High Carbon Steel Belleville Spring Washers – ASR 0.38″ ID x 0.95″ OD

Description

Product Overview

Our High Carbon Steel Belleville Spring Washers are precision‑engineered components designed to meet the rigorous demands of modern industrial fastening systems. Constructed from ASTM‑A684 certified 1074 high carbon steel, each washer delivers a maximum load capacity of 261 foot‑pounds while maintaining a compact profile of 0.38 inches inner diameter and 0.95 inches outer diameter. The dry‑to‑the‑touch oil finish not only enhances corrosion resistance but also provides a smooth, low‑friction surface that reduces wear during repeated compression cycles. With a free height of 0.07 inches and a compressed height of 0.058 inches, these washers offer consistent spring action, ensuring reliable torque retention across a wide range of applications. Their magnetic properties aid in handling and installation, while the ability to maintain loads over time makes them a trusted choice for high‑stress environments. Designed for non‑corrosive settings, they perform flawlessly up to 350 °F (180 °C), delivering durability where other components might fail.

Usage

These Belleville washers excel in a variety of industrial scenarios, from heavy‑duty machinery assembly to precision equipment maintenance. They are ideal for bolted joints that require a constant preload, such as gearboxes, pumps, and high‑speed rotating equipment. The compact dimensions allow them to fit into tight spaces, making them suitable for aerospace and automotive applications where weight and size constraints are critical. Their high temperature tolerance enables use in environments like furnace doors, heat exchangers, and chemical processing equipment where temperatures regularly approach 350 °F. Additionally, the magnetic characteristic simplifies inventory management and field installation, especially in settings where quick part identification is essential. Whether you are securing a structural steel frame, calibrating a vibration isolation system, or reinforcing a high‑stress connection, these washers provide the consistent performance needed to keep your projects running smoothly.

FAQ

What is the maximum load these washers can handle?

The washers are rated for a maximum load of 261 foot‑pounds, making them suitable for high‑stress fastening applications where reliable preload is essential.

Can these washers be used in high‑temperature environments?

Yes, they are designed to operate safely up to 350 °F (180 °C), which covers most industrial heating processes and equipment that generate elevated temperatures.

Are the washers magnetic, and does that affect their performance?

The high carbon steel material is highly magnetic, which aids in handling and inventory management. The magnetic property does not interfere with the washer’s spring action or load‑bearing capabilities.

What finish is applied to the washers, and why is it important?

They feature a dry‑to‑the‑touch oil finish that enhances corrosion resistance and reduces friction during compression, extending the life of both the washer and the mating components.

How do I determine the correct torque for installation?

We recommend consulting the manufacturer’s torque tables for the specific bolt grade you are using. As a general guideline, the washer’s preload can be achieved by applying a torque that compresses the washer to its specified compressed height of 0.058 inches.
