Metric Belleville Spring Washer 28mm OD 0.402″ ID 1853N Load 10 pcs

Description

Product Overview

The Metric Belleville Spring Washer is engineered to meet the rigorous demands of modern industrial and scientific environments. Featuring a 28mm (1.102″) outer diameter, a 0.402″ (10.2mm) inner diameter, and a precise 0.049″ (1.3mm) thickness, this conical spring washer delivers an impressive maximum load of 1,853 N. Manufactured in accordance with DIN2093 standards, the washer offers a consistent, repeatable spring force that maintains tension over a wide range of temperatures and vibration conditions. The disc‑spring geometry provides a compact profile while delivering high axial load capacity, making it an ideal choice for applications where space is limited but performance cannot be compromised. Each pack contains ten washers, ensuring you have sufficient inventory for batch production, routine maintenance, or emergency repairs. The washers are produced by a Disc and Belleville Approved Manufacturer, guaranteeing adherence to strict quality controls and traceability throughout the supply chain.

Usage

These Belleville spring washers excel in a variety of demanding settings. In heavy‑duty machinery, they are used to preload bolts, preventing loosening caused by thermal expansion, vibration, or cyclic loading. Automotive manufacturers rely on them for engine assemblies, transmission housings, and suspension components where reliable torque retention is critical. In the aerospace sector, the washers provide the necessary resilience for wing‑root fittings, landing‑gear brackets, and control‑surface linkages, where weight savings and high‑strength performance are paramount. The compact conical shape also makes them suitable for electronic enclosures, where they absorb shock and maintain connector integrity. Maintenance technicians appreciate the ease of installation—simply place the washer between the bolt head and the mating surface, and the built‑in spring force does the rest. Because the washers are supplied in a convenient pack of ten, they are ready for both one‑off repairs and large‑scale production runs.

FAQ

What is the correct torque setting when using this Belleville washer?

The appropriate torque depends on the bolt grade, thread size, and the desired preload. As a general guideline, multiply the bolt’s nominal torque by a factor of 0.8 to 1.0 to account for the washer’s spring effect. For precise applications, consult the manufacturer’s torque chart or perform a calibrated preload test.

Can these washers be used with stainless steel bolts?

Yes, the Metric Belleville Spring Washer is compatible with stainless steel fasteners. However, because stainless steel has a lower modulus of elasticity than carbon steel, you may need to adjust the torque slightly to achieve the same preload. Always verify the final assembly with a torque wrench and, if possible, a load cell.

Are the washers suitable for high‑temperature environments?

These washers are made from heat‑treated alloy steel that retains its spring characteristics up to approximately 250 °C (482 °F). For applications exceeding this temperature, consider a specialty high‑temperature alloy or consult our engineering team for a custom solution.

How do I store the washers to maintain their performance?

Store the washers in a dry, clean environment away from direct sunlight and corrosive chemicals. Keeping them in their original packaging until use helps protect the surfaces from contamination and preserves the calibrated spring force.

What is the warranty coverage for these washers?

We offer a one‑year limited warranty covering material defects and manufacturing errors. If a washer fails under normal operating conditions within the warranty period, we will replace it at no cost, provided the failure is not due to misuse, over‑torquing, or improper installation.
