Low-Noise 25×40×59 mm Double-Sealed LM25UU Linear Motion Ball Bearing for CNC 3D Printer

LM25UU Linear Motion Ball Bearing: Reliable Precision for Automated Systems

For engineers, OEMs, and automation specialists, the LM25UU Linear Motion Bearing is an essential component for building accurate and reliable linear motion systems. As part of the widely adopted “LM” series, it offers a standardized, cost-effective solution for converting rotary motion into smooth, low-friction linear travel along a hardened steel shaft (linear guide rail).

Características clave:

• Low Friction & Smooth Motion
  The linear motion bearing utilizes multiple rows of recirculating ball bearings, resulting in extremely low friction coefficients. This allows for smooth, precise, and effortless movement of the carriage along the shaft, which is critical for accuracy in automation.

• High Rigidity & Load Capacity
  Despite its compact size, the LM25UU is designed to offer good radial load capacity and rigidity, minimizing deflection under load and ensuring precise positioning.

• Excellent Durability & Long Life
  The hardened steel construction of both the bearing and its mating shaft provides exceptional resistance to wear. The sealed design protects the internal components, extending service life even in moderately dirty environments.

• Standardization & Ease of Use
  As a standard component, the LM25UU is easy to source, design with (using readily available CAD models), and integrate. It is compatible with a wide range of standard pillow blocks, mounting blocks, and 25mm linear shafts.
• Cost-Effective Solution
  It provides an optimal balance of performance, reliability, and cost for countless linear motion applications, making automation projects more feasible.
