What are Misalignment Spacers?

Misalignment spacers (also called eccentric spacers or adjustment shims) are precision-engineered components used to correct minor axial or radial misalignments between mating parts in mechanical assemblies. These spacers feature offset or tapered designs that allow fine-tuning of component positioning without requiring permanent modifications to the base structure.

Materials of Misalignment Spacers

1. Stainless Steel (304/316) – Corrosion-resistant for harsh environments.

2. Carbon Steel (Grade 1018/1045) – Cost-effective for general industrial use.

3. Aluminum (6061-T6) – Lightweight, ideal for aerospace/automotive.

4. Brass/Bronze – Low friction and wear-resistant for rotating parts.

5. PTFE-Coated Steel – Self-lubricating for high-wear applications.

Surface Treatments

• Zinc Plating – Basic rust protection (indoor/mild environments).

• Hard Anodizing (Aluminum) – Improves wear resistance.

• Black Oxide – Reduces glare and provides mild corrosion resistance.

• Electropolishing (Stainless Steel) – Smooth finish for cleanroom use.

• Powder Coating – Custom colors and added durability.

Specifications

• Types:

  • Eccentric Spacers (Offset bore for radial adjustment).

  • Tapered Spacers (Angular correction).

  • Slotted Spacers (Lateral adjustment).

• Size Range: 3mm to 150mm OD, with 0.1mm–5mm adjustability.

• Tolerances: Typically ±0.02mm for precision applications.

• Standards: DIN 988 (metric), ANSI B18.22.1 (imperial).

Applications

• Robotics: Aligning robotic arm joints for precision movement.

• Conveyor Systems: Correcting roller/pulley misalignment.

• Motoryzacja: Wheel hub centering, transmission assemblies.

• Aerospace: Engine mount adjustments.

• Medical Equipment: MRI/X-ray component alignment.

Excellent Case: Industrial Conveyor Belt Realignment

Challenge: A food processing plant experienced excessive belt wear due to a 2mm misalignment in the drive rollers, causing downtime and product spillage.

Solution:

• Installed stainless steel eccentric spacers (50mm OD, 0.5mm offset) on the roller shafts.

• Adjusted spacers to compensate for misalignment without disassembling the frame.

• Surface-treated with FDA-compliant electropolishing for hygiene.

Result:

• Belt Life Increased by 300% – Eliminated edge wear.

• Zero Downtime – Adjustment took <30 minutes vs. 4 hours for structural fixes.

• Hygiene Compliance – Met NSF/3A sanitation standards.
