Bearings,as important components in contemporary mechanical equipment,mainly support the mechanical rotating body,which can reduce the friction coefficient during its movement and ensure its rotation accuracy.
The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages. There are two types of deep groove ball bearings: single-row and double-row.

6201ZZ (12x32x10mm) is a single-row bearing that supports radial loads, made with Chromium Steel providing superior quality and durability. It comes pre-lubricated and shielded to keep the lubricant in and contaminants, dirt and debris out.
Deep groove ball bearings were originally listed as radial ball bearings, which are the most widely used rolling bearings. It is characterized by low friction resistance and high speed.
