description

 

Machined bushings provide wear-resistant bearing surfaces in linear and rotary applications - wherever moving parts need to slide or rotate with minimal friction and precise guidance. The bushing material, surface finish, and lubrication all determine how long the assembly runs before maintenance is needed. Bronze bushings handle most general industrial applications - good machinability, reasonable cost, adequate wear resistance for moderate loads and speeds. Brass bushing offer better corrosion resistance and are common in instrumentation and marine applications. Steel and stainless steel bushings take on higher loads and more demanding environments. Oil-impregnated bronze bushings (sintered bronze) provide self-lubricating operation - the pores in the sintered material hold oil that releases under load, eliminating the need for external lubrication systems.

Bushing Material Comparison

 

Bronze: good all-around, machines well, moderate cost. Brass: better corrosion resistance, common in marine and instrumentation. Oil-impregnated bronze: self-lubricating, best for inaccessible locations or where contamination is unacceptable. Steel: for higher loads, needs lubrication. Stainless: for corrosive environments.

Quality is non-negotiable in precision manufacturing. Every component undergoes rigorous inspection at each stage of production.

  • ISO 9001:2015 - Quality management system covering design and manufacturing
  • API 6D / API 600 - Design and testing compliance for valve components and flanges
  • Hydrostatic Pressure Testing - Every valve body pressure-tested to 1.5× rated pressure
  • MPI / LPI - Magnetic particle and liquid penetrant inspection for weld integrity
  • CE / ATEX - Pressure equipment directive compliance for EU market available
  • CMM Inspection - Coordinate measuring for complex geometries and tight tolerances
  • Surface Roughness Measurement - Ra, Rz, and Rt charting with every inspection report
  • Passivation / Electropolishing - ASTM A967 procedures for corrosion resistance
  • Material Traceability - Heat number tracking from raw material to finished part

 

From raw material to finished product, every step is controlled and documented:

  • Material Preparation - CNC turning/milling to near-net shape
  • Heat Treatment - Through-hardening or case-hardening for strength-critical parts
  • Surface Preparation - Degreasing, acid cleaning, and surface activation
  • Electroplating - Controlled bath process with thickness monitoring
  • Sealing / Baking - Chrome sealing, anodize sealing, or hydrogen embrittlement relief baking
  • Inspection - Coating thickness measurement, adhesion testing, and visual check
  • Packaging - Protective interleaving, VCI packaging, and anti-tarnish wrapping
