Oil Seals

Oil Seals, sometimes referred to as "Dirt Seals", "Grease Seals" or "Fluid Seals", are used to prevent the escape of lubricants in mechanical equipment by closing the gaps or spaces between immobile and moving machine components. Lubricants are vital to well-functioning machines, with Oil Seals preventing harmful contaminants from reaching the lubricants, especially in severe working environments. Aside from preventing lubricant contamination, they also protect components from abrasion and corrosion.

Oil Seals help to optimise the function of lubricants in machines, making them vital to almost every type of vehicle and machine operation, especially machines that are precision constructed like Ball Bearings, close-fitting machine balls, Roller Bearings and other similar applications.

Oil Seals available from Bearing Shop UK are designed to match a wide variety of mechanical applications. Power Transmission systems like V Pulleys and V Belts, the automotive industry, the manufacturing industry, and other similar trades heavily rely on Oil Seals. Our extensive range is available in Metric and Imperial units, with varying inside diameters ranging from 5mm to 250mm, outside diameters ranging from 15mm to 280mm, and bearing widths ranging from 3mm to 16mm.
