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.
