LME20UU Linear Bearing – 20mm Shaft Diameter

LME20UU: 20x32x45mm

Robust Linear Motion for General Purpose Industrial Applications

The LME20UU linear bearing is engineered to deliver consistent, low-friction linear movement in a broad range of medium-duty industrial applications. Built following European metric standards, this bearing is fully interchangeable with other metric linear motion components, offering flexibility and ease of integration into new or existing systems. It features a 20mm inner shaft diameter, a 32mm outer diameter, and a total length of 45mm, making it a reliable choice for more demanding automation and motion control setups.

Versatile Performance Across Machines and Mechanisms

With its increased diameter and load-handling capabilities, the LME20UU is ideal for use in packaging machines, gantry systems, linear actuators, and various types of automated manufacturing equipment. Its size and rigidity provide the stability needed for higher loads and longer travel strokes, without compromising on precision or operational smoothness.

Designed for Stability, Longevity, and Low Maintenance

The bearing features a solid steel outer shell that is precision-ground and hardened for superior strength and wear resistance. Inside, a high-performance resin retainer maintains ball alignment and enables smooth recirculation, helping to reduce friction and mechanical wear over time. The precision-machined internal raceways support accurate, vibration-free motion under varying speeds and load conditions.

Dual rubber seals at each end of the bearing provide effective protection against dust, debris, and moisture, reducing the need for ongoing maintenance and extending service intervals. This makes the LME20UU especially suitable for semi-exposed industrial environments or systems that operate with minimal human intervention.

At 45mm in length, this bearing strikes the right balance between compact size and structural integrity, supporting consistent linear travel without adding unnecessary bulk to your machine layout. As part of the standardised European LME Series, the LME20UU can be confidently used across many industry platforms where metric compliance is essential.

LME20UU System Compatibility

Optimised for Kiwi Motion’s range of precision linear shafts—including the KM/W, KM-WRB, KM-WRA, and KM-WV series—the LME20UU offers a reliable and adaptable foundation for medium-load linear motion systems.
