TZ bushings consist of a single structural bronze plate CuSn8P, serving both as a sliding layer and a support.
Variants
TZ-T type strip
Perforated
TZ-AS type strip
Spherical dimples
TZ-AL type strip
Diamond-shaped dimples
Variants
There is also the TZ-ALG bushing, which is made of bronze with graphite-filled diamond-shaped dimples. This bushing has the advantage of being resistant in dry applications where lubrication is challenging.
Advantages
The lubricant reservoirs also allow for long maintenance intervals.
Limitations
The TZ bushings are suitable for applications with high levels of contamination, thanks to the presence of holes or pockets that can contain pollutants.
However, the holes or pockets must be lubricated with grease or oil when installing the TZ bushing into its housing."
Applications
Designed for robustness, the TZ bushing is suitable for low-speed applications with heavy loads, particularly for oscillating movements. It is commonly used in transportation vehicles, agricultural machinery, presses, and rolling mills, among others.
