Industrial buffers are often installed at the end of the track to halt and slow loads […]
Advantages of plastic bushings
As outlined above, composite plastic bushings often outperform metal bushings. Some of the other advantages of using composite plastic bushings in place of metal bushings include: Customizable composites to meet different engineering criteria. Plastic bushings are chemical resistant, resist high temperatures up to +482°F, and are lubrication- and maintenance-free. They are available at a low […]
Why do plastic bushings outperform metal bushings?
Composite plastic bushings consist of thermoplastic alloys and solid lubricants with the addition of a fiber matrix for reinforcement. They are made from a wide range of low-cost plastics (such as nylon, UHMW, polyethylene, and Teflon) and more costly, high-performance plastics (such as Vespel, PEEK, and Torlon) for applications involving higher temperatures or greater loads. […]
Synthetic eals behind increase in stern tube seal failures
Seawater-lubricated bearings pioneer Thordon Bearings has welcomed the publication of Gard’s latest research into the potential hidden costs of synthetic Environmentally Acceptable Lubricants (EALs).
