Spring elements
This document provides comprehensive information on various types of spring elements, including system springs, helical compression springs, elastomer springs, and thrust pieces. It covers specifications, technical features, and applications in different industrial contexts.
STEINEL system springs are available in eight load types, identified by color markings. Made from alloyed valve spring steel, they are heat-treated, shot-blasted, set, and powder-coated, suitable for applications up to 180°C with forces up to 4500 daN. Specifications include pin and sleeve diameters, spring forces, and stroke lengths.
These units include all components for pre-loaded system spring units, ensuring a coordinated, ready-to-install combination for use in tools and machinery.
Made from rubber or plastic, elastomer springs offer high operational safety and longevity, used in medium and industrial tool making as cushioning and support. Guide pins prevent lateral buckling, and springs can be stacked with metallic discs.
Constructed from high-quality chloroprene elastomer (CR), these springs have a hardness of 70 ±3 Shore-A, providing high elasticity and oil resistance. Force path diagrams are provided for various diameters.
With a hardness of 90 ±5 Shore-A, these springs resist chemical and mechanical influences, offering greater spring force than rubber springs. Available in round, rectangular, or plate forms, they can be mechanically reworked.
Detailed tables include specifications for various spring models, such as dimensions, spring rates, and force capacities, essential for selecting the appropriate spring for specific applications.
The document details specifications and data for system springs like SZ8020, SZ8030, SZ8040, and SZ8045, used in nitrogen systems, tapping units, module systems, machine elements, and accessories.
- SZ8020 System Spring: Designed for heavy loads, available in various sizes with key parameters like spring rate, maximum stroke, and force at different compression levels.
- SZ8030 System Spring: Red-colored, made from profiled valve spring steel wire (52SiCrNi5), designed for long life and heavy loads.
- SZ8040 System Spring: Yellow-colored, for very heavy loads, sharing material and design characteristics with SZ8030 but for higher load capacities.
- SZ8045 System Spring: For extra heavy loads, though detailed specifications are not provided.
- All springs are made from profiled valve spring steel wire (52SiCrNi5).
- They are helical compression springs with a rectangular wire cross-section.
- Springs are set, closed, and ground to a rectangular shape for durability and performance.
- Metrics include sleeve diameter, pin diameter, wire length, spring rate, and force at specific compression percentages, crucial for selecting the appropriate spring for specific engineering applications.
The document is labeled as Version 08.2019, indicating the specifications are up-to-date as of August 2019.
Details on system springs made from profiled valve spring steel wire (52SiCrNi5) and spring steel wire in accordance with EN 10270-1 DH (type D), categorized by load capacity and identification color.
Key parameters include spring rate (N/mm), maximum stroke, and maximum force (Fmax), varying based on dimensions and load capacity.
Emphasizes adherence to DIN EN 13906 for design considerations, especially regarding preload and maximum permissible stroke.
Describes system spring units with components like adapting discs, spacer pipes, threaded discs, regrinding discs, clamping discs, and socket-head screws, available in various configurations.
Polyurethane elastomer (PUR) with a hardness of 90 ±5 Shore A, allowing a permissible deflection of up to 30%, thermally stable between -20° to +80°, and resistant to oil, grease, alcohol, benzene, and ozone.
Lists dimensions and item numbers for products like SZ5391, SZ8460, SZ8135, SZ8140, SZ8145, SZ8146, SZ8131, and SZ8130, with specific measurements and packaging details.
For products like SZ8140 and SZ8145, installation and disassembly require a suitable key, with colored thread marking for securing the thread.
Thrust pieces have varying compressive forces and spring forces, with initial and final pressure values provided for each item.
Some thrust pieces include hardened bolts or balls, enhancing durability and performance, with detailed specifications for proper selection and application.

Spring elements Elastomer springs Elastomer springs made from rubber or plastic are distinguished by their high operational safety and long life times. The preferred application fields are medium and industrial tool making, where they serve as cushioning for scrapers and wedgetype gate valves, as well as supports for tool upper parts. Elastomer springs must be guided with the aid of guide pins. These determine the position of the springs and prevent lateral buckling. Elastomer springs can also be used as individual springs as well as stacked spring units. When stacking, guide pins and metallic...

Spring elements Elastomer springs Elastomer springs This material is a high-quality polyurethane elastomer (PUR) with a hardness value of 90 ±5 Shore-A. It is distinguished by its imperviousness to chemical and mechanical influences. At the same sizes, elastomer springs have a greater spring force than rubber springs. They are ideally suitable for use wherever high forces are required for small dimensions. Force path diagrams for elastomer springs Da 20 Da 16 In addition to their usual round design, elastomer springs are also available as rectangular rods or plate material. Mechanical reworking...
