Precision LM16UU closed linear bearing with dual seals AI-Powered Review

Technical Description & Applications of LM16UU

The LM16UU is a sealed linear ball bearing designed for 16 mm shafts. The UU designation means it includes dual side sealing, protecting internal components from dust, debris, and external contaminants.

Key features & benefits

• Closed design (UU) - sealed both sides, no open gaps

• Low friction - friction coefficient around 0.001-0.005

• Operating temperature range - from -20 °C to +80 °C

• Max linear speed - approximately 5 m/s under suitable lubrication

• Standard dimensions - bore 16 mm, outer 28 mm, length 37 mm

• Load ratings - example: 780 N dynamic, 1190 N static

Typical applications

Common uses of LM16UU include:

• CNC machines and machining centres

• Industrial automation systems

• Robotics and linear motion frameworks

• 3D printers and DIY precision modules

Mounting and maintenance advice

• Use shafts in tolerance h6 and good surface finish (~0.3 µm Ra)

• Ensure components are clean before assembly

• Factory grease reduces need for frequent re-lubrication

• In harsh environments (dust, moisture), consider additional sealing or upgraded variants
