Types of deep groove ball bearings

Deep groove ball bearings are mainly used to bear radial loads, but are also commonly used to bear combined radial and axial loads. Especially when the rotation speed of mechanical equipment is very high and it is not suitable to use thrust bearings, this bearing can be used to bear two-way pure axial load and does not require maintenance during operation. It is a low-priced and widely used bearing. The models of deep groove ball bearings include: deep groove ball bearings (60000 type); deep groove ball bearings with stop grooves on the outer ring (60000N type); deep groove ball bearings with a dust cover on one side and a stop groove on the outer ring on the other side. Bearing (60000-ZN type); deep groove ball bearing with dust cover on both sides and stop groove in the outer ring (60000-2ZN type);

Performance Characteristics and Advantages of Deep Groove Ball Bearings

Deep groove ball bearing is the most representative rolling bearing, which is widely used. It is suitable for operation at high speed or even extremely high speed, and it is very durable without regular maintenance. This type of bearing has small friction coefficient, high limit speed, simple structure, low manufacturing cost and high manufacturing accuracy.

Purpose and method of bearing lubrication

The lubrication methods of bearings are divided into grease lubrication and oil lubrication. In order to give full play to the function of the bearing, first of all, it is necessary to select the lubrication method suitable for the use conditions and purposes. If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease lubrication has the advantage of simplifying the structure around the bearing, comparing the advantages and disadvantages of grease lubrication and oil lubrication.

How to install spherical roller bearings

Spherical roller bearings are equipped with drum-shaped rollers between an inner ring with two raceways and an outer ring with a spherical raceway. The center of curvature of the outer ring raceway surface is consistent with the center of the bearing, so it has the same alignment function as a self-aligning ball bearing. When the shaft or shell deflects, the load and axial load in two directions can be automatically adjusted. It has large radial load capacity and is suitable for situations with heavy loads and impact loads. Bearings with a tapered bore in the inner ring can be installed directly. Or use an adapter sleeve or disassembly barrel to install it on the cylindrical shaft. The cage uses steel plate stamping cage, polyamide forming cage and copper alloy machined cage.
