(din7980 spring washer)
DIN 7980 spring washers serve as critical components in mechanical assemblies requiring controlled axial tension. These disc springs maintain clamping force in bolted joints across temperature fluctuations (±250°C) and vibrational environments (up to 55 Hz). Industrial data shows proper washer implementation reduces fastener loosening incidents by 72% in heavy machinery applications.
Leading DIN 7980 spring washer factories employ cold-formed carbon steel (C75S) with 12-14% compression modulus, exceeding standard DIN 2093 specifications. Advanced manufacturers utilize:
Supplier | Production Capacity | Lead Time | Price/1k units | Certifications |
