Product Description
High Torque Disc Spring: The Key to Secure High-Torque Bolted Connections
Bolted connections in high-torque applications—where preload forces exceed 50,000 N and operational vibrations reach 200 Hz—are inherently prone to loosening. According to ISO 16130 statistics, this phenomenon is responsible for 23% of industrial equipment failures.
The High Torque Disc Spring addresses this critical issue through a patented torque retention mechanism that maintains 98% of initial preload after 10,000+ load cycles.
Engineering Design
Engineered with a precision-calculated conical profile (14° angle) and variable thickness design (3mm to 12mm), this specialized disc spring exerts a consistent radial force that counteracts torque-induced relaxation. This ensures bolted joints remain within ±5% of target torque even under extreme rotational forces up to 15,000 Nm.
Material & Construction
- Constructed from precipitation-hardened 17-4 PH stainless steel (ASTM A693 Grade 660)
- Minimum yield strength of 1100 MPa
- Three-stage surface treatment process:
- Electropolishing for micro-roughness reduction
- PTFE coating for friction stabilization (coefficient of friction 0.12±0.02)
- Passivation to achieve 2000+ hours of salt spray resistance per ASTM B117
