Shaanxi Xixian New District Zhongcheng Machinery Manufacturing Co., Ltd. delivers enterprise-grade Spool Type Steel Spring solutions engineered specifically for solid control shale shakers in oil and gas drilling operations. Across several drilling rig models, such as the ZJ90, ZJ70, and XJ series, our core support components absorb vibration and stabilize continuous operation. These springs have exceptional elasticity and anti-deformation qualities and are made with tensile strengths between 1,500 and 2,200 MPa. With ISO 9001/14001/45001 certifications and validation from HSE, TÜV, and BV auditing organizations, our factory-direct supply guarantees that you will receive springs that have been tested for more than 1,000,000 cycle fatigue life, offering dependable performance in temperatures ranging from -60°C to +150°C.
Our Spool Type Steel Spring sustains steady torque production over long operating cycles, in contrast to conventional helical springs that lose force consistency.
Each spring is precision-wound using high-carbon or SUS301 stainless steel ribbon. This design provides superior energy density in compact dimensions.
You benefit from a flat force-deflection curve. This means your shale shaker receives consistent dampening force across thousands of drilling hours.
In order to obtain exact Rockwell hardness (HRC), our production process incorporates specialized heat treatment. This equilibrium preserves elasticity while preventing brittle fracture.
The small construction fits effortlessly into tight equipment locations. The lightweight design and simple integration will be appreciated by your installation crew.

Your drilling operations face extreme conditions daily. Our springs are built to withstand them.
We select high-strength corrosion-resistant materials specifically for oilfield environments. Chemical erosion, high humidity, and temperature fluctuations won't compromise performance.
The SUS301 stainless steel variant features specialized passivation. This treatment prevents localized pitting in high-moisture conditions common at drilling sites.
For acidic or alkaline fluid exposure, we apply protective coatings during manufacturing. Your equipment maintains structural integrity even when exposed to drilling mud chemicals.
Salt spray testing per ASTM B117 validates our corrosion resistance claims. We don't just claim durability—we prove it through rigorous testing protocols.
High-carbon steel options undergo hydrogen embrittlement relief baking. This post-treatment process maintains ductility after plating, preventing unexpected brittle failure.
Vibration control directly impacts your shale shaker's operational efficiency and lifespan.
Our Spool Type Steel Spring design incorporates advanced dampening geometry. This reduces inter-coil friction that causes noise and premature wear.
Specialized dry-film lubricants are applied during the winding process. This treatment minimizes operational noise while maintaining consistent spring action.
The buffering performance protects connected components from destructive vibration. Your centrifuges, desanders, and mud cleaners experience less mechanical stress.
By absorbing shock loads effectively, these springs extend the service life of your entire solid control system. You'll reduce downtime and maintenance costs significantly.
Fatigue resistance testing exceeds industry standards. We subject samples to accelerated cycle testing to verify Mean Time Between Failure (MTBF) specifications.
Every drilling operation has unique requirements. We accommodate your specific needs.
You can select from various spring specifications including strip thickness, width, and diameter. Our engineering team adjusts the natural curvature to create positive, neutral, or negative torque gradients.
Need specialized dimensions for legacy equipment? Our design flexibility allows matching to existing shaker configurations across all major rig models.
As a direct manufacturer with 6,300 square meters of production facilities, we control quality at every stage. No intermediaries mean better pricing for you.
In-stock standard springs ship within 3 days. Custom orders typically deliver within 15 days, keeping your project timelines on schedule.
Our annual production capacity of 200+ solid control systems ensures reliable supply. You won't face delays due to manufacturing bottlenecks.
Technical support includes engineering drawings, component diagrams, and operation manuals. Your maintenance team receives complete documentation for optimal spring performance.
Professional purchasers prioritize verifiable quality standards. We deliver documented proof.
Torque Testing: Every batch undergoes output measurement at various rotation points. We verify compliance with specified pressure-length curves before shipment.
Fatigue Life Verification: Accelerated cycle testing confirms springs meet or exceed 1,000,000 operational cycles under rated load conditions.
Edge Profile Inspection: Optical microscopy examines strip edges for micro-cracks. The slitting process quality directly impacts failure rates—we inspect 100% of production runs.
Corrosion Resistance Validation: Salt spray chambers simulate years of environmental exposure. Only springs passing ASTM B117 standards receive certification.
Dimensional Precision: CNC-controlled winding equipment maintains tolerance levels critical for consistent performance. Variation stays within 0.02mm across production batches.
Our ISO 9001 Quality Management System ensures traceability. Each spring carries batch identification linking to complete manufacturing records and test data.
Q: What determines the replacement interval for springs in continuous operation?
A: Failure typically manifests as torque loss (called 'set') or ribbon breakage. We recommend replacement at 80% of tested fatigue life for mission-critical applications. For 24/7 shaker operation, this typically means scheduled replacement every 18-24 months depending on load conditions.
Q: How do you minimize operational noise in high-frequency vibration applications?
A: Noise results primarily from inter-coil friction. We apply PTFE coatings or specialized dry-film lubricants during winding. This treatment reduces friction coefficients by up to 60% compared to uncoated springs, significantly lowering operational decibel levels.
Q: Can springs be engineered for specific torque profiles?
A: Definitely. We adjust the force-deflection characteristics by changing the strip thickness, width, and pre-stress curvature diameter. You can indicate if you require torque that is constant, increasing, or decreasing across the operating range.
Q: What material performs best in high-humidity offshore environments?
A: Our unique passivated finish on SUS301 stainless steel offers exceptional corrosion resistance. In high-moisture drilling settings and maritime environments, this combination keeps structural integrity and avoids pitting.
Q: How does your spring differ from standard clock springs?
A: While geometrically similar, our Spool Type Steel Spring is optimized for higher torque output and longer rotational travel. We employ specialized back-winding techniques that flatten the force curve, providing more consistent performance across extended operational ranges compared to standard clock spring designs.
