Thrust ball bearings can form a very compact axial bearing arrangement. Such bearings can withstand heavy axial loads, are insensitive to impact loads, and have good strength. The screw-fixed taking constitutes a specially designed one-way tapered roller thrust bearing. This type of bearing is used in rolling mill screw fixed bearing arrangements. The thrust ball bearing has a logarithmic contact profile between the raceway and the roller to ensure the best stress distribution in the bearing, thereby extending the bearing life.

Thrust ball bearings are only suitable for parts that bear the axial load on one side and have low speed, such as crane hooks, vertical water pumps, vertical centrifuges, jacks, low-speed reducers, etc. The shaft ring, seat ring, and rolling element of the bearing are separated and can be assembled and disassembled separately.

Thrust ball bearings with cage are separable design so that two washers and roller and cage thrust components can be easily installed separately. (If you want to know more about cheap ball bearings, please visit our website.) Full roller screw fixed bearings are fixed together by particular positioning parts. There are threaded holes in the washers for lifting bolts. See the following introduction:
First, small one-way thrust tapered roller bearings are almost entirely used in the knuckle bearing configuration of commercial vehicles. This bearing has full rollers and is fixed with a thin steel cover. Most of these bearings are equipped with wear-resistant, oil-resistant nitrile rubber (NBR) friction seals. This bearing uses multi-purpose grease for lifetime lubrication and requires no maintenance. There are many designs; the only difference is the design of the bearing housing race and bearing housing. Larger one-way bearing washers are manufactured differently. Some bearing washers have the same dimensions as the bearing housing ring, while others have different designs. The machines with the same size coaxial and bearing housing raceways have a tapered raceway and a retaining rib. Bearings of this design are often used in applications that need to withstand large axial loads. They are generally used on drilling equipment turntables or crane hooks. This bearing has a cage and is positioned by two washers. The shaft washers of other designed bearings have tapered raceways and positioning ribs, while the bearing housing races are flat. Therefore, the taking of this design can accept the slight eccentricity of the shaft relative to the bearing box hole without adversely affecting the bearing performance. Except for several sizes with full rollers, this bearing has a cage that is concentric with the rollers. (If you want to know more about cheap ball bearings, please visit our website.)
Two-way thrust tapered roller bearings are mainly used in rolling mills with multi-row cylindrical roller bearings. This type of bearing with a flat shaft washer is more popular because it can withstand a slight eccentricity of the shaft with respect to the bearing box bore and a small change in the radial internal clearance used by the radial bearing. A spacer sleeve is arranged between the two bearing housing races. The size of the spacer sleeve allows the roller bearing box cover screws to be fully tightened, and the bearings do not require individual springs for adjustment. Double-direction tapered roller thrust bearings with tapered raceways on the shaft and bearing housing raceways. Generally, it has a higher axial load-bearing capacity than bearings with flat shaft races, and it can position the shaft radially to a certain extent. If the required service life is taken into consideration, a double-row tapered roller bearing with a large contact angle can be used when the load-bearing capacity of this bearing is insufficient. Because the two-way thrust tapered roller bearing is usually installed on the roll journal and the roll bearing box with a loose fit, most bearing shaft races have one or two positioning grooves. This makes it possible to use a key or the like embedded in the positioning groove to prevent the shaft race from rotating on the shaft.

This type of thrust tapered roller bearing must be able to withstand high axial loads and allow angular displacement of the threaded shaft relative to the bearing. Therefore, this type of bearing is usually a full-roller type with large-diameter and extra-long rollers. This bearing has a spherical race. The seat ring may be a shaft seat ring or a bearing box seat ring. In bearings with a spherical shaft race on the roller set between the spherical shaft race and the corresponding concave spherical threaded shaft or pressure baffle, the necessary centering offset will occur. When the bearing case race is spherical, the centering offset is borne by the roller set between the bearing case race and the pressure baffle. The pressure baffle of this bearing is usually supplied with the bearing. (If you want to know more about cheap ball bearings, please visit our website.)
