1502 Series 4mm ID Spacer (6mm OD, 4mm Length) - 4 Pack

1502-0006-0040 1502 Series 4mm ID Spacer (6mm OD, 4mm Length) - 4 Pack is a set of four 4mm thick aluminum spacers. These precision-machined spacers feature a 6mm outer diameter and a 4mm inner bore, designed to create consistent and repeatable clearance in mechanical assemblies. The 4mm thickness makes them especially useful for applications that require greater, yet precisely controlled, spacing between components.

Key Features:

• Extra Thickness of 4mm: Creates noticeable and functional clearance sufficient for free rotation of components, placement of other small components (such as retaining rings), or organization of an air channel for cooling.
• Standard Fit Dimensions: The 4mm inner diameter is compatible with standard sized axles and M4 screws. The 6 mm outer diameter corresponds to common seats in bearing blocks and mechanical assemblies.
• Lightweight and corrosion-resistant: Made of anodized aluminum, each bushing weighs only 0.16 g. Anodizing protects against oxidation and abrasion.
• High manufacturing precision: Guarantees that all bushings in a set are identical in length and geometry, which is critical for even load distribution when using several pieces in a single unit.
• Versatility: Ideal for:
  • Installation as spacers in bearing assemblies to set the correct axial clearance.
  • Positioning pulleys, gears, and couplings on shafts.
  • Assembling multi-layer structures and frames with a specified gap between levels.
  • Used as reliable and wear-free gaskets.
• Set of 4 pieces: Allows for symmetry and balancing in the mechanism by using bushings on several sides.

For whom: For designers, engineers and technical specialists who design and assemble precision mechanisms, gearboxes, robotic platforms and need high-quality, precisely manufactured components to control gaps and distances.
