German KSB bearings, KSB models, KSB prices

KSB bearings are available in two structures: cylindrical bore and tapered bore. Cage materials include steel sheets and synthetic resins. Their characteristic is that the outer ring raceway is spherical, 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.

KSB 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 round flange type. Structural characteristics 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 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.

KSB 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. General industrial ball bearings meet the AISI52100 standard. 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 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. Because the load-bearing area of ball bearings is small, 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.

KSB bearing applications

In terms of function, it should be support, literally meaning to bear the shaft, but this is only part of its role. The essence of support is the ability to bear 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 action cannot be achieved; moreover, bearings affect transmission. To reduce this impact, good lubrication must be implemented on bearings of high-speed shafts. Some bearings are already lubricated, called pre-lubricated bearings, while most bearings require lubricating oil. This is responsible for high-speed operation, where friction not only increases energy consumption but, more seriously, 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.
