Product Description
304 Stainless Steel DIN 988 Precision Shim Washers
Our 304 Stainless Steel DIN 988 Shim Washers (also known as adjusting or support washers) are ultra-precision flat spacers designed to adjust axial clearances and eliminate play in mechanical assemblies. Manufactured strictly in accordance with DIN 988 standards using premium-grade SS304, these thin shims offer exceptional thickness tolerance and excellent corrosion resistance.

Key Features & Advantages
High-Precision Thickness Tolerance: Our DIN 988 shims undergo rigorous precision rolling and stamping processes to guarantee ultra-tight thickness tolerances, ensuring stable performance in high-RPM rotating shafts.
Premium 304 Stainless Steel: Unlike standard carbon steel shims that rust and freeze assemblies over time, our SS304 shims offer superior resistance to chemicals, moisture, and oxidation. Perfect for food processing, marine, and outdoor operations.
Flawless Flatness & Burr-Free Edges: Utilizing advanced fine-blanking technology and multi-stage tumbling, every shim washer features excellent flatness and perfectly rounded, burr-free edges to prevent localized stress concentration.
Comprehensive Thickness Stacking Options: We offer mixed-thickness assortment kits or single-size bulk packages, allowing engineers to stack multiple thin shims to achieve exact clearance compensation.
Typical Industrial Applications
- Bearing Preloading: Adjusting the distance between bearings to reduce noise and friction
- Gearbox & Transmission Systems: Setting precise backlash and gear meshing
- Pumps & Valves: Aligning impellers and sealing rings to prevent fluid leakage
