FAQ

What is the load capacity of the LM20UU bearing?

The LM20UU is rated for moderate radial loads typical of precision linear motion systems. Exact capacity depends on operating speed and lubrication, but it comfortably handles the demands of most CNC and 3D printing setups.

Can the bearing be used in wet or humid environments?

Yes. The double‑sealed construction and nickel plating protect the internal balls from moisture, making it suitable for humid or lightly wet conditions.

Is additional lubrication required?

The bearing comes pre‑lubricated for standard use. For extreme loads or high‑speed applications, periodic re‑lubrication with compatible grease can extend service life.

What sizes are available?

The LM20UU model is fixed at a 20 mm bore. However, HiPicco offers a full range of linear bearings in various bore and outer diameters to match different system requirements.

How does the nickel plating affect performance?

Nickel plating enhances surface hardness and corrosion resistance, allowing the bearing to operate reliably in environments with chemicals, elevated temperatures, or exposure to moisture without degrading.
