 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 metal shield provides effective protection against dust and light contaminant ingress while maintaining low running torque and allowing higher operating speeds compared to contact seal configurations. Grease is retained within the bearing for reliable lubrication throughout service life. Available in inch dimensions, these compact shielded bearings are widely used in precision instruments, small motors, robotics, office equipment, and other applications requiring a clean, maintenance-friendly bearing solution.

Chrome steel balls deliver high hardness, excellent surface finish, and strong fatigue resistance, ensuring reliable performance under continuous operation at 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.

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.

What does the metal shield in a miniature flanged ball bearing do?

The metal shield acts as a barrier between the bearing interior and the external environment, protecting the rolling elements and raceways from dust and light contaminant ingress while retaining the internal grease lubrication.

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.
