693 ZZ Mini Ball Bearing Shielded R830ZZ

693 ZZ is a precision miniature ball bearing manufactured with a metal shield on both sides and pre-greased so that it is delivered ready for use. Constructed of bearing steel, it is a 690 series miniature ball bearing for normal duty applications. Yuanhe’s 690 series miniature ball bearings have a larger outside diameter for high speed and higher load capacity applications.

The bearing is a high precision premium shielded miniature ball bearing. What sets this 693 ZZ bearing apart is that it meets ABEC-3 precision standards, uses Class 10 balls, and has an excellent Electric Motor Quality Class (EMQ).

693 ZZ miniature bearings are widely used in industrial and scientific applications such as medical and industrial handpieces, flow meters, fuel controls, gyroscopes, synchronizers, servo systems, electric motors, cryocoolers, pulmonary assist devices, etc.

● Small diameter sizes are available

● Suitable for high speed rotation

● Premium quality precision ball bearing

● Electric motor quality rated (EMQ)

A miniature ball bearing is a small rolling bearing that uses balls to separate two “races” or bearing rings. The main difference between these bearings and many others is their small size, allowing them to be used in smaller and more compact light-duty applications. The combination of balls and bearing rings helps reduce surface contact and rotational friction on the plane of motion to accommodate axial loads.

Miniature ball bearings help facilitate motion by distributing loads and reducing friction in applications with high-speed requirements, ultimately helping to extend equipment life while also being effective space savers in compact applications.

Other types of ball bearings are also available: 6309 ZZ, 6309 2RS, 6308 2RS, 6307 2RS, 6304 2RS, 628 2RS. If you’re interested in our procucts, please feel free to contact us.
