Metric Size Standard Miniature Ball Bearings 636

Metric Size Standard Miniature Ball Bearings 636

The 636 is a small, open-type radial ball bearing measuring 6mm in bore, 22mm in outer diameter, and 7mm in width. Made from chrome steel, it handles radial loads up to 637 lbf and spins smoothly at speeds up to 30,000 RPM.

Its single-row design with a stainless steel cage offers reliable performance, while the open seal allows easy lubrication. The bearing operates in temperatures from -30°C to 110°C.

With an ABEC1 tolerance class, it suits general-purpose applications where moderate precision is needed. Ideal for small machinery, electric motors, or hobbyist projects.

Weighing just 13.9 grams, it’s lightweight yet durable. Compliant with RoHS and REACH standards for safe use.

Features

Why Choose 636 Bearing for Precision Tasks?

636 Bearing is precision-engineered with chrome steel rings and balls, ensuring smooth radial movement.

Its ABEC1 tolerance class guarantees consistent performance in applications requiring accuracy.

The stainless steel cage maintains ball alignment, reducing friction and wear.

With a maximum speed of 30,000 rpm, it offers both precision and efficiency.

Application

Key Fields for 636 Bearing
In industrial settings, 636 Bearing is commonly used in small electric motors and gearboxes due to its compact size and reliable radial load capacity. The open design simplifies lubrication, extending service life in continuous operation.

Where Is 636 Bearing Used?
You’ll often find 636 Bearing in automotive applications like dashboard instruments or small actuators, where its 6mm bore fits neatly into tight spaces. Its ABEC1 tolerance ensures smooth rotation without excessive noise.

Perfect Fit for Automation: 636 Bearing
This bearing works well in robotic joints and 3D printer assemblies, thanks to its lightweight construction and stainless steel cage. The 30,000 rpm rating handles high-speed movements with ease.

Medical vs Industrial: Where 636 Bearing Excels
While 636 Bearing suits lab equipment like centrifuges, it’s equally handy in conveyor belt rollers. The chrome steel rings resist wear in both sterile and dusty environments.

Consumer Electronics and 636 Bearing
Inside desk fans or handheld tools, 636 Bearing provides quiet operation with minimal maintenance. Its 7mm width fits neatly into slim housings without compromising performance.
