Metric Steel Belleville Spring Washer 40mm OD 20mm ID 1.5mm Thick

Description

Product Overview

The Metric Steel Belleville Spring Washer is engineered to meet the rigorous demands of modern industrial fastening systems. Constructed from high‑grade carbon steel, each washer features a precise conical shape that delivers consistent spring force across a wide range of applications. The dimensions—40 mm outer diameter, 20 mm inner diameter, and 1.5 mm thickness—are calibrated to provide a maximum load capacity of 2,616 N, making these washers suitable for heavy‑duty machinery, automotive components, and high‑stress equipment assemblies. The disc‑spring design ensures uniform pressure distribution, reducing the risk of bolt loosening caused by vibration or thermal expansion. With a pack of ten units, users receive a reliable supply that supports batch production and maintenance schedules.

Manufactured under the strict quality standards of Disc and Belleville Approved Manufacturer, each washer undergoes rigorous testing for dimensional accuracy, tensile strength, and corrosion resistance. The DIN2093 compliance guarantees compatibility with international fastener standards, while the M40‑Disc‑Spring classification highlights its suitability for metric‑based assemblies. The lightweight nature—only 0.01 ounces per washer—facilitates easy handling and installation without compromising structural integrity.

Usage

These Belleville spring washers excel in environments where vibration, shock, and cyclic loading are prevalent. Typical use cases include securing engine mounts, transmission housings, and heavy‑duty gearboxes in automotive and industrial settings. The washers also perform effectively in agricultural equipment, construction machinery, and aerospace applications where reliable torque retention is critical. Their compact size allows for integration into confined spaces, and the conical spring action compensates for minor misalignments, ensuring a tight fit even under fluctuating temperatures.

Installation is straightforward: place the washer between the bolt head and the mating surface, then torque the fastener to the specified value. The washer’s spring action will automatically adjust to maintain the desired preload, reducing the need for frequent re‑torquing. For maintenance, the washers can be inspected visually for signs of wear or corrosion and replaced without the need for specialized tools.

FAQ

What material is the washer made from?

The washer is fabricated from high‑grade carbon steel that has been heat‑treated for enhanced strength and coated to resist corrosion.

Can these washers be used with non‑metric bolts?

While the washer dimensions are metric, they can be paired with compatible imperial fasteners provided the bolt head and bore sizes match the washer’s inner and outer diameters.

How many washers are included in each pack?

Each package contains ten individual washers, allowing for multiple installations or spare parts for future maintenance.

Are the washers compliant with any industry standards?

Yes, they meet DIN2093 specifications and are classified under the M40‑Disc‑Spring category, ensuring compatibility with a wide range of industrial standards.

What is the recommended torque setting for these washers?

Torque values depend on the specific application and bolt size; however, a typical range for a M40 bolt with this washer is between 70‑90 Nm. Always refer to the equipment manufacturer’s guidelines.
