Zhongshan Rizda Castor Manufacturing Co., Ltd. Located in Zhongshan City, Guangdong Province, one of the central cities of the Pearl River Delta, covering an area of more than 10000 square maters. It is a professional manufacture of wheels and Castors to provide customers with a wide range of sizes, types and styles of products for a variety of applications. The predecessor of the company was BiaoShun Hardware Factory, founded in 2008 which have had 15 years of professional production and manufacturing experience.
Rubber castors have good oxidation resistance and corrosion resistance, which can effectively resist corrosive factors in industrial environment. The castors are soft and can effectively reduce noise in use. The needle roller bearing is a roller bearing with cylindrical rollers. The roller length is 3~10 times of the diameter, and the diameter is generally no more than 5 mm. The transmission efficiency is high. The friction coefficient is only 0.001-0.005;
1. Excellent tensile resistance and highest tensile strength.
2. Long-term temperature resistance exceeds 70 ℃ and low temperature environment performance is good. It can still maintain good bending at - 60 ℃.
3. Good electrical insulation, skid resistance, wear resistance, weather resistance and general chemicals.
4. Soft texture can effectively reduce noise in use.
5. Good dynamic mechanical properties.
6. The rolling bearing has high mechanical performance and long service life.
7. Since the rolling bearing has high transmission efficiency and low heat output, it can reduce the consumption of lubricating oil, and the lubrication and maintenance are more convenient.
