Wave washer, Crest-to-Crest Wave washers are pre-stacked in series, decreasing the spring rate proportionally to the number of turns. This will maintain the same force and load specifications of a conventional round wire washer with an additional advantage resultant lowered and compacted operating heights, free heights and solid heights.. As a replacement for helical compression springs, Crest-to-Crest springs can develop similar forces, yet occupy one-half (12) or less the axial space that allows for strict space constraints.

A wave spring is made from coiled flat wire with waves added to give it a spring effect. The on-edge-coiling process creates a circle with one or more turns to specifications in any diameter and any number of specific designed waves. When compared with typical coil springs, wave springs have equal performance with about half of the overall free height. This not only provides for space savings, but also smaller assemblies that use less materials, hence lower production costs. Wave springs are a precision spring and available in many styles and materials.

Spring Steel & Stainless Steel in 2 / 3 / 4 waves, gap type, overlap type, double wave type A wave spring is made from coiled flat wire with waves added to give it a spring effect. The on-edge-coiling process creates a circle with one or more turns to specifications in any diameter and any number of specific designed waves. When compared with typical coil springs, wave springs have equal performance with about half of the overall free height. This not only provides for space savings, but also smaller assemblies that use less materials, hence lower production costs. Wave springs are a precision spring and available in many styles and materials. Wave Washers are solid washers that have pressed waves. These items are typically used to offer preload to bearings and bolts Flat Wire Wave Springs v/s Conventional Stampings No material waste compared to stamped parts Rolled flat wire features edges with a radius—NO DAMAGE TO SHAFT/BORE No stamping burrs eliminates the grinding process No stamping through the metal grain--microstructures remain intact Microstructure offers better strength because the line of force in circumferential direction is not disturbed; risk of fatigue cracking and inconsistent loading in a lot is minimized. Applications: Quick Connectors for military, aerospace and industrial applications Centrifugal Pump Bearing Retention Fluid Power Assemblies Mechanical seals Automotive Air assemblies Sprinkler Device Inflation component Flashlight assembly

Snap rings, Retaining Rings are precision engineered components that are designed to be applied on shafts or in bores and provide a shoulder that accurately positions, locates and retains other parts of an assembly. BM, an expertise in manufacturing the retaining snap rings, have developed different types over the years, each a solution to a specific problem issues such as: tolerance take-up, clearance diameter, thrust load capacity, flexible installation, rpm capacity, impact loading, non-removable lock-rings, groove-less push-on fastening and radial installation.

Retaining ring, Retaining rings fasten assemblies on shafts or in housingbores. They are installed into a groove creating a shoulder that retains the assembly. Retaining rings are more efficient and cost-effective than traditional fasteners like screws, nuts, bolts, cotter pins, washers and more. Functions with a minimum amount of surface preparation to either shaft or housing.

(Single & double coil in Spring steel & Stainless steel) Retaining Rings are precision engineered components that are designed to be applied on shafts or in bores and provide a shoulder that accurately positions, locates and retains other parts of an assembly. BM, an expertise in manufacturing the retaining / snap rings, have developed different types over the years, each a solution to a specific problem / issues such as: tolerance take-up, clearance diameter, thrust load capacity, flexible installation, rpm capacity, impact loading, non-removable lock-rings, groove-less push-on fastening and radial installation. BM rings can be economically produced in carbon steel & stainless steel as these are been manufactured by coiling from flat wire, hence no burrs and no scrap. We offer thousands of parts available in both carbon and stainless steel with no tooling cost for your designs.   Benefits of Retaining Rings: Retaining rings fasten assemblies on shafts or in housing/bores. They are installed into a groove creating a shoulder that retains the assembly. Retaining rings are more efficient and cost-effective than traditional fasteners like screws, nuts, bolts, cotter pins, washers and more. Functions with a minimum amount of surface preparation to either shaft or housing.   Applications:  Automobile Industry – Applicable in many components Military, Aerospace applications

Business Machines have now been successfully manufacturing Crest to Crest Wave springs and one of the leaders in India to manufacture the same. Crest to Crest Wave Washers have multifold advantages over the conventional compression springs & widely used in Mechanical Seals, Valves & various other industries, typically for applications requiring low-medium spring rates and large deflections with low-medium forces. Crest-to-Crest Wave washers are pre-stacked in series, decreasing the spring rate proportionally to the number of turns. This will maintain the same force and load specifications of a conventional round wire washer with an additional advantage resultant lowered and compacted operating heights, free heights and solid heights.. As a replacement for helical compression springs, Crest-to-Crest springs can develop similar forces, yet occupy one-half (1/2) or less the axial space that allows for strict space constraints.
