lm25uu bearing

Lm uu bearing series are standard linear ball bearing widely used in the industrial application. The "LM" in the name stands for "Linear Motion," while "UU" indicates double-sealing features. These lm uu bearing and linear ball bearing are designed to comply with metric standards and feature a cylindrical outer tube, an inner retainer with steel balls, and dual-sealed retaining rings at both ends to securely fasten the retainer to the outer tube. This design of linear motion bearing and lm uu bearing ensures smooth and reliable motion control, making lm uu bearing and linear ball bearing stand out in various applications.

Advantages of lm uu bearing

  • High Precision and Low Friction: Lm uu bearings achieve linear motion through the rolling of steel balls, which have minimal friction resistance. This design of lm uu bearing results in high precision, low noise, and high rigidity even under heavy load.
  • Robust Construction: Lm uu bearings and sealed linear bearings are made from high-quality materials for the outer cylinder and balls, and plastic (Duracon M90 equivalent) for the retainer.
  • Versatility: Lm uu bearings and sealed linear bearings are suitable for a wide range of applications, including semiconductor manufacturing, food machinery, precision machine tools, and more.
  • Sealed Design: The double-sealed design of Lm uu bearings and sealed linear bearings helps prevent contamination and extends the service life of the bearings.

  • What are the load capacity and service life of the bearing?

    Load capacity is determined by dynamic (C) and static (C₀) load ratings. For example: A 6205 deep groove ball bearing has a dynamic load rating of 14 kN, suitable for small motors. For heavy loads, choose tapered roller bearings (e.g., 32208 with C=90 kN). Recommendation: Share your equipment’s load analysis for optimal bearing selection.

  • How to select bearings for wet/corrosive environments?

    Materials: Stainless steel (440C/316) or coatings (nickel plating, DLC). Seals: Double rubber seals (2RS) or PTFE seals. Example: Seawater pumps often use 316 stainless steel bearings with lifelong grease.

  • Will the bearing fail at high speeds?

    Speed limits depend on bearing type and lubrication: Standard 608ZZ ball bearings: ~18,000 rpm. Hybrid ceramic bearings (Si3N4 balls): 30–50% higher speeds. Solution: For high-speed applications, opt for oil lubrication or low-friction design.

  • How to estimate linear guide lifespan?

    Theoretical lifespan: Based on load calculations (see Q1). Real-world factors: Lubrication intervals (e.g., grease replenishment every 100km). Mounting surface flatness (≤0.01mm/m required). Tool: Free lifespan calculation software available.

  • Whatis the key parameters when replacing linear guides?

    Must-check: Slider hole spacing (e.g., 45mm×45mm). Rail width (15/20/25mm, etc.). Slider height (impacts machine space). Pro tip: Old slider model numbers are often engraved on the side.

  • Can I add my logo on the products ?
