Product Description
Deep groove ball bearing
Our precision deep groove ball bearings are designed for high precision, low noise, small vibration, high reliability and long life. They are mainly used in various types of electric motors.
Deep groove ball bearings are widely used in household appliances, toys, electric power tools, car motors and other fields. With optimal design, high reliability heat treatment, precision manufacturing processes and high-grade grease, these products perform better on reliability, vibration and noise levels than standard products making them more suitable for electric motor applications. These products can also be applied to most gearbox applications as well.
Features:
Deep groove ball bearings are the most common type of rolling bearings. Their use is very widespread. The raceway grooves on both the inner and outer rings have circular arcs of slightly larger radius than that of the balls. In addition to radial loads, axial loads can be imposed in either direction. Because of their low torque, they are highly suitable for applications where high speeds and low power loss are required.
Single row deep groove ball bearings:
Despcriptions:
Single row deep groove ball bearings are the most frequently used type of rolling bearing. They are produced in numerous sizes and designs and are particularly economical.
Sealing:
Open bearings are suitable for high to very high speeds.
Deep groove ball bearings with the suffix 2Z have gap seals on both sides and are suitable for high speeds.
Bearings with the suffix 2RSR have lip seals on both sides made from nitrile butadiene rubber NBR and are suitable for moderate speeds.
By agreement, we can supply bearings with non-contact BRS seals on both sides (suffix 2BRS). These bearings have favourable frictional behaviour equivalent to that of bearings with Z seals . If the inner ring is stationary and the outer ring rotates, the lubricant loss is less than that in bearings with Z seals .
Deep groove ball bearing 6301bearing application:
Mining operations, paper mills, oil fields, marine industry, steel, electrical, construction machinery, various kinds of professional machinery and heavy industry of all types
