Discover the Exclusive Ball Point Set Screw Feature in NTN Mounted Bearing Units

NTN’s unique ball point set screw design is a key feature in the success of our mounted units and your success while running your applications.

Enhanced Performance and Reliability

NTN’s innovative ball point set screw design is revolutionizing the performance of mounted bearing units. This unique feature includes a hardened steel ball (HRC 62) embedded in the end of the set screw, providing several advantages over traditional designs.

Superior Retention:

• The steel ball compresses into the tapered section of the set screw during tightening, causing thread expansion. This prevents the set screw from loosening under vibration and shock loads.

Increased Holding Force:

• Unlike cup point designs that cut circular grooves and reduce holding power, the ball point set screw ensures full transmission of force with a single point contact.

Reusable and Durable:

• The hardened steel ball maintains its shape and leaves only a small mark on the shaft, making it ideal for repeated use without damage.

Versatile Application:

• No need for a flat on the shaft, as the ball point set screw provides effective contact on any surface.

Reduced Fretting Corrosion:

• The hardened ball minimizes fretting corrosion compared to non-hardened cup point set screws.

Minimized Vibration and Noise:

• Set screws are spaced 120 degrees apart, ensuring three-point contact to reduce inner ring distortion and enhance overall reliability.

Upgrade your mounted bearing units with NTN’s exclusive ball point set screw for unmatched performance and durability.
