Product Description
Spring Washers, also known as lock washers, are a specialized type of washer designed to provide a pre-load and maintain tension between two surfaces. Unlike flat washers, spring washers offer resistance to rotation and vibration, helping to prevent loosening of the fastener.
Available in multiple designs such as Split Lock (DIN 127), Belleville (DIN 2093), Wave, and Curved washers, these components play a critical role in dynamic assemblies where movement and thermal expansion could cause loosening.
SM Fasteners supplies high-performance spring washers manufactured using high-grade materials and finishes to ensure optimal elastic recovery and corrosion resistance in demanding applications.
Applications
Spring washers are used in applications where securing fasteners against vibration and dynamic loads is critical, such as:
Automotive & railway assemblies
Heavy equipment & vibrational machinery
Elevator systems & gearboxes
Oil and gas valve systems
Switchgear, generators, and turbines
Aerospace and aviation equipment
Renewable energy & wind turbine systems
