Circlips are made from carbon spring steel strips or bars serve as radial spring fasteners for positioning and retaining components in assembly. Normally, the circlips are either axially assembled (either over shafts or inside bores) or radially assembled over shafts.

Serrated lock washers are primarily intended to establish electric contact in cases where the screwed parts are coated with non conducting lacquer and similar coatings. If such washers together with bolts and nuts of low property classes are used to prevent unscrewing, then the suitability for this purpose shall be proved in each case.

Belleville spring washers type ‘A’ can be used in most light metal assemblies to provide a useful elastic spring action proportionately high with respect to the washer’s outer diameter. They can be flattened out completely when tightened, with out effect on their elasticity. Also used in certain assemblies with out effect on their elasticity. Also used in certain assemblies with a view to compensating any axial play.

Belleville spring washers type ‘B’can be used with all grades of materials of bolts or screws, as well as the torques applied therewith.

Specially recommended in the following cases

On aluminium, light alloy or plastic work pieces, on painted or polished parts with a view to avoiding deterioration of the surfaces.With light alloy screws (Aluminium, berillium, copper, brass.

For locking bolts, screws and nuts.

To be used particularly in cases where fasteners serve to lock parts likely to be subjected to extreme vibrations or serve shocks.

They are noted for:
A high-flattening load in keeping with grade of bolts or screws used
Ahigh elasticity or spring return to compensate any play due to
Setting of material under tightening pressure wear and tear
Compression of intermediary elements (gaskets, plastic rings)
Differential expansion of parts due to the material they are made of (steel,
    copper, aluminuim, alloys).

 

Replaces different fasteners
Replacing a dowel pin
Replacing a keys
Replacing a Rivet Shaft
Replacing a Copper Pin
Replacing a Set Screws
Replacing a Head Pin
Replacing a HUB on a Gear
Replacing a bolt nut
Replacing a rivet

To be used mainly for compensating of play or as a spring in certain assemblies. Elimination of ratting, reduction of noises, maintenance of a determined pressure etc.

Their spring action is unlimited, although the flattening load can be high.

In order to obtain a more important spring action under relatively slight flattening load, it is sufficient to stack them in opposition.

In order to obtain a stronger spring action with a low flattening load, it is sufficient to stack them in series.

Multitooth lock washers are used with screws and nuts to effectively add spring take up to the screw elongation and to increase the frictional resistance under the screw head or nut face. These are normally used where security of assembly is critical.
