Introducing the X-50 Stiffy

Onefinity is excited to announce the X-50 Stiffy.

Take your Onefinity to another level with the simple to install, beefy X-50 Stiffy. Although the Onefinity X-50 models are very rigid, when using an 80mm Spindle with large bits the X-50 Stiffy is a great add-on to ANY X-50 model.

X-50 Stiffy features:

50mm Hollow Linear Rail Shaft for maximum rigidity

High Load Linear Roller Bearing

Precision machined Aluminum Gantry Block and Rail Ends

Engineered to be rigid: no sagging

Simple installation: Only 6 Bolts total

For more info please check out the QCW Frame video:

Important: The X-50 Stiffy will go on sale November 28, 2022. First orders will start shipping in 4-6 weeks.

Be safe, be well, and stay tuned for our next announcement tomorrow! 😊
