New Technologies and Enhancements Research and Development New Products and Services
NEW Technology
Enidine engineers continue to monitor and influence trends in the motion control industry, allowing us to remain at the forefront of new energy absorption and vibration isolation product development. Our experienced engineering team has designed custom solutions for a wide variety of challenging applications, including automated warehousing systems and shock absorbers for hostile industrial environments such as glass manufacturing, among others. These custom application solutions have proven to be critical to our customers’ success. Let Enidine engineers do the same for you.
A talented engineering staff works to design and maintain the most efficient energy absorption product lines available today, using the latest engineering tools:
• Solid Modeling • 3-D CAD Drawings • 3-D Soluble Support Technology • Finite Element Analysis • Complete Product Verification Testing Facility New product designs get to market fast because they can be fully developed in virtual environments before a prototype is ever built. This saves time and lets us optimize the best solution using real performance criteria.
Custom designs are not an exception at Enidine, they are an integral part of our business. Should your requirements fit outside of our standard product range, Enidine engineers can assist in developing special finishes, components, hybrid technologies and new designs to ensure a “best-fit” product solution customized to your exact specifications.

Jarret Series
Overview
LR Series
BC5 Series
BC1GN Series
BC1ZN Series
Spring
The design of Jarret Series Industrial Shock Absorber utilizes the unique compression and shear characteristics of specially formulated silicone elastomers. These characteristics allow the energy absorption and return spring functions to be combined into a single unit without the need for an additional gas or mechanical spring stroke return mechanism.
Applications Shock protection for all types of industries including: Defense, Automotive, Railroad, Materials Handling, Marine, Pulp/Paper, Metal Production and Processing.

Visco-elastic technology makes use of the fundamental properties of specially formulated Jarret visco-elastic medium.
Compressibility: Preloaded spring function F = F0 + Kx
Viscosity: Shock absorber function F = F0 + Kx + CV α with α between 0,1 and 0,4 The two functions can be used separately or in combination, in the same product: Preloaded Spring: Spring Function Only • Hysteresis of between 5% and 10% • Reduced weight and space requirement • Force/stroke characteristic is independent of actuation speed Shock Absorber Without Spring Return: Shock Absorbing Function Only • Dampening devices • Blocking devices

Email: industrialsales@enidine.com
Preloaded Spring Shock Absorbers: Combine Spring and Shock Absorber Functions • Dissipate between 30% and 100% of energy • Force/stroke characteristics remain relatively unchanged between 15°F and 160°F (-10°C and + 70°C) * Spring and shock absorber products are capable of functioning between 15°F and 160°F (-10°C and + 70°C). However, standard products are not intended for use over the full rated temperature range. Consult factory for special product considerations required to accommodate operation over a wide temperature range.
