LME12UU Closed Linear Bushing For 12mm Linear Shaft Rail

LME12UU Linear Bearing – 12mm Shaft Diameter

LME12UU: 12x22x32mm

Reliable Linear Motion for Light-to-Medium Duty Applications

The LME12UU linear bearing is a versatile and compact solution for precise linear motion in a variety of automation and machinery applications. Designed and manufactured to European metric standards, it offers full interchangeability with standard metric systems, making integration into new or existing assemblies simple and straightforward. This bearing features an inner shaft diameter of 12mm, an outer diameter of 22mm, and an overall length of 32mm. It is ideal for systems that require a combination of low friction, compact design, and long service life.

Designed for Versatility Across Industries

Due to its balance of size and strength, the LME12UU is widely used in applications such as pick-and-place machines, small CNC equipment, inspection systems, and automated assembly stations. It provides stable, vibration-free motion that supports consistent positioning and high repeatability, even in demanding production environments.

Built to Perform with Minimal Maintenance

The LME12UU is built with a robust, hardened steel outer shell that resists wear and deformation under repeated use. Its closed-end construction includes rubber seals on both sides, which prevent the entry of dust, debris, and moisture into the bearing track. This feature significantly extends the operational life of the bearing and reduces downtime related to cleaning or relubrication. Inside, an industrial-grade resin retainer ensures proper circulation of the bearing balls while maintaining spacing, contributing to smooth, low-friction movement.

The bearing’s internal raceway is precision ground, minimizing rolling resistance and operational noise. This results in cleaner, quieter motion that is ideal for use in applications where both accuracy and user comfort are important. With an overall length of just 32mm, the LME12UU fits easily into compact linear systems without sacrificing stability or load capacity. Its compliance with European metric sizing ensures compatibility with a wide range of motion components and shafting systems.

LME12UU System Compatibility

Engineered for a precise fit with Kiwi Motion’s range of linear shafts, including the KM/W, KM-WRB, and KM-WV series, the LME12UU offers reliable performance in light-to-medium duty systems. It’s an excellent choice for engineers seeking a dependable, low-maintenance linear bearing for automation, manufacturing, or technical applications.
