Product Description1621-2RS Imperial Sealed Ball Bearing
The rubber seals on the ball bearing protect against the entry of dust and so on. This also helps to preserve the lubricant. These deep groove ball bearings are versatile, robust and relatively easy to maintain.
Imperial ball bearings are made in inches, which is useful to match previous British machines and present American ones with the right bearings.
