Product Overview

Overview
Disc springs are springs formed by making a hole in the center of a disk to create a conical disc shape. Unlike traditional springs, they have unique functions.
Can withstand heavy loads with small deformation, has a short stroke, requires little space, is easy to use in combination, convenient for maintenance and replacement, highly economical and safe, and has a long service life.
At the same time, it is also considered a spring with a high level of design difficulty. When used in stacks, even slight dimensional differences can have a significant impact on the load, and may also cause a reversal in the relationship between displacement and load.

Product Features

Characteristics of Disc Springs
1. High stiffness, strong cushioning and vibration absorption capability, able to withstand large loads with small deformation, suitable for applications with limited axial space.
2. This type of spring has variable stiffness characteristics.
3. By using the same disc springs in different combinations, the spring characteristics can be varied over a wide range.
Can be arranged in parallel overlap, vertical combination, or a combination of parallel and vertical arrangements.

■ Differences between MISUMI Economy Series and Market Standard Products

Products circulating on the market *	MISUMI Economy series
24H Salt Spray Test Results	48H Salt Spray Test Results
Surface treatment: black oxide coating	Surface treatment: phosphating

■ Dimensional Consistency Test

Products circulating on the market *	MISUMI economy series
30PC Consistency Test (CPK)	50PC Consistency Test (CPK)
Tolerance of Spring Height (H0) CPK=0.48	Tolerance of Spring Height (H0) CPK=1.48	Product dimensional consistency is three times that of products circulating on the market
Overlapping use may cause unstable performance	Ensure stable performance when used in overlap

· When used in combination, the inner cone height and disc thickness of disc springs have a significant impact on the spring's performance characteristics. If dimensional consistency is low, the internal stress distribution across the cross-section will be uneven. A good CPK index can effectively improve its fatigue strength and the vibration absorption capacity per unit volume of material. Extend product lifespan.
*Products circulating on the market are similar products randomly purchased by our company from online or offline markets
*The test data are obtained through testing by our company, which are for reference only

Usage Method

Precautions

Changes in Inner and Outer Diameter During Compression
Disc Spring Precautions and Disc Spring Coefficient

*When the travel of the disc spring exceeds 75%, the load increases only slightly, but it greatly affects the service life of the disc spring. Therefore, the optimal operating range is between 10% and 75% of its maximum displacement.
*When using disc springs in combination, a guide rod or guide sleeve is required for the inner or outer diameter. The shape of the spring changes as it is compressed, so it is important to consider the clearance with the guide component.

Inside/Outside diameter (mm)	Recommended Clearance (mm)
15 or Less	0.2
20 or Less	0.3
26 or Less	0.4
45 or Less	0.6
75 or less	0.8
140 or Less	1.0
250 or Less	1.6

Frequently asked question (FAQ)

Question: What is the difference between a disc spring and a coil spring?: Answer: 1. Disc springs can handle large loads and can be installed in small spaces. By combining them, the spring characteristics can be varied over a wide range.
2. When subjected to a load, a large stroke can be achieved. They have load characteristics with low hysteresis and high repeatability during compression and decompression.
Question: What types of materials are used for disc springs on the market?: Answer: The standard material is 60Si2Mn, but the best material should be 50CrV4, which is equivalent to the imported 51CrV4. The rest are unconventional materials such as stainless steel.
