13 best linear motion bushing shafts
Linear motion bushing shafts are essential components in various industrial and mechanical systems, particularly in applications that require smooth and precise linear motion. These components are often used in conjunction with linear ball bearings and other linear motion products to facilitate smooth and frictionless movement along a straight path. Here is some information about linear motion bushing shafts:
Function: Linear motion bushing shafts provide a stable and guided path for linear motion components like linear ball bearings or linear bearings. They support and guide the movement of these components, ensuring they move accurately along the shaft's length.
Materials: Linear motion bushing shafts are typically made from high-quality materials such as steel, stainless steel, or aluminum. The choice of material depends on the specific application and environmental factors, such as corrosion resistance requirements.
Surface Finish: To reduce friction and wear, linear motion bushing shafts often have a precision-ground or polished surface finish. This ensures that the linear bearings or ball bearings can smoothly glide along the shaft.
Shaft Diameter: The diameter of the shaft is a critical factor in determining load capacity and rigidity. Smaller shafts are suitable for lighter loads, while larger-diameter shafts can handle heavier loads without deflection.
Shaft Length: The length of the shaft varies depending on the application. It can be customized to meet specific requirements.
Mounting Options: Linear motion bushing shafts can be mounted horizontally, vertically, or at various angles, depending on the application's needs.
Alignment and Tolerance: Proper alignment and tolerance control are essential when installing linear motion bushing shafts. Misalignment can lead to premature wear and reduced performance.
Lubrication: Adequate lubrication is crucial to reduce friction and ensure smooth linear motion. Some linear motion bushing shafts have built-in lubrication systems, while others require periodic manual lubrication.
Applications: Linear motion bushing shafts are widely used in industrial and scientific applications, including CNC machinery, automation systems, conveyor systems, 3D printers, and more.They play a fundamental role in ensuring precise and controlled linear movement.
Maintenance: Regular maintenance is necessary to extend the lifespan of linear motion bushing shafts. This includes cleaning, inspection, and re-lubrication as needed.
In summary, linear motion bushing shafts are vital components in linear motion systems, providing a reliable and guided path for linear motion bearings and helping to ensure smooth and precise movement in a wide range of industrial and scientific applications. Proper selection, installation, and maintenance are essential to maximize their performance and longevity.

User questions & answers
| Question: | so if i order 3 rods of different lengths, but do so all in one order, the shipping is $4 for all of them |
| Answer: | I replaced this fan and air king 50 in my 20 years old appartment bathrooms.Previous fan had same installation braket. Hardest part were remove old one and not damage ceiling, because this braket works only one way in. To get it out you I had to brake old fan case. And another hard part is slide new fan case in opening with exaust pipe in. You have to play with it. It ll be easy if you remove motor and fan blades before installation and after you attached exaust hose check louver inside if it is able to open and close. |
| Question: | Is the material magnetic |
| Answer: | Yes. The fan comes with all you need (bracket, fan, instalation screws and electrical caps to co nect wires) , but I used old caps and screws. I have 2 fans one cfm 70 in one bathroom and cfm 50 in another one. Both have 4" housing diameter. In one bathroom I had 5 " pipe and I ducttaped it to connected fan and pipe. Both fans are really quiet. Some time is really hard to notice that they work. |
| Question: | Can I order this 20mm at 1828mm in length? I need 6 of them, thanks |
| Answer: | It could be mounted inside a 2"x6" wall. The fan will not fit in most walls, which are 2"x4" studs. I replaced an Air King 50-CFM fan that was wall mounted, even though I moved the fan to the ceiling. I find the ceiling installation more effective for keeping the moisture moving out during and after a shower. |
| Question: | Your listing says 8mm but there are no product options smaller than 10mm. Where are your 8mm rods |
| Answer: | Hi, I don't know which one is right, because I don't have devices to check it, but I have this one in one bathroom and another one BFQ 70 in the other bathroom, which is rated everywhere 2.5 Sones. And I can say this one is quieter than BFQ 70 and I can barely here him. |

User questions & answers
| Question: | what is the spacing between holes on the rod supports? Ctr to Ctr |
| Answer: | There is no need for a battery it works with the sun but only with the sun. It turns off once in shade. You can install a battery but its on your own terms they do not help but they did indicate to me that people have added a battery for their fans to keep them running 24 hours |
| Question: | what size mounting screw do these take |
| Answer: | The cut out per the manufacturer installation instructions requires 14 to 19 inch circular opening and state to not cut through any framing members. |
| Question: | what is the vertical center from base of supports |
| Answer: | I had a high powered electric fan, so the fact that it stopped using electricity is a savings, but it cost $250 more, so it would take a year or two to pay off the difference, if the fan took 50 cents to operate per day on hot days. If this is not going to be a replacement, it should make a much larger impact on keeping the house cool and saving energy. |

User questions & answers
| Question: | can I weld this steel |
| Answer: | I used a cutting torch no problem, I think this rod is mild steel |
| Question: | How easy is it to cut and drill, torch or hack saw |
| Answer: | I used 4 pcs 5/8" dia. for axles for my 400lb welding machine and they bent a little. I think 3/4" would have been better for my application. My best guess is about 200lb for 1" dia. for a point load without deformation if the materials are the same. If you weld or heat it good, that will change. I am not an engineer. |
| Question: | On a piece with a 1-inch diameter how much weight can this hold with a 6 and 9/16 Tang sticking out unsupported |
| Answer: | it would work fine use collar locks for wheels or drill 1/8 hole for cotter pins |
| Question: | Would this work for an axle with 2 NEW 10" AIR Tires Wheels 5/8" on a surf fishing cart made of sch40 pvc |
| Answer: | I'm sure that it can with the correct sure I'm sure it can with the correct die, but why not just but a threaded rod. |
