ESZ Type 200

Product catalog summary
General Information and Product Description
The ESZ Type 200 is an unreinforced elastomeric bearing with a load capacity of up to 28 N/mm², approved under national technical approval Z-16.52-408. It is designed for static component bearing in structures such as steelworks, wood constructions, and precast concrete. The product is maintenance-free, durable, and exhibits low creep behavior. It is available in nominal thicknesses of 10, 15, and 20 mm and can be used in both indoor and outdoor environments within a temperature range of -25°C to +50°C, with short-term exposure up to +70°C.
Deformation Behaviour
The document details the compression characteristic and bulging behavior of the ESZ Type 200. Compression characteristic curves and bulging behavior diagrams are provided for various bearing formats. The deflection is influenced by the compressive stress and the roughness of the contact surfaces, with typical roughness values for concrete and steel provided.
Planning Tools and Design Tables
Design tables are included for different thicknesses (10 mm, 15 mm, and 20 mm), showing maximum permissible load-bearing capacities and rotational capacities. The tables serve as a guide, and users are advised to use the ESZ dimensioning tool for specific applications. The interaction between compressive stress and rotation is noted as not being practically accounted for in the tables.
Installation and Usage
Installation instructions emphasize the need for users to verify the suitability of the bearings for their specific applications. The document states that technical changes may occur due to new findings or product developments, and users should refer to the company's General Terms and Conditions of Sale.
Specifications
The document provides specifications for ESZ type 200 elastomeric bearings, which are used for static component bearings. The bearings have a thickness ranging from 10 to 20 mm, with a maximum permissible compressive stress of 28 N/mm². The dimensions of the bearings and permissible boreholes are outlined, with specific conditions for rectangular, strip-shaped, and round bearings.
Design Considerations
The design table included in the document shows the maximum permissible values of load-bearing capacity and rotational capacity parallel to side b (a). It is noted that the interaction between compressive stress and rotation is not practically accounted for. The shape factor changes when holes are drilled in the bearing, affecting the design basis.
Procedures
For specific dimensioning, users are advised to use the ESZ dimensioning tool online. The document also outlines the process for calculating load-bearing capacity and considering the angle of rotation, including surcharges for angular torsion.
Standards and Approvals
The bearings have national technical approval Z-16.32-408. The document emphasizes the need for proof of usability and compliance with approval conditions.
Recommendations
It is recommended to consider the effects of compressive stress and rotation when designing elastomeric bearings. The document advises against using elastomeric bearings to absorb constant external shear forces.
Key Data from Tables
The tables provide detailed values for load-bearing capacities and rotational capacities for various dimensions and configurations of the bearings. The tables also specify the maximum permissible values for different shape factors and dimensions.

Specifications and Design Considerations
The document outlines the design specifications for the ESZ type 200 elastomeric bearing, focusing on load-bearing capacity and support torsion. It includes formulas for calculating the load-bearing capacity for both rectangular and round bearings, considering geometric imperfections and deviations from plane parallelism. The document emphasizes the importance of recognizing these imperfections with a minimum of 0.01 rad and adjusting calculations accordingly.
Transverse Tensile Forces
The ESZ type 200 bearing is described as incompressible, leading to transverse expansion under compressive load. This expansion can cause shear stresses and tensile stresses in adjacent materials, potentially leading to damage. The document provides calculation methods for transverse tensile forces, comparing the "old" DIN 4141-Part 15 method with the DIBt approval method, and recommends using the less favorable calculation for reinforcement design.
Load Capacity Under Rotation
Calculations for load capacity under rotation are provided, with specific formulas and character meanings explained. The document includes tables for determining the design value of load-bearing capacity based on shape factors and aspect ratios.
Installation Instructions
Installation guidelines emphasize the need for clean, debris-free bearing surfaces, proper alignment, and adherence to technical specifications. The document advises against stacking storage units and highlights the importance of ensuring that lateral surfaces are not hindered in their planned deformation. It also stresses the need for proper joint separation and the careful production of bed joints in in-situ concrete applications.
