Metric Size Standard Miniature Ball Bearings S687

Metric Size Standard Miniature Ball Bearings S687

The S687 is a compact miniature ball bearing with a 7mm bore and 14mm outer diameter, crafted entirely from stainless steel for durability. Its slim 3.5mm width makes it ideal for tight spaces, while handling radial loads up to 202 lbf.

With a maximum speed of 36,000 RPM, it spins smoothly for small, high-speed applications. The open design allows easy lubrication, though regular maintenance is needed for optimal performance.

This bearing suits devices like small motors or precision instruments where space is limited. Weighing just 2.03g, it’s lightweight yet sturdy. Compliant with RoHS and REACH standards, it’s safe for various industrial uses.

The ABEC1 tolerance ensures reliable operation without excessive precision demands. Its 9-ball design balances load capacity and smooth rotation.
