E8 High-Speed Angular Contact Ball Bearing – 8×24×7mm Precision Magneto Bearing for Gyroscopes

Product Detailed Description

The E8 high-speed angular contact ball bearing (dimensions: 8 mm inner diameter × 24 mm outer diameter × 7 mm width) is a specialized miniature bearing designed for precision applications demanding high rotational speeds and compact design. Often referred to as a magneto bearing, it features a unique geometry: the outer ring has a single shoulder and a counterbored groove that merges smoothly with the raceway, allowing the outer ring to be separated from the inner ring and cage assembly. This design significantly simplifies mounting, disassembly, and maintenance—especially in tight spaces.

Commonly used in duplex pairs, E8 bearings can be preloaded or set with controlled end play to enhance rigidity and reduce vibration—critical for sensitive instruments like gyroscopes, small alternators, starter motors, and precision ball-screw end supports in CNC milling tables. The bore size range (typically 4–30 mm) makes the E8 model ideal for micro-mechanical and aerospace-grade components where space and weight are constrained.

As a cost-effective alternative to standard angular contact bearings in small-shaft applications, the E8 delivers high performance without compromising on reliability. Available under the YWS brand or OEM/ODM options, this bearing meets international quality standards and is suitable for global industrial, automotive, and instrumentation markets.
