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

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.

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.

What are the classifications of outer spherical bearings?

What are the classifications of outer spherical bearings?

The code names of spherical ball bearings with top wire are: UC200 series (light series), UC300 series (heavy-duty series), and the deformed product UB(SB)200 series. If the use environment is suitable for a small environment, generally choose the UC200 series, and vice versa. Then choose UC300 series. Usually there are two jackscrews on the outer spherical ball bearing, and the included angle is 120°. Its characteristic is that when cooperating with the shaft, the jackscrew is used to push against the shaft, and then it has a fixing effect, but its cooperation Environmental requirements necessitate small oscillations. This kind of outer spherical ball bearing is relatively common and widely used in various manufacturing industries such as textile machinery and ceramic machinery.

Radial Clearance Adjustment Method of Cylindrical Roller Bearings

Radial Clearance Adjustment Method of Cylindrical Roller Bearings

For the multi-oil wedge tilting bearing pad, it is not allowed to repair the scraping pad, and the pad should be replaced if the gap is not suitable. For tiles with adjustable thickness, the amount of tiles can be adjusted by adding a stainless steel pad under the adjustment block behind the tile, or by thinning the thickness of the adjustment block. Note that for multi-oil wedge tilting bearing pads, the thickness error between pads in the same group should be less than 0.01mm.
