radial, axial and combination loads. This loading flexibility combined with a variety of configurations can be designed from single cups, double cups, and cones. This is why tapered roller bearings are designed into almost every industry, particularly large diameter tapered roller bearings.

Tapered roller bearings are uniquely designed to manage both thrust and radial loads. Consisting of a "tapered cup" and a "tapered cone", this design is one of the most basic and common styles in the bearing industry. Found in everything from cars to conveyor lines, tapered roller bearings are more versatile than any other bearing series. Our taper bearings are sold in sets with both the cup and the cone together.

tapered roller bearings are designed for the most demanding applications in industries such as mining, forestry and steel manufacturing. Utilizing conical rollers and raceways arranged so that the rollers and raceways meet at a common apex, NTN`s tapered Roller Bearing rollers are guided by contact between the large end of the roller, providing high capacity for radial and single thrust loads. With almost 100 million tapered roller bearings manufactured every year under the NTN and Bower brands, it`s no wonder that NTN rivals all major competitors on the market.

We offer premium tapered roller bearings under the NTN and Bower® brand names. Most NTN and all Bower® tapered roller bearings feature case-carburized components. Cups, cones, and rollers are made from case-hardened alloy steel of [Bearing Quality" to provide superior fatigue life and reliability. Precise control of heat treatment, dimensions, and surface finish of the components further contribute to reliable bearing performance. So whether you`re looking for an American-made, case-carburized inch series taper, or a metric series through-hardened variety, we have you covered with a proper fit for your application. Premium steels and heat treatments are also available for applications requiring extended life and high reliability.
