 Inch Size Miniature Flanged Ball Bearings feature an integrated flange on the outer ring for easy end-mounting and secure axial positioning without additional retaining components. Manufactured with chrome steel (AISI 52100) rings, they deliver high hardness, excellent wear resistance, and reliable fatigue life under moderate to high speeds and radial loads. Available in inch dimensions, these compact bearings are widely used in precision instruments, medical devices, small motors, robotics, and office equipment.

Inch Size Miniature Flanged Ball Bearings feature an integrated flange on the outer ring for easy end-mounting and secure axial positioning without additional retaining components. The contact rubber seal provides superior protection against dust, moisture, and contaminant ingress, making it well suited for harsh or dirty operating environments. Grease is fully retained within the bearing for reliable lubrication throughout service life. Available in inch dimensions, these compact sealed bearings are widely used in precision instruments, small motors, robotics, office equipment, and other applications requiring a clean, maintenance-friendly bearing solution.

Available in inch dimensions, these compact bearings are widely used in precision instruments, medical devices, small motors, robotics, and office equipment.

What lubrication is recommended for bearings with chrome steel balls?

Standard mineral or synthetic grease is recommended. Chrome steel balls perform well with most conventional bearing lubricants, and proper lubrication is essential to protect the ball surface and maintain service life.

Are sealed miniature flanged ball bearings suitable for wet or washdown environments?

Yes. The contact rubber seal provides effective protection against moisture ingress, making sealed bearings well suited for humid, wet, or occasional washdown conditions. For highly aggressive chemical environments, confirming seal material compatibility is recommended.

What are the key mechanical properties of chrome steel balls?

Chrome steel balls offer high hardness (typically 60–66 HRC after heat treatment), excellent surface finish, low surface roughness, and strong rolling contact fatigue resistance, all of which contribute to reliable and long-lasting bearing performance.
