FOCMKEAS Linear Roller Bearing LMF20LUU 20mm ID 32mm OD 80mm Length

Description

Product Overview

The FOCMKEAS LMF20LUU linear roller bearing is engineered for high‑performance linear motion. Constructed from hardened carbon steel, it provides excellent wear resistance and impact strength. Dimensions include an ID of 20 mm, OD of 32 mm, length of 80 mm, and a flange diameter of 54 mm with an 8 mm thickness. Five rows of steel balls create point contact, minimizing friction and ensuring smooth travel. Double rubber seals on both sides protect the internal lubricant from dust and moisture, extending service life in harsh environments.

Usage

This bearing is perfect for precision equipment such as 3D printing machines, CNC slide bushings, mechanical slides, and linear modules. It performs reliably in automated equipment, linear tables, and electronic assemblies where consistent, low‑noise motion is critical. Whether installed in a dusty workshop or a climate‑controlled lab, the double‑seal design maintains performance.

FAQ

What load capacities does the LMF20LUU support?

The bearing handles a dynamic load of 410 N and a static load of 590 N, suitable for most medium‑duty linear applications.

Can the bearing be used in humid environments?

Yes, the double‑seal design prevents water ingress, making it reliable in humid or slightly wet conditions.

Is the bearing compatible with standard CNC slide rails?

Its 20 mm ID and 32 mm OD match common CNC slide specifications, allowing easy integration.

How do I maintain the bearing for optimal performance?

Regularly inspect the seals for damage and keep the surrounding area clean; the internal lubrication is sealed for life under normal use.
