Joe Its hard to say without seeing exactly what it is doing but this sounds like it could be a job for glass. We have been specializing in the manufacture of fan component parts, including fan shafts from our workshops in Birmingham for over 25 years. I am the product design responsible engineer on this project. Yeah, precisely, I use glass for all my drive shafts.

Some steel shafts are case-hardened with carbon or nitrogen.
At normal operating temperatures, the modulus of elasticity of alloyed steel is similar to that of carbon steel, so alloy steel is not suitable for increasing the rigidity of the shaft. These material property tables are especially useful when sourcing such materials as thermoset rubbers, urethanes, thermoplastics and especially the emerging thermoplastic elastomers for end products such as washers, bumpers, gel sheets, anti-vibration pads and others. Rotary shafts with break edges are deburred, but not chamfered. Rotary shafts are elongated, rod-shaped devices that rotate about a longitudinal axis and transmit torque. Depending on the job requirements, the spool axis plays the role of support reel, gear, and ratchet. Two major factors to assess in choosing the proper surface treatment are corrosion resistance and cosmetic improvement.
Shaft Materials: Although we endeavor to manufacture shafts from any type material specified by our customers, the majority of our shafts are manufactured from 3 main types of metal. If some kind of spec is saying you need more, then you need to fire your engineers and get ones that know what they are doing. Our Customers Leave Your Requirement In order to send correct and most suitable winch price and quotation, pls kindly offer some important info as below. Philabuster, You are indeed correct. Some rotary shafts have tapped or untapped axial holes for mounting to support structures. All, I am beginning the design of a drive shaft for a critical application.
I am not looking for anyone to specify a material for me. With respect to the analysis I have no problems. Applications: Our shafts are used for many specialist applications. The Rockwell hardness test presses a steel or diamond cone against a test sample and measures the depth of the resulting indentation. Hi, I am trying to select an alternative material to be used for a shaft that is currently made of H13 steel.
The second is in the area of wear resistance. Based on the description and internal cooling, I imagine shaft would look like an auger screw design. If the surface was not hardened properly in its manufacture, the ball bearings would quickly dent the surface of that material, effectively creating grooves along its surface of operation and range of motion. Higher measurements indicate harder materials. Stainless does indeed rust, but at a much slower rate than carbon steel, which begins to corrode literally as it is produced at the mill. Hard chrome plating will increase the surface hardness of the part and improve its corrosion resistance.
. I was trying to help the dude and if you'll notice I said it might not be an option because I don't know what its doing. The shaft will be located in an outside environment and unprotected. The surface hardness of the shaft should be about 55-57Rc. This becomes important for designers, especially when a much higher force is applied to a very small area. These are also readily available online nowadays, with a simple word search. H13 was the choice for higher temps such as molds and shot tips and sleeves 1325F alloy temp for but in the oven we found stainless to be a good cheap alternative-usually 316 or 304 was available and lasted well for many things.
Have such information on hand before making the materials selections of the components used. In such cases, the surface of the shaft material must be very hard to resist such pressure and thus allow the reliable and accurate operation of the linear bearing. For example, an engineer is seeking a precision linear shaft for use on an assembly. Pressure is force divided by area. The dimensions of the shaft are 1017mm 40. All have their function and a price point to consider, when designing. I read that as a coffee roaster.
Essentially, the chrome plating layer can handle the pressure, but the material underneath will remain too soft to support it. In many applications, this might not be a serious problem, if the part is to be covered with grease or oil, thus preventing severe exposure to the atmosphere and slowing down the corrosion process considerably. Ductile iron and some high-strength cast iron, cast because of good performance, easy to cast into complex shapes, and good damping properties, stress concentration sensitivity is low, the impact of fulcrum displacement is small, it is often used to create complex shape of the shaft. With respect to specifying basic mechanical properties of the material I need, I have no problem. Checkout the Shafting Data Brochure.
Whatever the application, the catalog information should be sufficient to assist the engineer in making this determination and thus drive the buying decision. How much slower the stainless rusts depends on its material grade 303, 304, 440 etc. Reel shaft material selection There are many kinds of materials in the shaft. In this job, the one thing I learned was how much continous high temperatures is like leaving steel out in the rain-it will oxodize. Height is the distance from the guide or rail base to the center of the guide or rail. Generally, this information will be included or available from the manufacturer.
It is not particularly durable and will usually wear off in use. Having worked in a motor diecast department where we used a lot of H13, I can say that at the temperatures that you are running, most common steels 4140, 4340 will start to corode very quickly. However, it will also wear over time in use.

Not recommended for anodising 5005 General purpose alloy for sheet metal work. As more exotic metal and composite materials come into use, this service is increasingly necessary, but will benefit the designer in many ways.
