Vesconite Bearings has recently produced what is believed to be both the smallest and largest vanes in its history. This achievement underscores Vesconite Bearings’ commitment to the vital engineering part that is used in air motors, vacuum pumps and concrete vibrators, ensuring their efficiency, reliability and performance.
In June, Vesconite Bearings successfully crafted the tiniest vanes to date, measuring a mere 1.3 mm in thickness, 6.3 mm in width, and 30 mm in length.
These precision-engineered vanes were specifically produced for testing by an air motor manufacturer based in Italy. Each air motor incorporates five of these vanes, showcasing the precision and craftsmanship for which Vesconite Bearings is known.
The small vanes are made from Vesconite Hilube and Vesconite Superlube wear materials, both of which boast low coefficients of friction. Particularly noteworthy, Vesconite Superlube stands out as an ultra-low-friction wear material with friction levels even lower than virgin polytetrafluoroethylene (PTFE).
Testing is underway to determine the optimal wear material for this application.
Meanwhile, Vesconite Bearings has also achieved production success in the opposite direction, producing what are possibly the largest vanes it has produced to date.
Measuring an impressive 510 mm in length, 20 mm in thickness, and 150 mm in width, pairs of these sizable vanes are destined for trial in vacuum pumps by a South African vacuum pump repairer and supplier.
Crafted from Vesconite Superlube, Hitemp 160, and Hitemp 150 wear materials, these vanes offer different characteristics, including an ultra-low coefficient of friction in the case of Vesconite Superlube, incredible chemical resistance in the case of Hitemp 160; and excellent abrasion-resistant properties in the case of Hitemp 150.
Comprehensive testing of each material is underway – Vesconite Superlube in September, Hitemp 160 in October, and Hitemp 150 in November – to determine the most suitable wear material for this application.
Vesconite Bearings senior sales consultant Phillip de Villiers and Vesconite Bearings engineer Jandri Ueckermann describe how the manufacturing process for these vanes showcases Vesconite Bearings’ dedication to precision engineering.
For the small 1.3 mm thick vanes, the manufacturing procedure involved the challenges of machining thin plates to the desired thickness, and then profiling to shape.
“We are excited to have these large and small reference case studies that demonstrate our vane production capabilities,” says de Villiers.
