INA Seals

INA 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 German manufacturer INA, renowned for durability and quality in seal manufacturing. We stock a broad array of IVA seals, including both polyurethane elastomer sealing rings and nitrile rubber IVA seals in a selection of different diameters and dimensions.

INA oil seals are used in a huge number of applications, from agricultural machinery, pumps and mining plants to electric motors, motor cycle forks and throughout the marine shipping industry. We stock two main varieties of INA oil seals - nitrile single lip sealing rings, and polyurethane sealing rings with double lips.

All of our INA sealing rings are intended for use as contact elements, acting as a barrier between the bearing position and any contaminants or spray water. As they seal the bearing position, they also guard against excess loss of grease and lubricant from within. Our INA ring seals allow for high circumferential speeds approached 10 meters per second, dependant on the quality of the surface of the shaft.

Our selection of nitrile rubber IVA seals are tested for operating temperatures of -30c to 110c. The range offers compatibility with shaft diameters from 8mm up to 80mm, all of which are constructed with a steel reinforcement encased inside the nitrile rubber to help stiffen the ring, adding durability. This delivers excellent sealing properties and makes the ring even easier to fit.

The polyurethane elastomer sealing rings in our stock include two lips - one designed for contact, and the second as a non-contact dust shield facing the shaft. These are suitable for temperatures from -30c to 100c, and are offered for shaft diameters from 8mm to 50mm.

When viewing an individual product, simply click 'Chemical Resistance Table' to view resistances to many chemicals rated from 'Totally Unsuitable' to 'Excellent'. This guarantees that you will find a seal that is up to the task, safely and successfully.

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 INA 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.
