Linear Motion Bearing LM16UU (16mm Dia)

Overview

The LM16UU is a compact, open-type linear ball bearing designed for smooth, low-friction motion along 16mm hardened steel shafts. Engineered for precision and durability, it's a staple component in CNC routers, 3D printers, and custom automation rigs. Its open design accommodates shafts with support rails, offering a flexible and cost-effective solution for your linear motion needs.

Key Features

• Smooth Linear Motion: Recirculating ball design minimizes friction for precise, consistent movement.
• Open-Type Design: Allows use with supported shafts, enabling longer travel distances without sag.
• Robust Construction: Hardened steel outer shell and precision-ground balls for extended service life.
• Compact & Lightweight: Easy to integrate into tight spaces and moving assemblies.
• Cost-Effective: Affordable alternative to linear rails for many DIY and prototyping applications.

Technical Specifications

• Inner Diameter (ID): 20mm (for 16mm shaft)
• Outer Diameter (OD): 28mm
• Length: 37mm
