Low-Carbon Steel Rectangular Tubes

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. These tubes are often fabricated into parts that don’t require high strength, such as frames, supports, and raceways. To increase their wear resistance, you can surface harden them with heat treating. These tubes are manufactured to ASTM or EN standards for quality and performance.
Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

Linear Motion Shafts with Material Certification

For your compliance and quality assurance needs, these shafts come with a material certificate with a traceable lot number. These shafts work with linear bearings to reduce friction in manual and automated systems, such as packing, machine tool, and material handling operations. All are turned, ground, and polished to tight diameter and straightness tolerances. This allows them to evenly distribute loads, reduce vibration, and improve accuracy and stability.
Made from carbon steel, they’re strong and good for general purpose use. Their surface is hardened while the center remains soft enough to absorb stress from shifting loads. All have chamfered edges to remove sharp corners, reducing damage to bearings, housings, and other components during installation.
Surface smoothness—The lower the microinch value, the smoother the finish and the less friction and wear it will cause on the bearing.
