As one of the most commonly used accessories of furniture, the quality of the sliding rail directly affects the service life of furniture. At present, most of the sliding rails on furniture use steel ball and pepper ball as the sliding shaft, and the pepper ball on the sliding rail is actually more advantageous than the steel ball on the sliding rail.The slide rail pepper ball is made of plastic POM material, also called Saigang, which has high strength and can fully meet the load-bearing requirements of the slide rail during use.The slide rail pepper ball will not rust, POM material itself has the physical properties of self-lubrication, and it can always keep a smooth sliding state without adding lubricating oil during use.The pepper ball on the slide rail has a certain elasticity, so there will be no great abnormal sound during the work of the slide rail, and the effect of silence is always maintained.The following details the characteristics of the steel ball of the slide rail:1. The steel ball of the slide rail is low in cost and cheap, but it is easy to rust during use. Of course, stainless steel balls can also be used as the slide rail balls, but the cost of stainless steel balls is higher, which is several times more than the price of ordinary steel balls.2. The steel ball of the slide rail needs to be filled with lubricating oil frequently. If the lubricating oil is insufficient, the steel ball will rust and the slide rail will be stuck. Hard work may even damage the furniture.3. The steel ball of the slide rail will produce noise, because the contact part between the slide rail and the steel ball is also iron, and the steel ball is also iron, so the rubbing between iron and iron will produce abnormal sound and noise
