Precautions for deep groove ball bearings

Precautions for deep groove ball bearings

For deep groove ball bearings, if the bearing load is too small during operation, sliding will occur between the ball and the raceway, which will cause abrasions. Especially large deep groove ball bearings with high ball and cage weights have this tendency. In many cases, bearings will rust. There are many reasons for bearing rust. The most common factors in our daily life are the following

Installation method of spherical roller bearing

Installation method of spherical roller bearing

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.

The ability of single row tapered roller bearings to withstand axial loads

The ability of single row tapered roller bearings to withstand axial loads

The ability of tapered roller bearings to withstand axial loads depends on the contact angle, that is, the angle of the raceway of the outer ring. The larger the angle, the greater the axial load capacity. The most used tapered roller bearings are single row tapered roller bearings. In the front wheel hub of the car, a small-sized double-row tapered roller bearing is used. Four-row tapered roller bearings are used in heavy machinery such as large cold and hot rolling mills.

Cylindrical roller bearing product features

Cylindrical roller bearing product features

The raceways and rolling elements of cylindrical roller bearings are geometrically shaped. After the improved design, it has higher load-bearing capacity. The new structural design of the rib and roller end face not only improves the axial load-bearing capacity of the bearing, but also improves the lubrication conditions in the contact area between the roller end face and the rib, improving the Bearing performance.

How to disassemble and install outer spherical bearings?

How to disassemble and install outer spherical bearings?

Install the eccentric sleeve. First put the eccentric sleeve on the eccentric step of the inner sleeve of the bearing and tighten it by hand in the direction of rotation of the shaft. Then insert or push the small iron rod into the countersunk hole on the eccentric sleeve. Hit the small iron rod with a hand hammer in the direction of rotation of the shaft. Make sure the eccentric sleeve is installed securely, and finally tighten the hexagon socket screws on the eccentric sleeve.

Functional characteristics of tapered roller bearings

Functional characteristics of tapered roller bearings

The type code of tapered roller bearings is 30000[5], and tapered roller bearings are separate bearings. In general, especially within the size range involved in GB/T307.1-94 "Rolling Bearings Radial Bearing Tolerances", the outer ring and inner components of tapered roller bearings are 100% interchangeable.
