Technical Specifications of Spring Sustainers (TM/TV Series)

This document provides detailed technical data for the TM and TV series of spring sustainers, including dimensions, compression characteristics, stiffness constants, and load-deflection parameters.

1. Product Identification and Dimensions

The TM series sustainers are identified by model numbers ranging from TM 25 to TM 550, while the TV series includes models TV 10 to TV 40. Each model has specified dimensions given in millimeters (mm):

• B, F, H: Base dimensions (mm)
• ØA, ØD, ØC: Diameter measurements (mm)

For TM models, dimensions are consistent within two groups: TM 25 to TM 125 share dimensions 75x55x100 mm with diameters 12, 30, and 11 mm respectively; TM 150 to TM 550 have larger dimensions 120x75x155 mm with diameters 16, 30, and 14 mm respectively. TV models have fewer dimension details but specify deflection and load.

2. Compression and Stiffness Characteristics

The compression deflection (deflection under load) and stiffness constants are provided for each model:

• Deflection (Flecha): Specified in millimeters with tolerances (e.g., 24±3.0 mm for TM 25 to TM 125, 35±4.0 mm for TM 150 to TM 550).
• Stiffness (kg/cm): Indicates the load per unit deflection, increasing with model size (e.g., 10.42 kg/cm for TM 25 up to 157.14 kg/cm for TM 550).

3. Load Capacity

Load values are given in kilograms (kg) corresponding to the maximum compression each model can sustain, ranging from 11 kg for TM 25 up to 550 kg for TM 550. TV models have loads from 10 kg to 40 kg.

5. Recommendations and Usage Notes

• Selection of the appropriate sustainer model should consider the required load capacity and allowable deflection.
• Stiffness constants provide guidance on the expected resistance to compression per unit deflection.
• Dimensional compatibility must be verified to ensure proper fit in the intended application.

Overall, this technical data supports engineers and designers in selecting the correct spring sustainer model based on mechanical load requirements and spatial constraints.
