6011 ZZ bearings are a kind of common deep groove ball bearings with double-sided dust cover (ZZ), which are widely used in the fields of electric motors, automobiles, and industrial equipments, etc. Its structure is simple and stable, with high speed capability and low friction coefficient. It has simple structure, stable performance, high rotational speed capability and low friction coefficient. Meanwhile, the design of dust cover can effectively prevent dust and pollutants from entering into the inner part of the bearings and prolong the service life. The following is a detailed introduction of 6011 ZZ bearings:

1. Basic parameters of 6011 ZZ bearings

Model: 6011 ZZ
Inner diameter (d): 55 mm
Outer diameter (D): 90 mm
Width (B): 18 mm
Weight: approx. 0.43 kg
Material: Usually made of high carbon chrome steel (GCr15) with high hardness and wear resistance.
Seal type: Double-sided dust cover (ZZ), effectively preventing the entry of dust and contaminants.

2. 6011 ZZ bearing characteristics

High speed: the design of deep groove ball bearings makes them suitable for high speed operation, with low friction coefficient and low energy loss.
