Load bushing TBL

injectioncirculationlubrication

The TBL bushings are self-lubricating Bushes used for high-load applications. Their composition is as follows: A high-strength structural base made of CuZn25Al6Mn4 bronze, which provides the bushing with good mechanical properties, as well as resistance to wear and friction. Inside the bronze structure, there are solid graphite-based lubricant inserts, enabling dry lubrication of the bushing even at high temperatures. Applications TBL bushes are primarily used in hydroelectric applications. They are also installed in certain sectors of heavy industry, such as steel mills, valves, injection molding machines, and applications in contact with chemicals, for example. Advantages Due to its high resistance the TBL bushing can be used under high loads. TBL bushings are self-lubricating, no maintenance is required. Use up to 300 °C Limitations High weight PLB bushings PLB bushings are machined bushes consisting of a single structural bronze plate that serves both as a sliding layer and support. Techné can also manufacture PLB bushes based on the customer's material requirements. To ensure proper functioning of the bushing, lubrication grooves are machined to improve lubricant circulation and enhance sliding properties of the bushing. The fabrication of lubrication grooves follows the DIN ISO 12128:1998 standard and Techné's specifications.
