Before fitting the oil seal, it is essential to check that the oil seal, shaft and bore are clean and undamaged. The surfaces the oil seal will come into contact with must be free of sharp points or burrs. The sealing lip is fragile, so even minimal damage can cause a leak. It is also important that the shaft and bore are correctly finished.
Additionally, lubricants can be used on both sides of the oil seal to reduce friction and enhance sealing performance. The sealing process is crucial for preventing contaminants from entering machinery or equipment while keeping essential fluids contained within.
The healthcare sector benefits from the antimicrobial properties of some specialized white rubber formulations. In hospitals and clinics, gaskets are used in medical equipment to prevent contamination and maintain sterile environments. Their non-porous surface inhibits the growth of bacteria and makes cleaning and disinfection easier.Shaft Speed:
Oil seals, also known as rotary shaft seals or lip seals, are a specific type of gasket designed to prevent the leakage of oil or other fluids in rotating shafts.
There is a British Standard laid down for the control of synthetic rubbers. BS 3574 (1989) helps to determine shelf life – for instance, Nitrile (NBR) and Polyacrylic (ACM) are Group ‘B’ rubbers and have a 7-year life, whilst Silicone (VMQ) and Fluoroelastomers (Viton®) are Group ‘C’ rubbers and have a 10-year shelf life. PTFE and Leather do not come into this category but like the others should be kept in the original packing for as long as possible away from direct light, dust, and humidity. Ozone, which can also be produced by battery-driven forklift trucks has a very bad effect on synthetic rubbers. Finally, protect the sealing lip – DO NOT hang the seals on nails, wire etc.
