Washers We Manufacture

Complete range of precision washers for fastening, load distribution, and axial management.

Flat Washers

Plain round washers for distributing load under bolt heads or nuts.

Lock Washers

Toothed or split washers that prevent loosening due to vibration.

Spring Washers

Conical (Belleville-style) washers that provide spring action.

Belleville Washers

Stacked disc springs for compact axial load and force generation.

Wave Washers

Sinusoidal profile washers that absorb load in compact spaces.

Thrust Washers

High-load axial washers for bearing assemblies and mechanisms.

Shim Washers

Precision thickness for spacing, alignment, or tolerance adjustment.

Custom Profile Washers

Tapered, beveled, or multi-diameter custom geometry.

Washer FAQs

What washer types can you manufacture?

We manufacture all standard washer types: flat washers (plain), lock washers (toothed or split), spring washers (conical or wave), Belleville washers (stacked disc springs), wave washers (sinusoidal profile), thrust washers (for axial loads), shim washers (for spacing/alignment), and custom profile washers. Specify the washer type and application on your drawing.

What materials are best for high-load washers?

Steel 4140 (hardened) is the standard for high-load applications due to excellent spring properties and strength. Stainless steel 17-4 PH offers high load capacity plus corrosion resistance for marine applications. Bronze is used for thrust washers in bearings where soft-on-steel is required. Spring steel is ideal for lock and spring washers. Choose based on load, environment, and temperature.

What tolerances can you hold on washer thickness?

Standard CNC machining holds ±0.05mm on washer thickness. For tightly stacked washers or precision shim applications, we hold ±0.02mm. Spring washers (Belleville, wave) maintain thickness within ±0.02mm. Specify your tolerance and we will achieve it.

What is the typical lead time for custom washers?

Lead time for custom washers is 3–7 business days for prototypes and small volumes. Flat washers and simple profiles: 3–5 days. Spring washers and complex profiles: 5–7 days. High-volume orders (100+) benefit from stamping or progressive die tooling with longer planning windows. Request a quote with your timeline.

Can you manufacture washers with custom OD/ID ratios?

Yes. Custom outer diameter (OD) to inner diameter (ID) ratios are standard. We machine washers for any ID from 1mm to 100mm, with OD and thickness specified on your drawing. Custom profiles including tapered edges, bevels, or multi-diameter washers are also available.

Do you offer surface finishing for washers?

Yes. Surface finishing includes passivation (stainless steel), zinc plating (steel), nickel plating, or black oxide finish. Bead-blasting can provide a matte appearance. Specify your finish requirement on your quote request, and we will arrange finishing through our partners.
