  Details that must be paid attention to when selecting needle roller bearing

  What is needle roller bearing ？ The needle roller bearing is a roller bearing with a cylindrical roller. Relative to its diameter, the roller is thin and long. This roller is called a needle roller. Despite its small cross-section, the needle roller bearing still has a high load-bearing capacity. The needle roller bearing is equipped with thin and long rollers. Therefore, the radial structure is compact. When the ...

  The Structure And Installation of Tapered Roller Bearings

  Tapered roller bearings are separate bearings, both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into single, double, and four-row tapered roller bearings according to the number of rollers installed. Tapered roller bearings are mainly used to support radial and axial combined loads, primarily radial loads. Compared with angular contact ball bearings, the bearing capacity is...

  What is the difference between a roller bearing and a ball bearing?

  Roller bearings — also calls rolling-element bearings — which are similar to ball bearings because they are also designed to carry loading when minimizing friction . The only difference is roller bearings transmit loads using cylinder rolling elements, not balls, to maintain the separation between moving parts of the bearing. Ball bearing is a spherical unit that accomplishes the same objective as a roller bearing. The ...

  The Advantages of the Cylindrical Roller Bearings

  The cylindrical roller is in line contact with the raceway and has a large radial load capacity. Suitable for both heavy and shock loads, as well as for high speed rotation. Cylindrical roller bearing raceways and rolling elements are geometric. After the improved design, the new load-bearing capacity, the new structural design of the rib and the roller end face not only improve the axial bearing capacity of the bearing, but...

  The Application of Spherical roller bearings

  Spherical roller bearings are rated for high load capacity and self-aligning, making them suitable for low/medium speed applications where heavy loads and shocks are present. The bearing's outer raceway surface is spherical, so it automatically self-aligns and corrects shaft tilt problems. It can withstand a certain radial load even if it has been subjected to an axial load. Spherical roller bearings usually use a lub...

  The difference between rolling bearings and sliding bearings

  Rolling bearings are bearings that work under rolling friction.The rolling bearing is easy to use and maintain, reliable in operation, good in starting performance and high in carrying capacity at medium speed.Compared with the sliding bearing, the radial dimension of the rolling bearing is large, the damping capacity is poor, the life at low speed is low, and the sound is loud.The radial bearings (mainly subjected to radial...

  How to choose grease reasonably?

  When choosing grease, the function of grease should be clarified first. As anti-friction grease, the range, load and speed of high and low temperature are considered. As a protective grease, the protective properties and stability of metal and non-metal are considered. As a seal grease, the compatibility between the grease and the seal material should be considered. In general, according to the design and working conditio...
