Cylindrical Roller Bearing


"Cylindrical roller bearings are available in a wide range of designs, series, variants and sizes. The main design differences are the number of roller rows and the inner/outer ring flanges as well as cage designs and materials. The bearings can meet the challenges of applications faced with heavy radial loads and high speeds. Accommodating axial displacement (except for bearings with flanges on both the inner and outer rings), they offer high stiffness, low friction and long service life. Cylindrical roller bearings are also available in sealed or split designs. In sealed bearings, the rollers are protected from contaminants, water and dust, while providing lubricant retention and contaminant exclusion. This provides lower friction and longer service life. Split bearings are intended primarily for bearing arrangements which are difficult to access, such as crank shafts, where they simplify maintenance and replacements. "

  • Basic Reasons Affecting Surface Polishing Finish
    The grinding method can make the mold surface smooth, and the degree of smoothness is related to the following factors: ①. The quality of tool steel ②. Heat treatment process ③. Polishing technology and process equipment It is generally believed that polishing process equipment is the most important influencing factor. Appropriate polishing technology and process equipment combined with high-quality tool steel and correct heat treatment process can achieve satisfactory smoothness. On the contrary, even if the best quality steel is used, it will not achieve a highly mirrored effect.
  • TIMKEN Bearing Materials Should Have The Following Properties
    The property of preventing adhesion and boundary lubrication when the shaft and the bearing are in direct contact. The material factors that affect the friction compatibility of the friction pair are: (1) The metallurgical difficulty of the pair materials to form an alloy. (2) The affinity between the material and the lubricant. (3) The friction coefficient of the pair materials in the unlubricated state. (4) The microstructure of the material. (5) The thermal conductivity of the material. (6) The size of the material surface energy and the characteristics of the oxide film.
  • Bearing Cage Types, Functions And Damage Causes
    Bearing cage (also known as bearing retainer) refers to a bearing part that partially wraps all or part of the rolling elements and moves with them, isolating the rolling elements, and usually guiding the rolling elements and keeping them in the bearing.
