2007 EFDYN Catalog
2007 EFDYN Catalog
This section outlines formulas for calculating various types of energy, including kinetic energy (EK), propelling force energy (EP), energy per cycle (EC), and energy per hour (EH). It provides examples for different applications such as horizontal, vertical, inclined, and rotary, and guides on selecting the appropriate shock absorber model based on these calculations.
The worksheet is designed to collect essential data for selecting the ideal shock absorber. It includes fields for contact information, application description, direction of motion, and impact weight and velocity.
These are adjustable, self-compensating shock absorbers with strokes ranging from 0.6” to 2” and effective weights from 7.5 to 3,800 lbs. They manage energy per hour between 313,000 and 1,667,000 in-lbs.
Features strokes from 1” to 10”, bores from 1/2” to 2”, and effective weights from 10 to 396,000 lbs. Energy per hour ranges from 750,000 to 17,000,000 in-lbs.
Offers strokes from 1” to 3”, bores of 7/8” and 1 1/8”, and effective weights from 10 to 75,000 lbs. Energy per hour is between 1,475,000 and 3,600,000 in-lbs.
This series includes self-compensating, fixed orifice, and custom metering options with strokes from 2” to 72”, bores from 1 1/8” to 8” (custom), and effective weights from 15 to 2,100,000 lbs. Energy per hour ranges from 1,300,000 to 98,000,000 in-lbs.
Features strokes from 2” to 10”, bores of 1 1/8”, 2”, and 4”, with energy per hour between 2,700,000 and 38,600,000 in-lbs.
Offers strokes from 2” to 10”, bores of 1 1/8”, 2”, and 4”, with energy per hour ranging from 4,000,000 to 33,000,000 in-lbs.
This section mentions additional products related to shock absorption and motion control, though specific details are not provided.
The document provides detailed specifications and applications for various bumper models used in industrial settings. These bumpers are designed for energy management and are suitable for a range of equipment including business machines, robotics, and amusement rides.
The document lists multiple models of bumpers, categorized under GBA, GBR, and TCB series. Each model is detailed with dimensions, energy capacity, peak dynamic force, and weight. For example, the GBA-101S model has a height of 0.82 inches, a rated energy capacity of 50 in-lbs, and a peak dynamic force of 300 lbs.
The bumpers are applicable in various sectors such as business machines, pneumatically powered equipment, robotics, electronic switch gears, and fitness equipment. They are designed to meet industry standards like OSHA and CMAA.
The document also mentions other EFDYN products such as custom shocks and rotary dashpots, tailored for specific applications requiring unique engineering solutions.
For custom solutions and further inquiries, EFDYN provides a contact number for consultations and expedited services.
