Introduction
The double ball joint suspension is a core component designed specifically for gas spring systems. Made with high-precision technology and high-quality materials, it ensures stable support and flexible rotation under dynamic load conditions. This product has excellent wear resistance and corrosion resistance, effectively reducing friction losses and extending the overall service life of gas springs, making it an ideal supporting component for industries such as machinery, automobiles, and furniture.
Core Advantages
High-Precision Processing Technology
Using CNC precision grinding technology, the tolerance of the inner and outer rings of the bearing is controlled within 0.001mm, ensuring precise matching with the gas spring piston rod and reducing vibration and noise during operation.
Premium Material Configuration
The bearing component is manufactured from GCr15 bearing steel, heat-treated at 1200℃ to attain a surface hardness range of 62-65 HRC. Enhanced corrosion protection is achieved through a hard chromium plating process (5-8μm thick coating), providing substantial improvement in durability when operating under challenging environmental conditions including high humidity and particulate contamination.
Friction-Optimized Structural Design
Optimized raceway curvature and ball ratio result in a friction coefficient as low as 0.008. Combined with lithium-based grease (drop point 180℃), it enables smooth rotation while reducing energy loss, ensuring a stable and non-jamming adjustment process for gas springs.
Longevity Assurance
Passed 1 million cycles of fatigue testing (1.5 times the rated load), with an average service life 30% longer than conventional products, reducing equipment maintenance frequency and replacement costs.
