Compressor sleeve

As a key component stemming from Shaoxing Shangyu Flight Seiko Machinery Co., Ltd. (FTM), our Compressor Sleeves are the embodiment of our commitment to high-precision, custom-engineered bearing solutions. Leveraging over 30 years of specialized technical design experience, FTM delivers crucial components that directly enhance the efficiency, stability, and longevity of demanding compressor systems across various industries.

Product Overview and Technical Excellence

The sleeve, or bushing, within a compressor is a critical functional part that supports rotating shafts, reduces friction, and manages the thermal and mechanical loads imposed during operation. FTM’s commitment to manufacturing excellence ensures our compressor sleeves provide performance advantages far superior to industry standards.

• Impact on Performance: The precision of the sleeve’s dimensions, surface finish, and material integrity are paramount. An FTM-engineered sleeve minimizes frictional losses, controls vibration, and maintains optimal shaft alignment, directly contributing to the compressor’s energy efficiency and reducing maintenance downtime.
• Broad Application Scope: While central to compressor systems, FTM’s customizable sleeve technology extends to various high-demand applications, including:
  • New Energy Vehicles (NEVs): Crucial for electric A/C compressors and motor assemblies.
  • Aerospace and Aviation: Where extreme reliability and lightweight, high-strength materials are essential.
  • Construction Machinery: Enduring high shock loads and operating in challenging environments.
  • Marine and Shipbuilding: Requiring robust, corrosion-resistant components.
  • Robotics and Automation: Demanding high precision and zero-defect components.

Customization and Material Specifications

FTM specializes in non-standard, tailor-made solutions, ensuring the sleeve perfectly integrates with your specific compressor design and operational needs.

• Optional Material: Bearing Steel (e.g., GCR15), Stainless Steel, Specialty Metals. Selection based on required hardness, wear resistance, corrosion resistance, and operational temperature. GCR15 offers excellent wear life and high contact fatigue strength.
• Custom Size Range: 10 mm to 250 mm (O.D.I.D.). Accommodates a vast spectrum of compressor sizes, from micro-applications to heavy industrial units.
• Precision Features: Channel, Chamfer, Roughness (Ra), Precision Grade. Customizable geometric features and surface finish to optimize oil film formation, fluid dynamics, and minimize edge stress concentration. Custom roughness ensures superior boundary lubrication conditions.
• Surface Treatment: Optional coatings (e.g., Black Oxide, Phosphate, Hard Chrome). Enhanced resistance to friction, wear, and corrosion, extending component life in harsh operating conditions.

Frequently Asked Questions (FAQ)

• What is the typical lead time for a custom batch of compressor sleeves?

  • Lead time is application dependent. Generally, prototype design and first article approval take 4 to 6 weeks, with subsequent production batches delivered in 3 to 5 weeks, based on material availability and complexity.

• Can FTM help determine the best material for a high-temperature, high-speed compressor application?

  • Absolutely. This is a core part of our service. Our technical team will analyze your operational parameters (PV value, temperature, medium) and recommend the optimal material (e.g., GCr15, specialty stainless steel, or even ceramic coated options) to maximize fatigue life.

• What level of precision (tolerance) can FTM guarantee for a custom sleeve?

  • We are capable of achieving high-precision tolerances typically seen in ISO P4 (ABEC 7) and often higher, especially for critical dimensions like bore diameter and concentricity, which is essential for high-speed stability.

• How does the surface roughness (Ra) affect the sleeve’s performance?

  • Surface roughness is crucial for hydrodynamics. A specific, smooth Ra is necessary to maintain a stable lubricating oil film, minimizing boundary friction and preventing premature wear, which significantly extends the sleeve’s operational life.

• Does FTM offer solutions for sleeves that require integrated cooling channels or oil feed holes?

  • Yes, our customization includes complex internal and external geometries, such as precisely machined oil feed holes, lubrication grooves, and specialized chamfers, all designed to enhance cooling and lubrication efficiency within the compressor system.
