1502 Series 4mm ID Spacer (6mm OD, 1mm Length) - 4 Pack

1502-0006-0010 1502 Series 4mm ID Spacer (6mm OD, 1mm Length) - 4 Pack is a set of four ultra-thin aluminum spacers with a minimum thickness of 1 mm. Weighing just 0.04g each, these 6mm OD, 4mm ID bushings are designed for precise adjustment of microscopic clearances in high-precision mechanical assemblies.

Key Features:

• Minimum Thickness (1mm): Designed for situations where the smallest possible increase in distance between components is required, such as eliminating minimal backlash, fine-tuning gear mesh, or ensuring minimal clearance for free rotation.
• Precision Made: Machined from precision-machined aluminum to ensure consistent thickness and plane alignment, critical for such thin components.
• Standard Dimensions: 4mm ID compatible with M4 axles and screws. The 6mm outer diameter is standard and often matches machine seating positions.
• Lightweight: Their extremely low weight makes them ideal for applications where every gram counts, such as competitive robotics or aeromodelling.
• Set of 4: Allows for fine adjustment at multiple points simultaneously or to have a reserve.
• Versatility: Used for:
  • Precise axial adjustment of rolling bearings.
  • Adjusting backlash in gear drives.
  • Creating a shim stack of the desired overall thickness.
  • Compensating for manufacturing tolerances when assembling precision mechanisms.

For whom: For engineers, designers and craftsmen working Over the assembly of high-precision devices, where calibration down to fractions of a millimeter is crucial. This is a tool for the final, "precision" finishing of mechanical components.
