NTN Miniature Ball Bearings

Product Description

Miniature Ball bearings are sometimes referred to as instrument bearings or micro bearings which are very small machined components. These small bearings have an outside diameter of less than 3/8 inch (9.525 mm) or are small bearings with an outside diameter less than or equal to 1/2 inch ( 12.7 mm) having a ration of outside diameter to inside diameter equal to or less than two.

Miniature ball bearings are available in inch and metric sizes. With various design like open, sealed, shielded, flanged, with locating snap ring, with extended inner ring and thrust miniature ball bearing. Miniature ball bearings are useful in a wide variety of applications, including (but not limited to): 

• Fan motors
• Spindle motors
• Stepping motors
• Rotary encoders
• Dental handpieces
• Drills
• Medical devices
• Flow meters
• Fuel controls
• Gyros, synchros and servos
• Cryogenic coolers

Challenges of Miniature Ball Bearings

• Miniature ball bearings are highly engineered components that lower friction and enhance the operational life of the equipment. If attention is not paid to these small sized bearings, maintenance and flexibility can become challenges.
• The bearings must be maintained on a regular basis, so that they can maintain a smooth operation with a long life. The bearings must be lubricated regularly. The options for these small bearings can be hard to find, making it challenging to complete a working project. To eliminate these challenges, work with a supplier that has the options you need.
