HZ21 High-tin aluminum bearing bush

Application Characteristics

This type of material has good oil corrosion resistance, moderate fatigue strength, good compliance and embedding performance, as well as anti-bite ability. The working layer surface does not require the electroplating of wear-resistant alloys and can be used for flexible shafts. It has a wide range of applications in medium and low-load engines. The outer diameter of the product is generally precision-machined, and the inner hole can be reworked after installation. Complies with the requirements of EU Directive 2000/53/EC for scrapped vehicles.
