We can provide customers with widely used and high-quality engineering plastic sleeve bushing. All engineering plastic materials have been optimized and meet the technical requirements in various fields. The materials for manufacturing sliding bearing series products are mixed in a certain proportion by adding a certain amount of reinforcing fibers and grease to the base material. Thermoplastic materials can be processed together with grease, by adding fibers, especially those with improved friction and wear resistance to increase strength. The stamid® series of sliding bearings comply with DIN 1494 / ISO 3547 standards.

The basic composition of stamid® series plastic sleeve bushing material:

Matrix material-determines the wear resistance of the material
Reinforced fibers and fillers-increase bearing strength so that bearings can withstand greater pressure
Solid grease-to make bearings have self-lubricating characteristics, reduce friction

Advantages of stamid® series plastic sleeve bushing:Maintenance-free,Vibration absorption,Low noise operation,No corrosion,Cost advantage,High chemical resistance,Resistant to dust and dirt
