About Shafts

About Linear Bearings

Splined on Both Ends

Splined End × Step-Down End

Grooves on the surface of these shafts transmit rotary power while allowing bearings to move freely along the length of the shaft. The edges are chamfered to remove sharp corners, reducing damage to bearings, housings, and other components during installation. All are turned, ground, and polished to tight diameter and straightness tolerances.

Four Splines

Shafts with four splines work with ball spline bearings, which create relatively little friction. They're commonly found in robotic and other automated systems that require complex, fast movements. They don't transmit as much torque as shafts with six splines.

All four-spline shafts are 52100 alloy steel for high strength. They're case-hardened to increase hardness and wear resistance on the surface of the shaft while allowing the center to remain soft for absorbing stresses caused by shifting loads.

Some of our four-spline shafts have a step-down end, which has been ground smooth and round like a standard shaft. Mount bearings, gears, and other round-bore components.

Six Splines

Large, evenly spaced splines transmit high-torque loads, such as those found in hydraulic systems, drivetrains, and machine tools. These shafts work with plain bearings, which means they're not meant for high-speed positioning applications. Made of 1045 carbon steel, they're strong but also machinable, so you can modify the ends to fit into your mounting fixtures. All meet ISO 14-B (formerly DIN 5463-B) to ensure they work with bearings that meet ISO 14-A.

Splined Rotary Shafts

Splined End × Straight End

With a splined profile on one end, these shafts transmit high rotational loads—good for hydraulic systems, machine tools, and other high-torque applications. Compared to keyed shafts, they last longer, handle higher torque, and do not require as tight of a fit. Shafts are 1045 carbon steel, a general purpose shafting material that balances high strength and good machinability. They are 48" long and have six 12"-long splined grooves on one end. The straight end is turned, ground, and polished for a smooth, round finish. The edges are chamfered to remove sharp corners, reducing damage to bearings, housings, and other components during installation.

Mounted Linear Bearings for Spline Shafts

A flanged housing with mounting holes connects these bearings directly to your system. They have a grooved inner diameter that's designed to work with spline shafts. Together, they transmit rotary power while allowing the bearing to move freely along the length of the shaft. Wide and flat, the flange is especially useful for lifting and lowering loads on vertical shafts. All are for use where shaft misalignment is unlikely.

Also known as ball splines, ball bearings run with less friction than plain bearings, so they're smoother and more precise, even at high speeds. However, they don't transmit as much torque as plain bearings. They're commonly used for robotic systems and other automated applications that require complex, fast movements. Bearings with stainless steel balls are more corrosion resistant than bearings with steel balls.

Plain bearings have evenly sized and spaced splines for transmitting high rotational loads, such as in hydraulic systems, drivetrains, and machine tools. They don't run as smoothly or as fast as ball bearings, though. All meet ISO 14-A (formerly DIN 5463-A) to ensure they work with shafts that meet ISO 14-B.

Linear Bearings for Spline Shafts

With a grooved inner diameter, these bearings are designed to work with splined shafts. Together, they transmit rotary power while allowing the bearing to move freely along the length of the shaft. All are for use where shaft misalignment is unlikely.
