What are wavy washers for?
Wavy spring washers are utilized to accommodate discrepancies with types of commercial equipment. In addition, wave washers are designed to eliminate the effects of misalignment issues, such as excess vibration and motion. Technicians and contractors use wavy washers to increase the lifespan of ball bearings.
How are wave washers measured?
To Measure the Free Height of a Wave Spring:
Lower the top measuring surface until it touches the spring. Apply a slight force to deflect the spring until the crests of all waves come in contact with the loading surfaces (top & bottom) The distance between the two parallel plates is the free height.
How do wave washers work?
Wave washers, also commonly referred to as wave springs or coiled wave springs, are used to absorb stress due to axial compressive loads, acting as a cushion. The waves of the wave washer provide 3, 4, or 6-point contact that results in greater load‑bearing capacity and a medium range of deflection.
Where does the wave washer go?
For GXP cranks (22mm/24mm), the spindle spacers and/or wave washer will always be positioned between the drive side seal and the crank arm. In most installs, there will be a gap between the right crank arm and the drive side seal.
What is a wavy washer called?
Wave washers, also referred to as wave springs, are wavy metal washers designed to provide a compensating spring force or absorb shock when under load. Many design variations have evolved to best serve these basic functions.
What can be used instead of a lock washer?
An alternative to using a lock or vibration-resistant washer is to use thread-locker or a lock nut. Lock nuts may either use friction, such as a nyloc, distorted thread or jam nut, or they may use positive locking, such as a castellated or slotted nut.
Is standard for wave washer?
Wave washers, also called spring washers, feature a lobed design suitable for low strength fastening, irregular surfaces, and variations in tolerance.

How do you use a spring washer?
When used correctly, a spring washer will hold the nut or other threaded fastener in place. To help it accomplish this, put the spring washer on first, below the fastener. Ensure that the washer is flush against the fastener and the other surface to create a tight connection.
Are lock washers worth it?
The body of evidence, based upon both experience and experimental results, is that they do not prevent loosening and can be shown to actually speed up the rate of loosening in many cases. Junker originally showed in his work published in 1969 that these washers are ineffective in preventing loosening.
What type of lock washer is best?
Helical spring lock washers are the most common form of lock washer and are best suited to applications with smaller loads. High-collar lock washers are a kind of split washer. Internal use lock washers have teeth made to bite into the nut/screw head and surface it contacts.
When should you use a wavy washing machine?
Wavy washers offer a accurate solution for situations where space is limited or when small deflections are required, and are designed to provide a compensating spring force or absorb shock when under load.
Do I need wave washer GXP?
You need the wavy washer on the GXP cranks as well. The reason for this is that the non drive side bearing is 22mm internal diameter and it buts up against a step in the crank axle. When the system is tightened up the drive side bearing is free floating while the non drive side is captive.
What are the 4 types of washers?
Following are the types of washers, as per their utility and functions:
- Split lock washer.
- External tooth lock washer.
- Internal tooth lock washer.
What is the difference between form A and form B washers?
Type A is a series of steel washers at broad tolerances, where precision is not critical. Type B is a series of flat washers with tighter tolerances where outside diameters are categorized as “narrow”, “regular” or “wide” for specific bolt sizes. “Type” is not to be confused with “form” (but often is).
Which is better lock nut or lock washer?
Here is the basic breakdown of when you will want to use a locknut over a lock washer: When you need something that can handle the pressure that comes with torquing down a bolt or screw, choose a lock washer.
What is importance of compensating washer?
Compensating the parallelism when it is in fault, achieving that the pressure of tightening does not fall on a single point damaging the material. As spacers for the parts used. As springs between the pieces. Preventing galvanic corrosion through insulation of metal screws from aluminum surfaces.
What is the difference between a wave washer and a spring washer?
Wave and split washers generally bottom out at such low forces that they provide very little vibration resistance. Belleville washers, conical spring washers or cupped spring washers, these are disc-shaped washers that have been pressed into a conical shell to create a very compact spring.
Are spring washers good?
When should you not use a lock washer?
When Not to Use Nord-Lock Washer? | Q&A – YouTube
Do you need a wavy washer?
The wavy washer sets the bearing preload for cranks that don’t have a preload adjuster. Since this is an adapter, there is no adjuster, so you should use a wavy washer. Preload play is in the tens of thousands of an inch. Setting it properly is key to BB30 bearing life.
What are the strongest washers?
Washer Materials and Types
Carbon steel is stronger than stainless steel, but stainless steel will not rust or corrode like carbon steel can. Other metal washers include zinc, copper, brass and iron. You can also find specialty washers, such as plastic washers, rubber washers, ceramic washers and phenolic washers.
What are Form G washers?
Form G washers are the heaviest duty flat round washers available as standard. They are much thicker than regular washers with a much bigger outside diameter. Available in sizes M5 to M30 in zinc plated and stainless steel.
Do you torque bolts with lock washers?
How Lock Washers Work. Lock washers are designed to be tightened to a required torque beneath an ordinary fastener. They exert a spring tension that keeps the fastener from vibrating loose. They are often attached to the nut side of the fastener.
Does the lock washer go on first?
When used correctly, a lock washer will hold the nut or other threaded fastener in place. To help it accomplish this, put the lock washer on first, below the fastener. If your project calls for other washers or hardware elements, they should go on before the lock washer so that it can hold them in place.
Are there different grades of washers?
Grades: Flat washers do not have a specific grade as traditional fasteners such as Grade 5 or Grade 8 bolts do however there are two common types of steel used. Standard steel flat washers (low carbon steel) are not rated for hardness. Hardened steel flat washers.
