51118 Thrust Ball Bearing

Advantage of 51118 Bearing

Application scope of thrust ball bearing:

It is only applicable to the parts bearing one side of axial load and low speed, such as crane hook, vertical water pump, vertical centrifuge, Jack, low-speed reducer, etc.

The shaft ring, seat ring and rolling element of the bearing are separated and can be installed and disassembled separately.

Type

In addition, the bearing can bear axial load, but can not bear radial load.Composition of thrust ball bearing: the thrust ball bearing is composed of seat ring, shaft ring and steel ball cage assembly. The shaft ring matched with the shaft and the seat ring matched with the housing. According to the stress conditions, it is divided into one-way thrust ball bearing and two-way thrust ball bearing.

Unidirectional thrust ball bearing can bear unidirectional axial load.

Bidirectional thrust ball bearing can bear bidirectional axial load, in which the shaft ring is matched with the shaft.

Basic knowledge

The connection line between the steel ball of the angular contact ball bearing and the contact point of the inner and outer rings forms an angle with the radial direction. Contact angles are generally divided into 15°, 30°, and 40°, which are represented by the letters C, A, and B, respectively.

Angular contact ball bearings can bear radial load and axial load at the same time, (one-way angular contact bearing can only bear axial load in one direction, when bearing radial load, additional axial force will be caused) The greater the load capacity.

High-precision and high-speed bearings typically have a 15-degree contact angle.

Cage material: steel plate, brass or engineering plastic, the molding method is stamping or turning, which is selected according to the bearing form or use conditions.
