Turntable Bearing is a large bearing that can bear large loads such as axial load, radial load and overturning moment at the same time. It integrates various functions such as support, rotation, transmission and fixing. In general, because of its mounting hole, lubrication and sealing device, can meet the different needs of various kinds of working conditions of the host; on the other hand, the turntable bearing has the advantages of compact structure, convenient installation and convenient rotary guide, easy maintenance and other characteristics, is widely used in hoisting and conveying machinery mining, machine, construction machinery, port machinery, wind power generation, medical equipment, radar and missile launchers and other large rotary device.
Turntable bearings are usually composed of four parts, such as inner ring, outer ring, rolling body, isolation block and so on. As the core components are revolving support, the axial force and radial force can be supported at the same time. There are many forms, but the composition of the structure is basically the same.

Hotowell Manufacturers 3 Way Hydraulic Water Ball Valve(HTW-EG) are used to control the on/off of heat/cool water air-conditioning system pipe to control the room temperature. Â The valve is driven by synchronous motor. Â The motor connects with room thermostats by the terminal of common, open and close. Â By sampling and dealing with the site data, the thermostats send control signal to open/close the motor of ball valve. Â Then the heat/cool water enters into fan coil unit to supply the heat or cool air. Â When the room temperature reaches the set-point, thermostat will send a signal to cut off the ball valve and make it on the best status. Then the room temperature will keep in the comfortable range.

Turntable bearings are usually composed of four parts, such as inner ring, outer ring, rolling body, isolation block and so on. As the core components are revolving support, the axial force and radial force can be supported at the same time. There are many forms, but the composition of the structure is basically the same.
The single row four point contact ball turntable bearing consists of four parts: inner ring, outer ring, steel ball and isolation block. It has compact structure, light weight, four point contact between steel ball and arc raceway, and it can bear axial force and radial force at the same time. The rotary conveyer, the welding machine, the small and medium crane and the excavator can be selected.
The double volleyball turntable bearing has three seat rings. The steel ball and the isolating block can be directly discharged into the upper and lower raceway. According to the force condition, the upper and lower two rows of steel balls with different diameters are arranged. This open assembly is very convenient, upper and lower arc raceway bearing angle is 90 degrees, can bear large axial force and overturning moment. When the radial force is more than 0.1 times the axial force, the raceway must be specially designed. The axial and radial dimensions of the double row different diameter ball bearings are large and the structure is fastened. It is especially suitable for the loading and unloading machinery of the tower cranes, car cranes, etc., which require the diameter of the medium or above.
Single row Cross Roller Slewing Bearing, consisting of two seats, compact structure, light weight, high manufacturing precision, assembly gap is small, the installation of high precision roller for 1:1 cross arrangement, can withstand the axial force, overturning moment and large radial force, is widely used in hoisting and transportation. Engineering machinery and military products.
The three row roller bearing has three seat rings, the upper and lower and the radial raceways separate separately, so that the load of each row of roller can be determined exactly. At the same time can withstand all kinds of load bearing capacity of four kinds of products in one of the largest, the axial and radial dimensions are larger, firm structure, especially suitable for heavy machinery with larger diameter, such as bucket wheel excavators, wheeled crane, crane, port crane, steel water table and large tonnage truck cranes.
The light turntable bearing has the same structural form as the ordinary rotary bearing. It is light in weight and flexible in rotation. It is widely used in the fields of food machinery, filling machinery, environmental protection machinery and so on.
The single row four point contact ball bearing is composed of two seat rings, and the structure is compact, and the steel ball is in contact with the circular arc raceway at four points. It is mainly used for truck cranes, tower cranes, excavators, piling machines, engineering operation vehicles, radar scanning equipment and so on.
