Hello. This is SGO .

Today, we are going to talk about the main uses of oilless bearings made by SGO.

​

Bearings are widely applied throughout the machinery industry as mechanical elements that freely move shafts and parts in parallel rotation and reciprocation. That is why bearings, also called 'rice in the machinery industry', occupy an indispensable and very important position.

Oilless bearing is in the material type and shape, the sliding movement direction, but in accordance with Where Used be divided into hundreds, large powder metallurgy (Powder Metallurgy) used to absorb the lubricant to the porous metal material is made of " small defect type Oilless bearings and solid lubricants containing various components such as graphite and Teflon can be divided into'embedded oilless bearings ', which are used with metal materials such as high-strength brass and cast iron .

SGO directly produces, manufactures and sells oilless bearings with special materials such as'resin coated oilless bearings' and'bimetal oilless bearings' as well as the two types of oilless bearings described. It is a professional company .

​

The main applications of oilless bearings will be explained together with the sliding motion of oilless bearings.

The motion patterns that appear in sliding bearings including oilless bearings can be classified into four broad categories as follows.

​

1. Linear direction

Linear reciprocating motion in parallel in the longitudinal direction of the shaft. Mainly used as a slider part of a press machine

2. Direction of rotation

A form that performs rotational motion in a direction perpendicular to the longitudinal direction of the axis. Used as parts of hydraulic cylinders such as arms, booms, and buckets of excavators

3. Linear / rotational direction

A form that moves in parallel in a linear direction and a rotational direction. Used as toggle and clamping parts for injection molding machines

4. No direction

The friction surface of the wear plate is used to move without a certain direction.

Of course, in the actual use environment of oilless bearings, more various types of sliding motion can occur. The material and shape of the oilless bearing, the specification of the solid lubricant, and the conditions for design variables such as oil groove, groove, and dimple are changed according to the described sliding motion type.

​

Most of the applications that have been described so far are  mid- to large-sized industrial machines , which are parts that operate at relatively  high loads and low speeds . However, in addition to these large industrial machines, there  are also oilless bearings that are used as parts for small machines and devices that operate at low and medium speeds . For example, these include  bicycles, computers, copiers, and air compressors that  are in contact with real life. These oilless bearings usually have a very long replacement cycle and are often associated with the life of the product.
