LM Series LMS3 Linear Bearings LMS3UU Linear Ball Bearing Bushing LMS3F LMS3FUU for 3D Printer

The LMS3 Linear Bearing is a premium miniature linear ball bushing designed for precision linear motion applications requiring smooth, low-friction movement with high accuracy. This compact bearing (3×7×10mm dimensions) features a 4-circuit ball design, high carbon steel construction, and a resin retainer for optimal performance in tight spaces. Engineered to deliver consistent linear motion along cylindrical shafts, it's ideal for small-scale precision equipment where space is limited and accuracy is critical.

1. Ultra-Compact Design: 3mm bore size enables installation in the smallest precision instruments and devices
2. 4-Circuit Ball Configuration: Provides balanced load distribution, smooth motion, and improved rigidity compared to standard 2-circuit designs
3. High Precision Grade: Manufactured to tight tolerances for accurate positioning and repeatability in micro-movement applications
4. Low Friction Performance: Precision-ground raceways and high-quality steel balls minimize friction, extending component life and reducing energy consumption
5. Durable Construction: High carbon steel outer cylinder with resin retainer offers excellent wear resistance and dimensional stability
6. Easy Integration: Standard metric dimensions ensure compatibility with 3mm diameter linear shafts for seamless system integration

1. Q: What makes LMS3 different from standard LM3 linear bearings?

   A: LMS3 features a 4-circuit ball design (vs standard 2-circuit) for improved load distribution and rigidity, specifically engineered for high-precision miniature applications.

2. Q: Can LMS3 be used with stainless steel shafts?

   A: Yes, LMS3 is compatible with stainless steel shafts. For corrosive environments, consider our LMS3-S stainless steel variant (available upon request).

3. Q: Is the LMS3 available with seals or lubrication options?

   A: The standard LMS3 is open-type (no seals) for minimal friction. Sealed versions (LMS3UU with double-sided rubber seals) and pre-lubricated options are available for dusty or low-maintenance applications.
