Plastic thrust ball bearing 51100, mainly purchased from POM material for production.

Product features: It has characteristics such as cold resistance, wear resistance, corrosion resistance, magnetic and electrical insulation resistance, oil-free self-lubricating, and high speed. Application areas: medical devices, low-temperature engineering food processing machinery, optical instruments, chemical industry, cleaning equipment, printing machinery, electroplating equipment, PCB board equipment, etc. Product details: Thrust ball bearing composition: The thrust ball bearing consists of three parts: the seat ring, the shaft ring, and the steel ball cage assembly. A weighing ring that matches with the shaft and a weighing ring that matches with the housing. Divided into unidirectional thrust ball bearings and bidirectional thrust ball bearings according to the force situation. Unidirectional thrust ball bearings can withstand unidirectional axial loads. Bidirectional thrust ball bearings can withstand bidirectional axial loads, where the shaft ring is matched with the shaft. The installation surface of the seat ring is a spherical bearing with self-aligning performance, which can reduce the impact of installation errors. Thrust ball bearings cannot withstand radial loads and have a lower limit speed. . The installation of thrust bearings is generally a transitional fit between the ring and shaft of the thrust bearing, and a clearance fit between the seat ring and the bearing seat hole. Therefore, this type of bearing is easier to install. The central axis of the bidirectional thrust bearing should be fixed on the shaft to prevent relative rotation.



The installation method of plastic thrust ball bearings is generally in the case of shaft rotation, so the fit between the inner ring and the shaft is an over win fit, and the fit between the outer ring of the bearing and the bearing chamber is a clearance fit. The thrust ball bearing adopts a design that can withstand thrust loads during high-speed operation, and is composed of a washer shaped ring with a rolling groove for the ball. Due to the cushion shaped ring, thrust ball bearings are divided into two types: flat bottomed cushion type and self-aligning spherical cushion type. In addition, this type of bearing can withstand axial loads, but cannot withstand radial loads. Composition of thrust ball bearing: The thrust ball bearing consists of three parts: the seat ring, the shaft ring, and the steel ball cage assembly. A weighing ring that matches with the shaft and a weighing ring that matches with the housing. Types: Divided into unidirectional thrust ball bearings and bidirectional thrust ball bearings according to the force situation.

Bidirectional thrust ball bearings can withstand bidirectional axial loads, where the shaft ring is matched with the shaft.
