China Machining Copper Bushing
The China Machining Copper Bushing from Xinxiang Haishan Machinery Co., Ltd. is manufactured from high-density copper alloy strip, precision-machined to form bearing surfaces with diamond-shaped or hemispherical oil holes and grooves. These features enhance lubricant retention and distribution under high-load conditions, critical for performance in oil well machinery and mining equipment. The material composition is a Cu-based alloy with no specified additives, relying on inherent density and structural integrity for load-bearing performance.
This bushing replaces traditional cast copper sleeves by using rolled alloy strip as a substrate, reducing material waste and machining time. The surface treatment allows direct integration of oil channels without secondary bonding, improving reliability. Typical industry standards for similar components require a minimum bearing pressure of 35 MPa and wear resistance rated for over 10,000 hours under dry or semi-lubricated conditions, though exact test data for this product is not provided. The alloy’s density is described as high, consistent with CuSn8 or CuPb10Sn10 grades commonly used in industrial bearings.
Buyers in construction machinery, metallurgical equipment, and cement plant operations specify this bushing for its durability in high-vibration environments. It is typically ordered in bulk for replacement cycles in heavy-duty rotating assemblies. Packaging is standard in cartons with internal anti-rust paper, but exact MOQ, lead time, and Incoterms are not stated in the listing. Buyers should confirm these terms directly with the supplier before placing orders.
| Material | High-density copper alloy strip (Cu-based) |
| Manufacturing Process | Precision machining from rolled alloy strip |

| Typical Bearing Pressure | Standard range for industrial copper bushings: 30 to 50 MPa |
| Typical Wear Life | Typical service life under heavy load: 8,000 to 15,000 hours |
| Surface Finish | Machined to tolerance, no surface coating specified |
| Typical Dimensions | Standard bore diameters range from 10 mm to 100 mm; length varies by application |
| Typical Tolerance | Standard bore tolerance: H7 or H8 per ISO 286 |
| Packaging | Cartons with anti-rust paper, bulk palletised |
| Compliance Standard | Typical compliance: DIN 1494 or ISO 3547 for copper alloy bushings |

Sourcing China Machining Copper Bushing from Xinxiang Haishan Machinery Co., Ltd. - China Import Guide
Before ordering, verify the exact alloy composition and hardness of the copper bushing with a material test report. Confirm that the oil groove geometry matches your equipment’s lubrication system, as mismatched designs can cause oil starvation. Request samples of at least three units for fit and function testing under simulated load. Do not rely on generic product descriptions without batch-specific data.
Lead time and Incoterms are not disclosed in the listing. Buyers must confirm whether FOB Qingdao or CIF is available and request written terms. Payment methods should be negotiated through secure channels like LC at sight, as advance payment carries risk with unverified suppliers. Typical lead time for custom machining is 25 to 40 days, but this must be confirmed in writing before production starts.
Inspect incoming shipments for dimensional accuracy using calipers and micrometers, and check for surface defects such as burrs or machining marks. Request batch-specific test reports for hardness, oil groove depth, and material composition. Ensure each carton is labeled with batch number and material grade. Retain samples for third-party inspection if used in safety-critical machinery.
