Metric Size Standard Miniature Ball Bearings S624

Metric Size Standard Miniature Ball Bearings S624

The S624 is a compact miniature ball bearing with a 4mm bore and 13mm outer diameter, crafted entirely from stainless steel for durability. It handles radial loads up to 224 lbf and spins smoothly at high speeds, reaching up to 36,000 RPM.

Its open design allows for easy lubrication, while the stainless steel cage ensures reliable performance. The bearing operates well in temperatures ranging from -30°C to 110°C.

With a lightweight build at just 3.1g, it’s ideal for small, precision applications like model making or miniature machinery. Compliant with RoHS and REACH standards, it’s a safe and versatile choice for various lightweight projects.

The ABEC1 tolerance and MC3 radial clearance make it suitable for applications where moderate precision is needed without excessive friction.

Application

Common Applications of S624 Bearing
S624 Bearing is widely used in small electric motors, such as those found in cooling fans and power tools, thanks to its compact size and reliable radial load capacity. The stainless steel construction ensures durability even in damp or corrosive environments.

Where Is S624 Bearing Used?
You’ll often spot S624 Bearing in precision instruments like dental drills or laboratory equipment, where smooth rotation is essential. Its ABEC1 tolerance class makes it suitable for applications requiring consistent performance without excessive noise.

Built for Versatility: S624 Bearing
In automation systems, S624 Bearing fits neatly into robotic arms and small conveyor mechanisms, handling moderate loads with ease. The open design simplifies lubrication, extending its service life in continuous operation.

Medical vs Industrial: Where S624 Bearing Excels
While S624 Bearing performs well in industrial settings like textile machinery, it’s equally at home in medical devices such as handheld scanners. The stainless steel materials meet hygiene standards while resisting wear.

Light-Duty vs Heavy-Duty: Best Uses for S624 Bearing
S624 Bearing shines in light-duty applications like model-making or small appliances, where its 4mm bore is ideal. For heavier tasks, it’s often used in clusters to distribute loads across multiple units.
