Oil Grooved Brass Bushing – Process & Quality Assurance Statement
Our oil grooved brass bushings are designed to provide reliable, low-maintenance bearing performance in applications where consistent lubrication and wear resistance are key to long-term operation.

Key process features

Manufacturing combines precision casting or extrusion with careful machining to create effective groove patterns and accurate fits:
●Material Preparation: Leaded brass alloys are selected for their superior machinability and natural lubricity.
●Forming Blank: Blanks are cast or extruded to near-net shape for minimal material waste.
●Rough Turning: Initial machining establishes outer and inner diameters with allowances for finishing.
●Groove Cutting: Specialized tooling machines precise oil grooves (spiral, straight, or figure-8 patterns) to optimize lubricant retention and distribution.
●Finish Machining: Final honing or boring achieves tight tolerances and smooth bearing surfaces.
●Deburring & Cleaning: Edges are carefully deburred and parts cleaned to remove any residue.
●Packaging: Bushings are individually protected and boxed to arrive ready for installation.

Quality control system

● Full traceability from alloy batch to finished bushing
● Material certificates and dimensional reports supplied with each order
● Sample retention ≥3 years for third-party audit (SGS, BV, TÜV, etc.)
● 100% inspection of essential attributes:
• Chemical composition (optical emission spectrometry)
• Dimensional accuracy (CMM and bore gauges; typical ID tolerance ±0.02mm)
• Groove pattern and depth (profile measurement)
• Surface finish and roundness (profilometer checks)
• Visual defects and burrs (magnified inspection)
● Internal standards exceed ASTM B584 requirements. Typical C83600 properties: Good embeddability for dirt particles, Excellent conformability, Proven reliability in oil-lubricated sliding applications.
● ISO 9001:2015 certified operations ensure every oil grooved brass bushing delivers consistent quality, effective lubrication, and dependable service in your machinery.
