Perfect for CNC Upgrade

These bearings smoothed out the motion on my milling machine significantly. The locking mechanism is secure and easy to adjust.

Great for 3D Printer Frames

We used the SCS20 model for our large format printers. The box-type housing makes mounting very straightforward compared to standard blocks.

Solid but tight fit

Quality seems high. The fit on the shaft was very tight initially, required some gentle tapping to seat properly. Once installed, no issues.

Good value for industrial use

Solid construction and good tolerance. Took a little bit of break-in time before movement was completely silent, but works well now.

Reliable under heavy load

Using these on a linear actuator for automation. They handle the radial load without any play. Highly recommend for serious builds.

5 FAQ

Q: Is the SCS20 compatible with a 20mm smooth rod?

A: Yes, the SCS20 is specifically designed for 20mm diameter linear shafts. Ensure the shaft is hardened for best results.

Q: How well do the seals protect against metal chips?

A: The double rubber seals provide good protection against dust and small debris. For heavy chip environments, additional way covers are advised.

Q: Do I need to add more grease upon arrival?

A: The units come pre-lubricated. However, regular maintenance lubrication is recommended after every 500km of travel or annually.

Q: What is the warranty period for these bearing housings?

A: All our bearing units come with a standard 1-year manufacturer warranty against defects in material and workmanship.

Q: What hardness should the linear shaft be for these bearings?

A: We recommend using hardened linear shafts with a hardness of HRC 50 or higher for optimal lifespan and performance.
