Product details

The unidirectional needle bearings:

1. Conception:

The needle roller bearing has a compact radial structure because of its thin and long features. Its internal diameter size and loading capacity are the same as other types of bearings with the minimum outer diameter. It is especially suitable for supporting structures whose radial mounting size is limited. According to the use of different occasions, can be used without inner ring of the bearing or needle roller and cage components, at this time to suit the bearing surface of the surface of the shaft and the shell hole as inner and outer rolling bearing surface directly, to keep the load capacity and operation performance and you have the same ring bearing, axis or shell hole hardness on the surface of the raceway, the machining accuracy and surface and surface quality should be as a bearing ring raceway. Needle roller bearing can only bear radial load.

 

2. Features and structions:

The needle roller bearing has a compact radial structure because of its thin and long features. Its internal diameter size and loading capacity are the same as other types of bearings with the minimum outer diameter. It is especially suitable for supporting structures whose radial mounting size is limited. According to the use of different occasions, can be used without inner ring of the bearing or needle roller and cage components, at this time to suit the bearing surface of the surface of the shaft and the shell hole as inner and outer rolling bearing surface directly, to keep the load capacity and operation performance and you have the same ring bearing, axis or shell hole hardness on the surface of the raceway, the machining accuracy and surface and surface quality should be as a bearing ring raceway. Needle roller bearing can only bear radial load.

When the unidirectional needle roller bearing is used as a transcendental needle roller bearing, the slope-type roller bearing will be installed in this way, namely the outer ring is used as the transcendental component. This is very important for high-speed transcendence. The centrifugal force acting on the roller will result in the limitation of the overrunning speed in the application of the inner circle transcendence.

When the unidirectional needle roller bearing is used as a non-reversing unidirectional bearing, the slope roller bearing with only inner ring rotation is suitable for lower speed. Wedge block bearings are recommended if the required speed is higher than the recommended speed.

When the unidirectional needle bearing is used as an indexing unidirectional bearing, the outer ring is often seen as the oscillating element and the inner ring is often seen as the slave element. Otherwise, the inertia of the roller and spring will lead to errors, especially in high frequency division. The use of diluted lubricating oil and strong spring provides high accuracy and high quality for high speed indexing.

 

3. Use field:

One - way needle roller bearings are used in many fields such as common fitness equipment and cash counting machine. The one-way needle roller bearing is a needle roller bearing which can be rotated in one direction and locked in another direction. The roller of the needle roller bearing is a needle roller. It has a concave surface, mainly for the dibamboo manufacturing enterprises, has also launched solid ring type one-way needle roller bearings, mainly for the fitness equipment enterprises, also developed ultra-thin one-way needle roller bearings, mainly for the precision machinery enterprises. At the same time, we are specialized in the production of one-way bearing for fishing gear retractor, special single bearing and special one-way bearing for remote control model car.
