Increased iron content makes these bearings stronger and more resistant to shock loads than standard oil-embedded bearings; however they operate at lower speeds.

Use these bearings for light loads and small shafts. The closed backing blocks out dust and other contaminants.

The flanged housing makes these bearings a good solution for vertical linear motion applications.

Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start.
