VXB 20mm Ball Bushing – SDM20GA Steel Retainer Linear Motion Bearing

1 / 3

Description

This here is a 20mm ball bushing from VXB, model SDM20GA, and it’s a linear motion bearing with a steel retainer – that means it’s tougher than the plastic cage versions, especially if you’re running high speeds or heavy loads.

It fits a 20mm shaft, so it’s a standard size for a ton of linear rails and rod setups.
The steel retainer keeps the balls evenly spaced, reduces noise, and handles side loads better than you’d expect.
It’s part of VXB’s Pack#12752, and it’s brand new, never used, still in its original packaging – though it might come in a plain box or bag, not a fancy retail blister pack.
No UPC on this one, but the MPN is Pack#12752, so you can match it to their catalog.
If you’re building a CNC, a 3D printer, a pick-and-place machine, or even a custom sliding door system, these bearings are smooth as butter.

They glide along hardened shafts with very little friction, and they’re easy to mount in standard bearing blocks.

Just make sure your shaft is clean and straight, and this bushing will last a long time.
VXB is a known brand in the motion parts world, so you’re not getting some no-name knockoff.
For the price, it’s a steal – grab a few and keep your linear motion buttery.
