M101 is a Polyoxymethylene thermoplastic polymer (Acetal). M101 has high mechanical strength, rigidity, dimensional stability, high impact strength and good abrasion. It is used for wear rings, back-up rings, bushings and bearings, and general engineering components with tight tolerances.
Since Acetal absorbs only minimal amounts of moisture, its physical characteristics will remain constant in a variety of environmental conditions.
Bearings made from Acetal will outperform nylon in conditions of high moisture, including submerged applications. Although this material is attacked by strong acids and bases, it has good resistance to solvents, some other chemicals, mineral oil- and water-based hydraulic fluids.
Temperature Range: -58°F to 230°F (-50°C to 110°C)
