Linear Motion Bearings
⚙️ What Are Linear Motion Bearings?
Linear Motion Bearings are mechanical components designed to support and guide motion along a
straight path with
minimal friction.
They are widely used in
automation,
CNC machines,
robotics,
3D printers,
packaging equipment, and
precision instruments.
- 🔩 LM Series – basic straight cylindrical linear ball bearing
- 🛡️ Available with or without seals (e.g., UU sealed)
- ⚙️ Standard type for general linear guide applications
- 📏 Available Sizes: LM6UU, LM8UU, LM10UU, LM12UU, LM16UU, LM20UU, LM25UU, LM30UU, LM35UU, LM40UU
LM Bearing Variants (LUU, Flanged, Square & Oval Flange)

Easy Mounting
Product Overview
Linear Motion Bearings are available in multiple configurations to suit different mounting
and load requirements. Variants such as LM-LUU (Long Type),
Flanged Bearings, Square Flange Bearings, and
Oval Flange Bearings offer improved stability, easier installation, and
reliable performance in precision linear motion systems.
