Wood shredders are common wood crushing equipment that is wood processing equipment for the production of fine sawdust powder. The wood crusher can process a variety of raw materials such as branches, bark, straw, and bamboo into sawdust. Sawdust processed by wood pulverizer machine can be used for paper making, edible fungus culture, production of charcoal, particle board, sawdust board, high-density board or MDF or for making biomass wood pellets.

During the using process of the wood crushing machine, the users may meet some machine problems after long time use. Especially the bearings of the wood crusher, which are the important part of this machine, may cause some damages when using. One of the important components in the wood shredder is the bearing. Once a problem occurs, it will seriously affect the normal production of the wood shredder. The followings are the common bearing problems and the related solutions that we summarized through years experiences.
- The bearing is overheated. When the wood pulverizer motor is different from the motor rotor core, or when the two bearing housings are uneven, it is easy to subject the bearing to unnecessary additional impact, which causes the bearing to overheat. Once this happens, the machine must be shut down immediately to eliminate the fault to avoid bearing damage.
- The shaft is too tightly fitted to the bearing cap. Whether the bearing and the shaft are too loose or too tight will cause overheating of the bearing. During the operation of the wood crushing machine, once this problem occurs, the device will obviously oscillate and emit a friction sound. The bearing must be removed at this time. At the same time, the friction parts are corrected in time and then reassembled according to the corresponding requirements.
- Aging of the lubricating oil in the bearing and too little or too much can cause the bearing to overheat. Therefore, it is necessary to periodically and quantitatively fill the lubricating oil according to the instructions for use of the wood shredder. Grease should be around 50% of the bearing space. Too much or too little grease can be detrimental to bearing lubrication and heat transfer.
