White / Yellow Zinc Split Lock Washer , Belleville Disc Spring Washer Carbon Steel

Spring washer are mainly punched out from iron plates. Spring washer: after lock, use elastic pad have the effect of locking, and of course to a double nut effect is poor.
Single nut + flat mat, play mat: rely on the nut itself locking force and elastic cushion locking performance, a double nut.
Flat washer: only increase the surface area Prevent the soft substrate was installed a damaged, or is blocking hole.
Locking method still has a lot of, this is just a very old some basic locking method, but also very practical.
Trampoline's role is to prevent the screw loose caused by the vibration of the machine or heat bilges cold shrink.Role is flat mat, increase the contact area of the screw and machine 1, 2, eliminate the trampoline at the time of discharge screw damage on the surface of the machine must be a spring when using a flat mat, flat pad close to the surface of the machine, spring cushion between the plain washers and nuts.
Flat mat role is long screw is screw is half buckles added flat washer cap can take full 2 is the place on the screw hole is too large added a flat washer not leak down
Trampoline is mainly used for locking, used in vibration is not big, if the vibration is big, generally want to use the double nut locking or other locking method, flat washer is mainly used to increase the contact area, like on the bearing seat because the drive is long and narrow hole, must be the home of the flat washer.
Flat mat increase the contact area, spring cushion is used for locking, when it is used in trampoline should pay attention to the direction of the opening, or the locking effect is not big.

The sizes of spring washer we have are from M3 to M52.

1. Internal tooth washer, external tooth washer
There are a lot of sharp, flexible thumbs on the circumference that press against the bearing surface to stop the fastener from loosening. Internal rubber washers are used under the heads of smaller head size; external rubber washers are mostly used under the head of bolts and nuts. The toothed elastic washer is smaller in size than ordinary spring washers and has even force on the fastener to prevent loosening and reliable, but should not be used in the usual disassembly place.
2. Wave spring washer
Wave washers divided into WG type, WL type, WN type

3. Disc spring washer
Disc spring washer Belleville spring washer, also known as Belleville French. HDS Series is a very effective bearing load and elastic recovery. Bolt tension can withstand slack due to wear, creep, relaxation, thermal expansion, shrinkage, or seal compression of the consumable parts. The HDS series multiples the elasticity of the screw several times, effectively replacing conventional spring washers, but not suitable for locking washers and flat washers.
