Openbuilds C-Beam™ is a profile based on the V-Slot linear guide system. It incorporates a C shape profile which gives added strength and functionality. C-Beam™ is considered to be a 40mm x 80mm profile and as it is a product of the V-Slot line, all standard V-Slot parts and accessories are compatible.

C-Beam™ in available in 250mm, 500mm, 1000mm and 1500mm lengths and comes pre-tapped with 4 holes ready for C-Beam™ end mounts. This allows you to quickly create C-Beam™ linear actuators. Multiple plates can be added for prevision and strength.

C-Beam™ is a 6063 T-5 Aluminum Extrusion building block that has an extremely smooth linear v groove rail on all 4 sides. It's precise, easy to work with and allows you unlimited design control through it's modular nature. With a super smooth, clear anodized finish, making them much shinier than a standard T-Slot extrusion, the finish allows for a smoother ride for the OpenBuilds Delrin V Wheels.

The OpenBuilds Xtreme Solid V Wheel is part of the heavy duty Xtreme line of OpenBuilds parts, designed with strength in mind.

The Solid V Xtreme Wheel  is made from very hard polycarbonate (clear) material which, due to its strong nature, will resist compression and wear and, in turn, leads to better over all precision and strength for your builds.

The Xtreme V wheels are designed to be used as a heavy duty alternative to the Delrin V Wheels in applications such as CNC Routers/Mills where force and weight are introduced into the system. So, while the Delrin V Wheels work great for most light load applications the OpenBuilds Xtreme Solid V wheels can be used for builds where heavier loads are required and less compression in the delrin is desired.

The OpenBuilds Team have tested these wheels at 25lbs. per wheel with no noticeable deflection.  Beta testing resulted in unofficial results of 55lb.s per wheel!  Many of these wheels could be added to a gantry to allow an even distribution of the load across them.

These wheels are individually milled for consistent high precision and tolerance.

Part details:

• Material - Polycarbonate (clear)
• Dimensions 24.39 OD x 15.974 +/- 0.026 ID x 10.23 'thick'
• Rockwell Hardness M 75
• Compressive Strength 86Mpa

Xtreme Solid V Wheel Kit contains:

• 1 x Xtreme Solid V Wheel
• 2 x Ball Bearings - 625 2RS
• 2 x Precision Shim
• 1 x Lock Nut with Nylon Insert

Don't  forget to add screws and spacers to your order!

• M5 Low Profile Screw (25mm for use with 1/8" Plate and 30mm for 1/4" Plates)
• Aluminum Spacers (choose between 6mm and 1/4")
• Eccentric Spacers (choose between 6mm and 1/4")

Note: Usually for a standard gantry plate you will need two Eccentric Spacers as well as two Aluminum Spacers

IMPORTANT Only use silicone for lubrication on these polycarbonate wheels if needed.  DO NOT use synthetic lubricating oils or cutting oils.

These bearings can be used with the Threaded Rod Plate and 8mm ACME rod.

Mount with M5 x 8mm Low Profile Screws and Tee Nuts

Eccentric Spacers are the perfect solution for creating a pre-load from the V-Wheels to the V-Slot rail. They are added to one side of a set of wheels on a gantry plate.

The eccentrics give an approx 0.79mm adjustment range to allow for a very strong and secure connection between the V-Slot linear rail and wheel.  A 10mm flange allows for a very sturdy base for a stable wheel mount. These Eccentric Spacers come with a divot on the outside which allows you to know at all times where the smallest part of the cam hole is.

Product details:

• Stainless steel
• 8mm cam size
• 6mm - 1/4" cam height
• Rim fits into a 7.12mm hole
• 5mm Bore

An example steps settings for your control software would be 200 steps per millimeter if you are running the common 1.8 degree steppers and your stepper driver is set to 1/8 step mode. To calculate different step scenarios for your control software, have a look at these handy steps calculators!

Common setup example:

NOTE: Because this lead has 4 starts with 2mm pitch between each this means the pitch will be 8. So 8 is what you would use for the pitch setting in the steps calculators.
