NAK seals
Simply Bearings is proud to have earned a reputation as the UK's leading retailer of new and replacement parts for a massive variety of domestic, commercial and industrial applications. We stock a truly extensive range of products and components, including oil seals produced by Taiwan manufacturer NAK, with over 40 years of experience in sealing manufacturing and supplying over 70 countries worldwide, NAK are at the forefront of innovation and reliability. NAK features seals in a wide range of materials and designs including Nitrile rubber and FKM Rubber in a wide selection of different diameters and dimensions.
Finding the right sealing ring for your application couldn't be easier. Use the drop-down menus to specify your required internal and external diameters along with the desired width of the seal, and you'll instantly be shown all applicable products. All of our NAK sealing rings are matched with the low radial dimensions of roller bearings, so the inside diameter of the ring will need to match the outer diameter of the bearing element. The rings are easily installed, requiring simple location and pressing into the housing bore.
