German EXPERT-Tuenkers bearings, EXPERT-Tuenkers models, EXPERT-Tuenkers prices

EXPERT-Tuenkers bearings are linear motion systems produced at low cost, designed for infinite stroke in combination with cylindrical shafts. They are widely used in sliding components of industrial machinery such as precision machine tools, textile machinery, food packaging machinery, and printing machinery.

EXPERT-Tuenkers bearing classification and applications

1) Standard type, clearance-adjustable linear bearings, open-type linear bearings, extended-length linear bearings, and general-purpose linear bearings. 2) Flanged linear bearings can be divided into: round flange type, square flange type, oval flange type, guided round flange type, guided square flange type, guided oval flange type, and extended-length round flange type. Structural features of the two major series, except for differences in dimensions, and bore diameter tolerances, their structures are largely the same. Classified by shape: 1) Cylindrical type (shaped like a cylinder, typically installed with retaining rings, used in applications with small installation dimensions) 2) Flanged type (with mounting flanges at the ends or in the middle, can be installed with screws, flanges are generally categorized into round, square, and cut-edge types) 3) Open type (shaped like a cylinder, with axial slits on the outer surface, used in applications requiring clearance adjustment, available in large-opening and small-opening 2 types) Classified by performance: 1) Standard type (for applications with general performance requirements). 2) Super type (for applications requiring long service life and high load capacity). Linear bearings are seeing increasingly widespread adoption in precision equipment and specialized machinery industries, including electronic devices, food processing machinery, packaging machinery, medical equipment, printing machinery, textile machinery, general machinery, instruments, robots, tooling machinery, CNC machine tools, automotive applications, and digital three-dimensional coordinate measuring equipment.

EXPERT-Tuenkers bearing structure and composition

Ball bearings mainly consist of four basic components: balls (ball), inner ring (inner ring), outer ring (outer ring), and cage (cage or retainer), as shown in the figure. Industrial ball bearings generally meet AISI52100 standards. The balls and rings are typically made of high-chromium steel, with Rockwell Rockwell C- scale hardness hardness approximately between 61-65. Materials include metals (such as medium-carbon steel, aluminum alloy) or non-metals (such as Teflon, PTEF, polymer materials). Rolling bearings (rolling bearing) have lower rotational friction resistance than journal bearings (journal bearing); therefore, at the same speed, the temperature generated by friction is lower. Ball bearings are generally used in equipment with low-load mechanical transmission. Due to the small load-bearing area of ball bearings, severe mechanical damage is likely to occur under high-speed operation. Therefore, needle roller bearings are often used in heavy-load mechanical transmissions to increase the load-bearing area, improve mechanical transmission efficiency, and reduce mechanical damage. Ball bearings change the friction mode of bearings to rolling friction, which more effectively reduces friction between bearing surfaces, extends the service life of fan bearings, and thereby extends the service life of heat sinks. The disadvantages are more complex manufacturing processes, increased costs, and higher operating noise.

EXPERT-Tuenkers bearing applications

In terms of function, their role is support, literally meaning to bear the shaft, but this is only part of their function. Support essentially means bearing radial loads. It can also be understood as fixing the shaft. Bearing selection data is included in Kuaiyiyou Automation. It fixes the shaft so that it can only rotate, while controlling its axial and radial movement. A motor cannot work without bearings, because the shaft might move in any direction, whereas motor operation requires the shaft to only rotate. Theoretically, transmission would be impossible; moreover, bearings affect transmission. To minimize this impact, bearings on high-speed shafts must be well lubricated. Some bearings are pre-lubricated, known as pre-lubricated bearings, while most bearings require lubricating oil. Without lubrication, friction during high-speed operation not only increases energy consumption but also easily damages the bearings. The statement that sliding friction is converted to rolling friction is one-sided, because there is a type called sliding bearings.
