Product Description
Custom Precision Machined Steam Turbine Oil Seals
Our custom steam turbine oil seals (oil sealing rings) are key sealing components for steam turbine bearing chambers, bearing housings and shaft systems. Adopting high-strength bronze/copper alloy raw materials, they are fully customized according to unit parameters, shaft size and drawing requirements, widely matched with supercritical, ultra-supercritical thermal power units and industrial steam turbines.
The product forms a tiny uniform clearance with the rotating shaft to block lubricating oil leakage, prevent steam and dust from entering the bearing chamber, stabilize oil pressure and oil level, reduce oil consumption, and protect bearing and rotor service life under long-term continuous operation.
Core Customization Strengths
Full Customization Support
- Custom outer diameter, inner thread, thickness, positioning hole, oil drain groove and step structure
- Compatible with all mainstream turbine brands retrofitting spare parts
- Two types available: labyrinth oil seals and solid copper oil sealing rings
- Mixed customized orders are acceptable
Premium Copper Alloy Raw Materials
- Standard material options: High-lead bronze, tin bronze, aluminum bronze, wear-resistant cast copper alloy
- High hardness, low friction coefficient, self-lubricating performance
- No shaft scratching during long-time rotation
- Complete material test certificates (MTC) provided
Ultra-Precision CNC Machining Technology
- Multi-axis CNC turning & internal thread precision machining
- Tolerance controlled within ±0.003mm
- Fine turning surface without burrs
- Optional precision labyrinth tooth processing
- Strict flatness and concentricity inspection
Outstanding Service Performance
Low Friction & Wear Resistance
Self-lubricating copper material reduces shaft abrasion, no galling even under long high-speed operation
High Temperature Resistance
Stable sealing performance under bearing chamber working temperature up to 180℃
Anti-Corrosion & Anti-Oxidation
Resists erosion of turbine lubricating oil, no rust or deformation after years of operation
Remarkable Oil Saving Effect
Greatly cuts turbine oil leakage rate, reduces power plant oil replenishment cost and environmental pollution
Long Service Cycle
2-4 times longer service life than ordinary cast iron seals, lowering shutdown maintenance frequency
