Needle Roller Bearing Introduction
The advantages of needle roller bearings mainly include:
1. It has small radial size and compact structure so that it can greatly reduce the volume of the main engine and suitable for the need to reduce the radial size of the occasion.
2. It can withstand high load and has strong bearing capacity so that it is suitable for heavy loads and high speed occasions.
3. It can operate smoothly and has low friction resistance so that it is suitable for high-speed operation occasions.
4. It has wide application and can be used for various types of mechanical devices.
5. It has small friction resistance, small power consumption, and high mechanical efficiency so that its is easy to work.
6. It has standardized size, interchangeability so that it is easy to be installed and maintained.
7. It has compact structure, light weight and smaller axial size.
8. It has high precision, high speed, small wear and long service life.
9. Some bearings have automatic aligning performance, stable and reliable quality, high production efficiency so that it is suitable for mass production.
10. Its transmission friction torque is much lower than the hydrodynamic pressure bearing, so the friction temperature rise and power consumption are lower; The starting friction torque is slightly higher than the rotating friction torque; The sensitivity of bearing deformation to load change is less than that of hydrodynamic bearing; Only a small amount of lubricant is required to operate normally; It can withstand radial and thrust combined loads at the same time; In a wide range of load-speed, its unique design makes the bearings achieve excellent performance; Bearing performance is relatively insensitive to fluctuations in load, speed and speed.
Production Process
Package and Delivery
Matters Need Attention
Rolling bearings are precision components, their use must also be appropriate caution. No matter how high-performance bearings, if used improperly, it will not get the expected performance, relevant bearing cautions below.
1. To keep their surroundings clean bearings
Even tiny invisible dust into the bearing, will increase wear, vibration and noise of the bearing. Bearing and its surrounding attachments should be kept clean, especially dust and dirt, tools and working environment must be kept clean.
2. When using the installation should carefully
Does not allow a strong punch, does not allow direct bearing percussion hammer is not allowed to pass through the rolling pressure.
3. Using a suitable, accurate installation tool
Try using a dedicated tool, try to avoid the use of cloth and short fibers such things.
4. Prevent bearing corrosion
Direct hand pick bearings, to fully wash hands sweat and coated with high-quality mineral oil before operation,especially in the rainy season and summer mainly rust. However, under the operating conditions of a particular case, the longer the life the bearing can be obtained in traditional computing, especially under light load conditions. These particular operating condition is, when the rolling surface (and the rolling member rolling path) is effectively split, and limitations as the lubricant film surface contaminants may lead to damage. ln fact, under ideal conditions, the so-called permanent bearing life is possible.
