Cold Drawn Steel Special Shape Spline Profiles For Splined Shaft

Splined Shafts for Rotary and Linear Motion, Standard Length Splined Shafts are made from Mild Steel, ideal for many repair jobs and building special machinery.  All stock splined shafts have a 2-3/4 inch working length except for full splines.  Additional materials available by request including 1045, 1144, 4140, 52100, EN8 etc

 

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.

Cold Drawn Steel Special Shapes

Machine shops put chips on the floor as a natural course of business.  As the material being machined gets more expensive, those chips get more expensive. We help eliminate the heavy external machining on steel bars by delivering near net or net shape profiles or special shapes to our customers.

 

During the cold drawing process, the special steel profiles are pulled through a series of dies to achieve the specific size and shape needed.

 

BENEFITS OF A SPECIAL SHAPE

Fushun Profiles’ custom cold drawn steel services have many benefits for your business. Special shapes allow our customers to skip the early machining steps, freeing up time, talent and money to focus on the end part they are making.

When you buy a special shape, you reduce your manufacturing cycle time and avoid paying for those chips on the floor.  Most of our customers report reduced inventory, reduced floor space and avoided capital and tooling investments because of buying special shapes from Keystone Profiles. Your cost goes down, and your time to market speeds up.

And, it is not just about the shape.  Surface finish, metallurgy, mechanical properties and length specifications are part of the special shape package.  You tell us what you need, and you get your special shape drawn to your exacting requirements when you need it.
