Metric Steel Belleville Washer 40mm OD x 14.3mm ID, 2550N Load (10

Description

Product Overview

The Metric Steel Belleville Washer is engineered to meet demanding industrial applications where reliable tension and load-bearing capacity are essential. With a precise outer diameter of 40mm and an inner diameter of 14.3mm, this conical spring washer fits standard metric fasteners and provides a consistent preload across a wide range of bolt sizes. The washer’s thickness of 1.5mm, combined with a maximum load rating of 2,550 Newtons, ensures that it can sustain heavy-duty forces without permanent deformation.

Manufactured from high‑grade carbon steel, each washer undergoes a rigorous heat‑treatment process that enhances hardness and resistance to wear. The material choice delivers excellent fatigue life, making the washers suitable for repetitive assembly and disassembly cycles common in machinery maintenance. The product complies with DIN2093 specifications, guaranteeing dimensional accuracy and interchangeability with other industry‑standard components.

Packaged in sets of ten, the washers are ready for immediate deployment in production lines, repair workshops, or field service kits. The compact packaging reduces storage space while protecting each washer from corrosion and physical damage during transit. The product model DS‑401415, first released on November 10, 2015, has earned a solid reputation among engineers and procurement specialists for its dependable performance and cost‑effective pricing.

Usage

These Belleville spring washers excel in applications that demand a reliable, repeatable clamping force. Typical use cases include securing heavy equipment frames, automotive suspension components, and high‑vibration machinery where maintaining torque is critical. The conical shape of the washer converts axial load into a uniform radial pressure, preventing loosening caused by dynamic loads or thermal expansion.

Installation is straightforward: the washer is placed between the bolt head and the mating surface, then tightened to the specified torque. The spring action of the washer compensates for minor variations in bolt length and surface irregularities, delivering a consistent preload that enhances joint integrity. Because the washer distributes load over a larger area, it reduces the risk of surface indentation or damage on delicate components.

In environments with extreme temperature fluctuations, the steel composition retains its elasticity, ensuring that the preload does not diminish over time. This makes the washers ideal for aerospace, marine, and heavy‑industrial settings where reliability under harsh conditions is non‑negotiable. Additionally, the washers are compatible with lubricants and anti‑seize compounds, further extending their service life.

When used in assemblies that require periodic maintenance, the washers can be easily removed and re‑installed without loss of performance, simplifying routine inspections and part replacements. Their standardized dimensions also allow for seamless integration into existing inventory systems, reducing the need for multiple part numbers and simplifying procurement processes.

FAQ

What size bolt threads are compatible with this Belleville washer?

The washer is designed for metric bolt sizes that accommodate a 14.3 mm inner diameter, typically ranging from M12 to M24. It works well with standard coarse and fine thread profiles, providing a reliable preload across the specified range.

Can these washers be used in high‑temperature environments?

Yes. The carbon steel material retains its elasticity up to temperatures of approximately 250 °C (482 °F). For applications exceeding this range, a heat‑treated variant or a stainless‑steel alternative is recommended to maintain performance.

How do I determine the correct torque setting when using these washers?

Torque values depend on the bolt diameter, material, and the desired preload. As a general guideline, multiply the bolt’s nominal tensile strength by a factor of 0.2 to 0.3 and adjust for the washer’s spring rate. Detailed torque tables are available in our technical datasheet, which can be requested from our support team.

Are the washers coated for corrosion resistance?

The standard version is supplied in untreated carbon steel. For applications requiring enhanced corrosion protection, we offer zinc‑plated or hot‑dip galvanized options that provide additional resistance to moisture and chemicals.

What is the lead time for ordering a pack of ten?

In‑stock inventory typically ships within 2‑3 business days. For larger orders or custom specifications, a standard lead time of 7‑10 business days applies, with expedited shipping available upon request.
