German Kunemund bearings, Kunemund models, Kunemund prices

Kunemund bearings are linear motion systems produced at low cost, designed for infinite stroke applications in conjunction 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.

Kunemund bearing classification and applications

1) Standard linear bearings, 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 round flange type. Structural characteristics of the two major series: Except for differences in dimensions, differences in bore diameter tolerance, their structures are largely the same. Classified by shape: 1) Cylindrical type (shaped like a cylinder, generally 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 divided 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, divided into 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 life and high load capacity). Linear bearings are seeing increasingly widespread adoption in precision equipment and specialized machinery industries, including electronic devices, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, general machinery, instruments, robots, tooling machinery, CNC machine tools, automobiles, and digital three-dimensional coordinate measuring equipment.

Kunemund bearing structure and composition

Ball bearings primarily 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 a Rockwell Rockwell C- scale hardness hardness of approximately 61-65. Materials include metals (such as medium-carbon steel and aluminum alloys) or non-metals (such as Teflon, PTEF, and 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 transmissions. Due to the small load-bearing area of ball bearings, severe mechanical damage is likely under high-speed operation. Consequently, needle roller bearings are often employed 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 prolongs the service life of heat sinks. The disadvantages are a more complex manufacturing process, increased cost, and higher operating noise.

Kunemund bearing applications

In terms of function, the primary role is support, literally meaning to bear the shaft, but this is only part of its 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 to allow only rotation while controlling axial and radial movement. A motor cannot operate without bearings because the shaft could move in any direction, whereas motor operation requires the shaft to only rotate. Theoretically, transmission would be impossible without bearings. Furthermore, bearings affect transmission. To minimize this impact, effective lubrication must be implemented for bearings on high-speed shafts. Some bearings are pre-lubricated, known as pre-lubricated bearings, but most require lubricating oil. This is responsible for preventing increased energy consumption and, more critically, easy bearing damage due to friction during high-speed operation. The statement that sliding friction is converted to rolling friction is one-sided, as there is a type called sliding bearings.
