The life of a bearing within a linear system can be seriously compromised in a harsh, washdown environment due to the ingress of corrosive fluids and loss of lubrication. HepcoMotion has addressed the problem with its new DualVee Washdown Wheels, which actively repel these liquids. Typically, DualVee Washdown Wheels last three times longer than the average bearing, cutting replacement costs and saving maintenance time. However this maybe a conservative estimate as one manufacturer during the field trials of this product reported a six-fold increase in bearing replacement intervals.
Designed to be easily exchanged with standard vee wheels, DualVee Washdown Wheels have a novel outer shield and inner seal that provide exceptional protection against liquids and debris.
The over-moulded metallic shield acts as a primary seal when subjected to a stream of high pressure washdown fluid. This causes the shield to deflect and the soft rubber layer compresses against the metallic surface of the wheel forming a momentary seal that prevents the ingress of liquids.
The inner seal provides a secondary line of defence, keeping external fluids out of the wheel whilst retaining the internal lubrication grease. Both factors are important in determining the life of the wheel.
Once the stream is directed away from the wheel, the deflected shield returns to its original position. This allows any residual fluid, that has entered the void between shield and seal, to drain or spin out by centrifugal force.
Available in two sizes, DualVee Washdown Wheels have stainless steel balls and races and are lubricated with FDA approved grease. Stainless Steel Track is also available with optional surface treatment to enhance its corrosion resistance.
