  2. Long Description 

  Our high-precision Stainless Steel Thin Flat Washers are more than just standard washers; they are engineered shims designed for critical applications where accuracy and durability are paramount. Manufactured from high-quality AISI 304 Stainless Steel, these shim rings offer superior resistance to rust and corrosion, making them the ideal choice for the automotive, aerospace, marine, and food processing industries.

  These versatile shims are primarily used as Bearing Shims to accurately set and adjust axial clearance (pre-load) in bearing assemblies, ensuring optimal performance and extended bearing life. Their thin, flat profile also makes them perfect for use as general-purpose spacers, gaskets in low-pressure systems, and alignment shims in machinery to compensate for wear and manufacturing tolerances.

  Whether you are performing a precise repair, building a prototype, or maintaining industrial equipment, our shim washers provide the reliable, consistent thickness you need to achieve a perfect fit and flawless operation.

  7. FAQ Section

  Q: Are these washers/shims magnetic?
  A: No. Our 304 Stainless Steel shims are generally non-magnetic in the annealed condition, making them suitable for applications where magnetism is a concern.

  Q: Can I stack multiple thin shims to achieve a specific thickness?
  A: Yes, stacking is a common and effective practice to fine-tune adjustments. For example, you can stack five 0.1mm shims to create a 0.5mm adjustment.

  Q: What is the difference between a shim and a standard washer?
  A: While they may look similar, a shim is designed for precise gap-filling and adjustment (like for bearings), often with very specific thickness tolerances. A standard washer is primarily for load distribution under a nut or bolt head.

  Q: Do you offer custom sizes?
  A: Yes, we offer laser-cutting services for custom sizes and large quantities. Please contact our sales team for a quote.
