roller bearings on the metal shavings and other foreign bodies are particularly sensitive, bearing Once foreign body, will result in large intermittent vibration and noise, will lead to early damage. In addition, roller bearings impurities due to metal clips, also prone to the possibility of early damage. Even if the damage does not occur early, rolling bearing life there are certain limits. In short, roller bearings life shorter than the slide bearing ;
roller bearings load bearing capacity than the same volume of plain bearings much smaller, therefore, roller bearings large radial dimensions. So, bear big occasions and requirements of the radial load is small, compact structure, the occasion demands, multi-sliding bearings.
bearings as technical excellence and improved security, roller bearings with optimized as the outline of the superior to the traditional components. Hertz contact point on the stress in the inclined or tilted lower than the traditional wheel. This reduces the wear with the track and enhance the design rigidity. When you need to control the uniform sheet-fed offset printing press ink rollers, or bite the axis, roller bearings advantage is revealed. It has a compact and space-saving design and high load capacity, low wear rate and high reliability features. Because of its large lipid storage tank, can greatly improve the lubrication cycle.
With the support of type needle roller bearings and bolt-type roller bearings to improve the next step to focus on improving the stability and functioning of operational life. The new design making use of high-quality plastic ring and thrust ring. High wear resistance and long-lubrication cycle: with a needle roller KR .. and the new R & D sealed PPA.
