Because the contact surface is larger, the surface pressure is smaller, and the flexible shaft or other materials, such as aluminum alloy, carbon fiber, etc., one of the advantages of sliding bearing is further weight reduction.
Since there is no mechanical rolling of hard conflict parts, and there is no collision between rolling bodies, the noise and sensation caused by sliding operation will be less.
Using linear sliding bearing, the guide rail can be spliced, and then it can easily form a longer travel, because the movement of the sliding element is easier to pass through the rail joint than rolling.
In all ball bearings, an important material related downwind is the constraint of allowable speed and acceleration, and the maximum value is limited, especially at low load.
In contrast, the sliding bearing made of engineering plastics has higher sliding speed and acceleration, which greatly improves its cycle time in many applications. But the most important factor is their service life. Bearings made of high-performance engineering plastics are usually more durable than traditional ball bearings.
In addition, its service life can be calculated by various procedures. In the past few years, great progress has been made in accuracy and conflict values. Engineering plastic sliding bearings have been used in many fields of traditional ball bearings.
