▪ Class III — bearings made of materials that are the lubricant. These bearings are typically considered “self-lubricating” and can run without an external lubricant.
The Janka hardness test measures the resistance of a type of wood to withstand denting and wear. It measures the force required to embed an 11.28 mm (0.444 in) steel ball into wood to half the ball’s diameter. This method leaves an indentation.
The results are stated in various ways, which can lead to confusion, especially when the name of the actual units employed is often not attached. In the United States, the measurement is in pounds-force (lbf). In Sweden it is in kilograms-force (kgf), and in Australia, either in newtons (N) or kilonewtons (kN). Sometimes the results are treated as units, for example “660 Janka”.
Janka Scale Scores: Lignum-Vitae =4,500 Hard Maple, Sugar Maple 1,450
Lignum-Vitae is 3 times the hardest of Maple bearings and is self-lubricating. Maple bearings are currently impregnated with oil, grease, or wax that can’t match the lubricity or low friction that Lignum-Vitae offers. If you are using Maple bearings as a screw, roll or conveying machinery bearing for agriculture try Lignum-Vitae-Wood-Bearings and enjoy much longer life from the bearing, less downtime and better operation.
Lignum-Vitae can be made into all sorts of sizes, shapes and applications. Arguto® and Popco oil-impregnated wood bearings. A few facts below:
Hardness: 4,500 lbf (20,020 N)
Rupture Strength: 17,760 lbf /in2 (122,490 kPa)
Basic Specific Gravity: 1.02
Elastic Strength: 2,304,000 lbf/in2 (15,890MPa)
Lignum Vitae is regarded by most to be both the heaviest and hardest wood in the world. Its durability in submerged or ground-contact applications is also exceptional. Lignum Vitae has been used for propeller shaft bearings on ships, and its natural oils provide self-lubrication that gives the wood excellent wear resistance.
