7mm bearing is a kind of rolling bearing

7mm bearing is a kind of rolling bearing, the spherical alloy steel ball is installed in the middle of the inner ring and the outer ring, in a rolling way to reduce the friction in the process of power transmission and improve the transmission efficiency of mechanical power.7mm bearing cannot withstand large heavy loads and are more common in light industrial machinery.
7mm bearing is generally used in low load mechanical transmission equipment. Because the 7mm bearing area of ball bearings is small, it is easy to cause serious mechanical damage in the case of high speed operation, so needle roller bearings are often used in heavy load mechanical transmission to increase the bearing surface, improve the mechanical transmission efficiency, and reduce mechanical damage,earing with dust cover, suffix 2Z, dust cover is made of stainless steel. The dust cover forms a very narrow gap in the shoulder of the bearing inner ring, and can withstand high temperature environment and high speed environment. All stainless steel material bearing can also acid and alkali resistance, corrosion resistance.
7mm bearing with contact sealing ring, suffix 2RS, the sealing ring is made of oil and wear resistant nitrile rubber with steel skeleton. Ordinary sealing ring allows the working temperature of -40 to +100℃, in a short time can be as high as +120℃, so the high temperature environment is not suitable for stainless steel bearing with sealing ring.
The outer edge of the bearing sealing ring is in the groove of the outer ring. In this position, the stainless steel 7mm bearing can achieve excellent sealing effect and can be used in wet environments such as underwater.
