Industrial Disc Springs (Belleville washer) for Dynamic and Static Loads According to GOST-3057-90 or DIN2093

Production Capabilities:

Thanks to the use of modern CNC equipment and strong engineering and design base, we ensure manufacturing accuracy up to 0.01 mm at any production volume.

Characteristics for Static and Dynamic Loads

As an experienced manufacturer of disc springs, we offer products for various types of loads. Under dynamic load, the cup height should be less than 0.75 h0, which ensures optimal operational characteristics.

Design Features:

• Special profile for loss minimization
• Optimized geometry for various loads
• Possibility of combining springs in various ways
• Progressive load characteristic

Spring characteristics depend on the ratio of height to material thickness (h0/t).

Group Classification

Custom disc springs are manufactured in three main groups:

Group Parameters:

• Group 1: thickness up to 1.25 mm, ground surfaces
• Group 2: thickness 1.25 – 6.0 mm, standard execution
• Group 3: thickness from 6.0 mm, ground supporting surfaces

All dimensions are controlled according to international accuracy standards.

Technical Parameters and Tolerances

Each disc spring is manufactured with precise dimensions:

Main Parameters:

• De (outer diameter): from 16 to >250 mm
• Di (inner diameter) – according to drawing
• h0 (cup height) – according to calculation
• t (material thickness) – according to group

Diameter Tolerances:

• Up to 16 mm: ±0.2 mm
• 16-20 mm: ±0.3 mm
• 20-26 mm: ±0.4 mm
• 250 mm: ±2.0 mm

Force Characteristics

The opportunity to buy disc springs wholesale comes with complete information about force parameters:

Force Characteristics:

• F1: 25% of nominal load
• F2: 50% of nominal load
• F3: 75% of nominal load
• F: maximum calculated load

Spring deformation is controlled at all stages of loading.

Materials and Heat Treatment

Disc springs production is carried out using high-quality materials:

Steel grades:

60S2A, 65, 56SiCr, 60Si7, 50CrV4, 1.5092

Heat treatment is performed according to optimal regimes for each steel grade.

Progressive Characteristics and Combinations

We offer various assembly options for disc springs to achieve the required load characteristics:

Assembly Options:

• Parallel – increased force with the same stroke
• Sequential – increased stroke with the same force
• Combined – achieving progressive characteristic

When combining springs of different thicknesses, various progressive characteristics can be achieved.
