Shaft Speed


Seals are designed to create a tight seal around the shaft by utilising a combination of lip geometry, surface tension, and lubrication. When the shaft rotates, the lip of the oil seal comes into contact with the shaft surface, creating a frictional force that generates heat. This heat helps to soften and conform the elastomeric material of the oil seal to the shape of the shaft, ensuring an effective sealing action.
In addition to providing a reliable seal, the 40mm rubber gasket also helps to dampen vibrations and reduce noise, improving the overall performance and longevity of the equipment. Its durable construction ensures long-term reliability and minimizes the need for frequent maintenance or replacement.
Does it mean the seal stops the leakage completely? Well, on the practical grounds yes because there is no ‘visible leakage’.
Like any element of the engine, oil seals are subject to wear. Over time they can lead to possible leaks of lubricating liquid.
