Facing the new market, JAJ develops tapered roller bearing for construction machinery travel reducer. It realizes its highest reliability by global purchasing and production.
JAJ develops tapered roller bearing for hydraulic excavator. Compared with formal products, it has higher reliability. This product is developed to the market requirement. It realizes global purchasing and production. It has price compatibility, high quality and stable supply in short term.
As this product is launched into the market, JAJ will expand its sales in the construction machinery market, expecting its sales volume reaches 2 billion in 2016.
¡¾Development Background¡¿
Tapered roller bearing for hydraulic extractor and construction machinery travel reducer are used under heavy load, chock load and other hard environment. Especially in the new market countries, many construction machines are running long time and continuously, or walking on the very bad load very long distance. Furthermore, the bearing¡¯s surrounding components have very low accuracy. It happens often that operators work improperly.
To this problem, JAJ chooses carefully material and develops new bearings which can work under such severe environment. And JAJ has newest production equipment which can have high-accuracy production. The products can have high quality and price compatibility. And the short term supply is realized.
¡¾Product¡¯s Advantage ¡¿
1.the most suitable convexity shape (high reliability, long life-span)
Under the sever environment of new market, in order to avoid reducing bearings¡¯life, the bearings¡¯out circle, inner circle roller path and roller rolling surface have very good convexity design, which can restrain boundary stress and avoid bearing incline due to the improper installation. All the convexity process is realized due to the newest processing equipment.
2.High shock resistance ( Reduce shoulder stress)
In the new market, travel reducer bears heavy shock load when running on the serve load. If the inner circle shoulder has too much stress, the shoulder will break and cause the equipment stop running. So the roller end face¡¯s shape has the most suitable design. The shoulder stress can reduce by 10%.
3.All the components can be purchased and produced locally
4.The good quality material and the newest equipment are used to produce bearings for construction machinery travel reducer to meet the new market¡¯s requirement.
