Many bathroom sliding door rollers use nylon coats on the outside, but the bearings are different. The bearing is an very important apart for bathroom sliding door roller, bacause the high quality bearing will have longer service life. At present, there are many material of bearing: copper, carbon steel, zinc alloy, and stainless steel bearings in the market. After testing, we think the 304 stainless steel bearing wheel is the best choice, followed by copper material.
(1)304 stainless steel bearing wheel: After 100,000 continuous and destructive tests, there is no damage and its service life is more than 5 years, it can prevent wear and bearing oil leakage effectively.The outer wheel are made by nylon, high temperature and durability resistance, and has an avoiding dropper with a soft closing mechanism to ensure sliding smoothly and safely of the bathroom.
(2)Copper bearing with rubber wheel: This is the most common roller bearing. The middle part is copper with stainless steel ball bearing inside and white plastic wheel outside. The copper and plastic is soft and fragile, so they are easy to be wear when stainless steel boll bearing working. That will be a reason that resulting large pulley gaps and degumming.
(3)Carbon steel wheel: If a wheel made by iron-carbon alloy with less than 2% carbon content in a little silicon, manganese, phosphorus, sulfur and other impurities.This material of sliding wheel has high hardness, but it is also fragile and easy to be rusty, and short service life.
