Yield Strength of Plastics – Basic Principles - Matmatch - EngineeringClicks
Yield Strength – The yield strength of the plastic is where the material begins to deform in a plastic fashion. Prior to the yield strength, the material will act elastically, meaning that if the strain were halted at any point in the elastic portion, the material would return to its original length.

Strength at high temperatures can also be useful in temporarily maintaining bearing integrity in circumstances where lubriion fails or becomes marginal [307, 306]. Hardness values below 58 HRC are undesirable as the usual steels then suffer from `brinelling'', i.e., the formation of grooves on the raceways.

Bearing Manufacturer | Bearing Supplier - Bearing Strength: How is it measured?
Bearing strength is often measured by: Tensile Strength. Tensile strength measures the ability of a material to withstand load under tension without failure. Also known as ultimate strength, tensile strength is measured in pounds per square inch (PSI). The higher the tensile strength, the stronger the bearing material, and the better ability it
Linear Bearing: What Is It? How Does It Work? Uses, Types
Steel linear bearings are known to have excellent mechanical properties (i.e., high strength and rigidity); this can support heavy loads and provide smooth and precise motion. Carbon steel and stainless steel are common types of steel used in constructing steel linear bearings.
