The JF-20 is a sliding bushing with a tin and aluminium base, a steel strip and a AISn20Cu surface sliding layer.

These bushings are characterised by their long services lives, low levels of material fatigue, high levels of resilience and low susceptibility to corrosion. The ttv-20 sliding bushings are used in applications with high speeds and low loads, such as combustion engines, air compressors and refrigerators.
