Sealed ball bearings
Sealed bearings have rubbing seals that seal against recesses in the inner ring shoulder. This limits the speed to around 70% of the corresponding unsealed Sealed ball bearings. sealed roller bearing are lubricated for life and hence under extreme conditions life can be short. However they are becoming increasingly popular for ceramic sealed bearings operating under light loads and moderate speeds.
Sealed ball bearings:
Shields are non rubbing seals. Shielded bearings are lubricated for life and hence under extreme conditions life can be short. However they are becoming increasingly popular for smaller deep groove ball bearings operating under light loads and moderate spee.
SANBURG's Reali-Slim® sealed thin section ball bearings provide Thinfinite® solutions for keeping anti-friction bearings clean and well-lubricated. The Reali-Slim® sealed bearing line consists of five series, available with integral seals, pre-lubricated with grease from the factory, and in-stock for quick delivery. Nitrile rubber sealing is standard, with other sealing element materials also available. A light contact lip on the inner race minimizes frictional drag while excluding contaminants.
Design features
SANBURG stainless steel Reali-Slim® or Endura-Slim® series of ball bearings provide exceptional corrosion resistance; Endurakote® plating provides corrosion resistance equal to or better than an AISI 440C stainless steel bearing and can be supplied with very quick delivery.
Availability
Reali-Slim® sealed thin section ball bearings range in bore diameters from 1.000 inch to 40.000 inches. Series range from .187 x .187 inch to 1.000 x 1.000 inch in cross section. Stock sealed ball bearings are available in Conrad assembled deep groove radial ball bearings (Type C), and four-point contact radial bearings (Type X).
To realize the full benefits from anti-friction bearings, it is important to keep them clean and well lubricated. Seals and shields properly designed and mounted help to accomplish this. Integral seals and shields offer a very compact overall design with the additional advantage of protecting the bearing before, during and after installation.
