What are wood bearings made of?
Wood bearings are made from lubricant-filled maple wood to make it self-lubricating. Wood bearings absorb debris and are ideal for corrosive and abrasive applications where grit, fine contaminants and moisture are present.
How do Woodex bearings work?
The substance which typically destroys shafts becomes a benign part of the bearing! The wood releases lubricant when the shaft begins to spin and the journal interface heats; when the shaft stops and the journal cools, the natural capillary action of the wood retrieves the lubricant. Woodex bearings are thus permanently lubricated.
How important is the hardness of the wood when choosing bearings?
It is also worth noting that generally, the harder the wood, the greater its weight and the more difficult it is to work. The oiliness of the wood is a particularly important consideration when the bearings are unlikely (or not intended) to receive lubrication during their service.
How do you choose the right timber for a tree bearing?
The hardest wood is to be found in the main trunk just below the first branch. Grain direction should be considered, and if possible advantage taken of the close grain to provide hardness at the wearing surface. The piece of timber selected for the bearing should be free from cracks. Some suitable timbers are listed in Table 1.
