1621-ZZ Imperial Shielded Ball Bearing
The metal shields on these imperial ball bearings are designed to offer protection against the entry of some dirt and so on. Shielded bearings also help to contain the lubricant/grease. They are versatile, robust and moderately easy to maintain.
They are well used in the agricultural industry, garden equipment, manufacturing and more. Bearings that are made in inches are really useful to match previous British machines and present American ones with the right bearings.
