Number of Pieces
Piece Length in mm

This shaft is made of 1045 carbon steel, precision ground to exactly 25mm, and chrome plated. The production process is the same as linear shaft - except the shaft is not case hardened, allowing you to easily drill and machine the shaft. This shaft has a keyway machined into the entire length. 25mm is one of the 'core' shaft diameters in our mechanical product line - in addition to 8mm, 12mm and 17mm. 25mm is ideal for heavy duty #40 chain systems. We also sell the 25mm shaft without a keyway.

    • Shaft Couplers

    If you need to connect this shaft to a motor or another device with a shaft, you can use a shaft coupler:

    Pulleys and Sprockets

    If you're using a rotary system that requires a lot of torque, you may be interested in pulleys and sprockets. By using a two pulleys or sprockets of different sizes, you can increase the gear ratio of the system. Pulleys and sprockets can also be used to transmit rotation over a long distance. For more guidance on building a transmission system, visit our Rotary Motion Primer. Here is a list of our 25mm bore pulleys and sprockets:

    TRM4156_0 $8.00 25 mm 40
    TRM4157_0 $13.35 25 mm 60

    Rotary Bearings

    Systems with heavy loads or pulley/sprocket assemblies often put a lot of sideways strain on the shaft. In such a system, you can use rotary bearings to protect and support the shaft:
