🌀 Conical Disc Washer (Belleville Washer) – High Load Spring Washer | Neo Fasteners
Neo Fasteners supplies premium-quality Conical Disc Washers, also known as Belleville Washers, designed to deliver high spring force in limited space. These washers are shaped like a truncated cone and provide axial flexibility, enabling them to maintain tension, preload, and bolt security even under fluctuating loads, temperature changes, or vibration.
Used extensively in heavy-duty bolted joints, wind turbines, high-pressure flanges, electric motors, railway brakes, gearboxes, and dynamic mechanical assemblies, these washers are a key solution for bolt tension retention and shock absorption.
🔧 Key Features
- Conical Shape: Delivers spring force and compensates for relaxation or creep
- Load Management: Absorbs shock and maintains clamp force under vibration
- Stackable: Can be used in series or parallel for customized load/deflection profiles
- High Fatigue Life: Ideal for dynamic and cyclic loading environments
- Compact Alternative to Coil Springs
