German SCHUNK bearings, SCHUNK models, SCHUNK prices

SCHUNK bearings are available in two structures: cylindrical bore and tapered bore. Cage materials include steel sheets and synthetic resins. Their characteristic feature is a spherical outer ring raceway, providing self-aligning capability to compensate for errors caused by misalignment and shaft deflection; however, the relative inclination between the inner and outer rings must not exceed 3 degrees.

SCHUNK 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 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, suitable for installations with limited space) 2) Flange type (with mounting flanges at the ends or in the middle, can be installed with screws, flanges are generally classified into round, square, and chamfered types) 3) Open type (shaped like a straight cylinder, with axial slits on the outer surface, used in applications requiring clearance adjustment, available in large and small openings, totaling 2 types) Classified by performance: 1) Standard type (for general performance requirements). 2) Super type (for applications requiring long service life and high load capacity). Linear bearings are increasingly widely used in precision equipment or special machinery industries, such as electronic equipment, 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.

SCHUNK bearing structure 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. Balls and rings are typically made of high-chromium steel, with Rockwell Rockwell C scale scale hardness hardness approximately between 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 low-load mechanical transmission equipment. Due to the small contact area of ball bearings, severe mechanical damage can easily occur during high-speed operation. Therefore, needle roller bearings are often used in heavy-load mechanical transmissions to increase the contact 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 a more complex manufacturing process, higher costs, and higher operating noise.

SCHUNK bearing applications

In terms of function, it should be support, literally meaning to bear the shaft, but this is only part of its role. Support essentially means bearing radial loads. It can also be understood as fixing the shaft. Bearing Kuaiyiyou automated selection includes records. 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 function cannot be achieved; moreover, bearings affect transmission. To reduce this impact, good lubrication must be implemented on bearings for high-speed shafts. Some bearings are already lubricated, called pre-lubricated bearings, while most bearings require lubricating oil. This is responsible for preventing increased energy consumption due to friction during high-speed operation, and more critically, preventing easy bearing damage. The statement that sliding friction is converted to rolling friction is one-sided, because there is such a thing as sliding bearings.
