LME40UU Linear Bearing – 40mm Shaft Diameter

LME40UU: 40x62x80mm

Heavy-Duty Linear Motion for Industrial and Transportation Applications

The LME40UU linear bearing is engineered to deliver smooth, low-friction linear movement in demanding heavy-duty environments. Manufactured to European metric standards, this bearing offers full interchangeability with standard metric linear components globally. Featuring an inner shaft diameter of 40mm, an outer diameter of 62mm, and a length of 80mm, the LME40UU is built to support high loads and provide reliable motion in tough industrial settings.

Ideal for Transportation, Automation, and Heavy Machinery

With its robust design and high rigidity, the LME40UU is commonly used in transportation equipment, large CNC machines, packaging systems, and automated material handling. It ensures stable, vibration-free motion, making it suitable for applications requiring precise positioning under heavy loads and continuous operation.

Designed for Longevity and Low Maintenance

Constructed with a hardened, precision-ground steel outer shell, the LME40UU offers excellent resistance to wear and deformation under heavy usage. Inside, an industrial-grade polyamide resin retainer maintains smooth ball circulation, reducing friction and noise during operation. The precision-ground raceways contribute to low rolling resistance and quiet performance.

Dual rubber seals on both ends protect the bearing’s interior from contaminants such as dust, dirt, and moisture, greatly reducing maintenance requirements and extending service intervals. At 80mm in length, this bearing offers robust support while allowing for compact machine designs within larger assemblies.

As part of the European Metric LME Series, the LME40UU is fully compatible with metric shafting, making it a reliable and easily interchangeable component in a wide range of industrial applications.
