LMH…UU Oval Flange Linear Ball Bearings

The LMH…UU Series Oval Flange Linear Ball Bearings are designed for applications that require compact installation, stable support, and smooth linear motion.
Compared with square or round flange bearings, the LMH oval flange features two mounting holes, allowing easy installation in tighter spaces while maintaining excellent structural rigidity.
This bearing is engineered for use with hardened and ground linear shafts, delivering low-friction, precise, and stable motion across a wide range of automation and industrial applications.

Description

Product Overview
The LMH…UU Series Oval Flange Linear Ball Bearings are designed for applications that require compact installation, stable support, and smooth linear motion.
Compared with square or round flange bearings, the LMH oval flange features two mounting holes, allowing easy installation in tighter spaces while maintaining excellent structural rigidity.
This bearing is engineered for use with hardened and ground linear shafts, delivering low-friction, precise, and stable motion across a wide range of automation and industrial applications.

Key Features
Compact Oval Flange Design
The LMH flange provides secure mounting with fewer bolts, ideal for limited-space applications.
Smooth and Precise Linear Motion
Precision-ground raceways and hardened steel balls ensure low noise, low friction, and consistent accuracy.
Durable Bearing Steel Construction
Hardened GCr15 material provides excellent wear resistance, even during continuous operation.
Easy Installation and Alignment
Two-hole oval flange simplifies mounting, making it suitable for lightweight machinery and compact modules.
Available in a Full Metric Range
From 6 mm to 60 mm shaft sizes, fitting both small precision instruments and large industrial machines.

Typical Applications
LMH…UU oval flange linear bearings are commonly used in:
3D printers and laser engraving machines
