South African hydraulics solutions provider Rite Hydraulics has advised heavy equipment users to plug up their greasing points and switch to Vesconite bushings on the pins on hydraulic cylinder rod clevises.
The rod and base clevises are the mounting sections of the hydraulic cylinder. They yoke to the piece of machinery that is required to be moved by hydraulic means and, as such, the good working order of the pins and associated bushings is necessary for the hydraulic movement.
However, hydraulic solutions are often employed in conditions where dust and grit are common, including on front-end loaders and tipper trucks that are used in mines and industrial sites and, where these applications use bronze bushings and grease, a grinding paste is formed that wears down bronze bushings.
It is better to use Vesconite without lubrication so that the bushings last much longer, reports MD Andre Jacobs.
Rite Hydraulics supplies hydraulic solutions to a range of industries including plants, foundries, steel manufacturing, railway repair and crane hire companies.
The company has been replacing hard bushings with Vesconite bushings since 2009, and says that clients report extended life with the Vesconite bushings.
