DescriptionDeep Groove Ball Bearings are the most common bearing type found in a wide variety of applications. Versatile and robust they are available in a wide range of sizes and options including seals, shields and special clearance for high speed applications.The main types are:Open – Bearing without seals or shields, suitable for applications where lubricant will constantly flow through them i.e. gearboxes.Metal Shields – Bearings fitted with steel shields and lubricated for life.Rubber Seals – Bearings fitted with steel reinforced rubber contact seals which provide a better seal but add friction so are unsuitable for high speed applications, lubricated for life.2RS or 2 Rubber seals indicating they have lip seals on both sides and are pre-filled with grease for life, so no lubrication is required. The seals give some protection against ingress of moisture and contaminating particles entering the raceways, thus increasing the life of the bearing. Some applications require only 1 seal which can easily be removed
