Plastic pepper balls are not widely used in slide rails. The main reason is that the price of plastic pepper balls used in slide rails is higher than that of steel balls. Slide rail manufacturers will give priority to using steel balls on slide rails in consideration of cost, but high-grade slide rails are mainly made of plastic pepper balls.

Although the cost of using steel balls on the slide rail is low, the steel balls are easy to rust, and the steel balls need lubricating oil for lubrication, which is the original picture that the new steel ball slide rail is easy to use, and the slide rail will be stuck after being used for more than one year. After the slide rail oil on the slide rail is not consumed, the steel balls will rust and the slide rail will not be smooth.

Although the cost of using plastic pepper balls on the slide rail is high, the plastic pepper balls have self-lubricating performance and do not need to be lubricated with lubricating oil, so the service life of using plastic pepper balls on the slide rail will be longer. Another advantage of using plastic pepper balls on the slide rail is that the slide rail will not produce noise when working, because the plastic pepper balls have certain elasticity and can absorb vibration and noise. In the long run, more and more plastic pepper balls will be used on the slide rail.
