Carbon Steel Shim Rings DIN 988

Carbon Steel Shim Rings DIN 988

Introduction: Shim Rings

Shim Rings are essential mechanical components designed to take up excess space between machine parts, ensuring optimal alignment, spacing, and load distribution. Specifically manufactured according to DIN 988 standard, these rings are prevalent in various mechanical and automotive applications. At Flybear Fastener, we manufacture DIN 988 Shim Rings using premium-grade carbon steel, ensuring strength, durability, and precision.

With their simple yet high-performing design, Shim Rings are ideal for axial spacing in bearings, bushings, gears, and other rotating machine assemblies. These components offer cost-effective solutions for minimizing axial clearance and enhancing machinery life.

Material & Manufacturing Process

The DIN 988 Shim Rings offered by Flybear Fastener are crafted from high-grade carbon steel, chosen for its excellent hardness, wear resistance, and machinability. The manufacturing process involves precision stamping and CNC machining to achieve accurate tolerances and consistent quality.

Key steps include:

  1. Raw Material Inspection – confirming the chemical and mechanical properties of carbon steel.
  2. High-Precision Stamping – each ring is shaped with extreme accuracy to ensure seamless fitting.
  3. Heat Treatment (optional) – enhances the mechanical strength.
  4. Surface Finishing – options such as black oxide and zinc-plating to offer corrosion resistance.
  5. Final Quality Control – every piece goes through dimensional inspection and surface checks.

Typical Applications of DIN 988 Shim Rings

The usage of shim rings spans across diverse industries due to their functional versatility. Common application scenarios include:

  • Automotive gearboxes and transmission assemblies
  • Electric motor and pump systems
  • Machine tool spindles
  • Industrial reducers and bearing housings
  • Aerospace instruments
  • Robotics components & automation systems

These rings are especially crucial in ensuring precision alignment and fine-spacing in low-clearance assemblies.
