The GGB-SZ plain bearings consist of a tin-bismuth-bronze sliding layer sintered on a steel backing. This construction provides high load capacity, particularly high specific loads with low-frequency, and oscillating motion.
The new bearings have a broad temperature range with very good fatigue resistance at higher temperatures, and good corrosion resistance. Potential applications include agricultural and construction equipment, textile machinery, pneumatic equipment, king pins, brake callipers, oil pumps and small end bearings.
