Q: How much weight will linear bearings support if they are attached to the underside of a beam?

A: We strongly suggest that linear bearings NOT be used in this configuration.


Q: Do you offer extrusions in different colors?

A: 80/20 offers T-slotted extrusions in custom anodized colors (clear is standard) for an additional charge. Custom anodized or powder coated product will be quoted upon request.


Q: How many different sizes of T-slotted profiles do you offer?

A: 80/20 Inc. stocks 27 Fractional T-slotted profiles and 27 Metric T-slotted profiles. 80/20 Inc. is currently the only extrusion company to offer both fractional and metric extrusions. The sizes range in fractional from 1/2" x 1" (1050) to 3" X 6" (3060).


Q: What is the difference between the 10 Series and 15 Series T-slotted extrusions?

A: 10 Series extrusions are designed on 1/2" and 1" dimensions. 1/2" from the center of the T-slot to the edge of the extrusion. 1" center to center of T-slots. Our 1020 extrusion is 1.0 x 2.0 inches. 15 Series extrusions are designed on 3/4" and 1.5" dimensions. 3/4" from the center of the T-slot to the edge of the extrusion. 1.5" center to center of T-slots. Our 1530 extrusion is 1.5 x 3.0 inches.


Q: Do any connections have a locking mechanism so that the connections hold tight even when subjected to movement or vibrations?

A: The locking mechanism is in the design of the T-slotted profile. The T-slot flange declines two degrees in towards the center of these profiles. This "Drop Lock Feature" acts as a lock washer in that it spring loads the fastener as it is tightened.


Q: What are your stock lengths of extrusions?

A: While not all profiles are available in all lengths, most Fractional T-slotted extrusions are available in 145-inch and 242-inch stock lengths. A few are also available in 97-inch stock lengths. Most Metric T-slotted extrusions are available in 4-meter and 6-meter stock lengths. Consult the current 80/20 Catalog for profile stock length specifics.


Q: How much weight will your extrusions support?

A: In most applications load requirements can be met by selecting the proper profile(s), fastening method(s), and design details. Call us if you have an application-specific question at 847-228-0400.


Q: What is the alloy used in your T-Slotted aluminum extrusions?

A: We use 6105-T5 aluminum alloy because of its higher ultimate and yield tensile strength.


Q: What is the yield strength of this material?

A: 80/20's T-Slotted aluminum profiles have a yield strength of 35,000 lbs./ sq. in. minimum.

Q: Are the Tap Extrusion Ends services (ex. 7060) for one or both ends of the extrusion?

A: Tap extrusion ends services are for one end. You can specify different tap sizes at opposite ends of the same extrusion.
