Split Spring Washer For Railway , Anti Loose Split Ring Washer With Square Ends

DIN 127 Stainless Steel Spring lock washers with square ends

1.Product Description

Spring washers are specifically designed to provide a compensating spring force and sustain a load or absorb a shock. Many design variations have evolved to best serve one or the other of these two basic functions or to optimize both functions in a single part within specific I.D./O.D. limits.

Two principle factors are at work that continually increase the requirement for spring washers:

The continuing effort to down-size many end products, relative to both weight and cost, creates a need for small, multi-functioning assembly components, such as washers that support a load, span a hole, or both, while providing a compensating spring force.
Automated assembly requires some “play” or tolerance in the “fit” of components. Spring tension is needed to compensate for these tolerances.
Recognizing these two broad areas of influence, it can be stated that the more common applications for spring washers are:

To take up “play” in assemblies due to cumulative commercial tolerances.
To compensate for small dimensional changes in assembled components.
To eliminate end play or rattles.
To maintain fastener tension or “tightness.”
To compensate for expansion and contraction or cold flow of material.
To absorb intermittent shock loads and function as working springs capable of providing controlled reaction under dynamic loads.

3.Application 

• Telecommunication sector
• Construction industry
• Steel plants
• Bridges
• Engineering
• Railway
• Power sector
• Petroleum sector   

4.Advantage 

1, Spring washer role is to tighten the nut after a stretch spring washer nut, nut against so easy to fall off. The basic action of the spring, then tighten the nut after nut a force, increasing the friction between the nut and bolt.
2, Ggenerally do not use elastic pad flat pad, (except to protect fasteners and mounting surface with a flat surface when considering pad and spring washers).
