Its main products include brass, aluminum bronze, tin bronze, and others produced according to national standard grades. It processes and produces various solid inlaid self-lubricating bearing products on this basis . At the same time, it uses sintering technology to produce bimetallic products and many other types of products. Since its establishment nearly 10 years ago, the company has focused on the research development, and production of various new self-lubricating bearings.

In the process of product production, our company has always insisted on independent casting production of raw materials to ensure the quality of products from the source; during the casting process, the whole process is monitored, and the finished product is tested by spectrometer three times before, in and after the furnace to confirm the material composition of the product. The national testing agency is regularly commissioned to test the material composition and mechanical properties of the product, and authoritative test reports can be provided to customers in need; the company implements integrated production from material to finished product processing and has more than 80 sets of advanced CNC machine tools, CNC lathes, machining centers, and other major equipment. The strong production capacity ensures that the material production is organized for customers for the first time, shortening the production cycle.

JDB-600 Casting Bronze Bearing Industry knowledge

JDB-600 Casting Bronze Bearing Manufacturer

Zhejiang Shuangnuo Bearing Technology Co., Ltd. is a specialized JDB-600 Casting Bronze Bearing manufacturer and supplier, producing high-performance tin bronze bushings with internal spiral oil grooves. Our range is designed for heavy-duty applications requiring high load capacity, corrosion resistance, and reliable lubrication distribution. We combine in-house casting, precision machining, and rigorous quality control to deliver components that meet demanding engineering specifications.

With nearly a decade of experience, we focus on the research and production of self-lubricating copper alloy products. Our factory in Zhejiang, China, integrates material production and finished part processing, ensuring consistent quality and shorter lead times. We serve global clients in machinery, automotive, marine, and industrial equipment sectors, offering ODM/OEM customization to fit specific application needs.

Product Range and Positioning

Our JDB-600 series includes a variety of bronze grades and configurations, each tailored to different operating conditions. The core product is a tin bronze bushing with machined internal spiral oil grooves, designed for oil-lubricated systems. We also offer solid-lubricant embedded versions for maintenance-free operation.

Grade Material Composition Typical Application
JDB-600U1 CuZn25Al6Mn4Fe3 High-strength, wear-resistant for heavy machinery
JDB-600U2 CuSn5Pb5Zn5 General-purpose, good machinability
JDB-600U3 CuAl10Ni5Fe5 Corrosion-resistant for marine and chemical
JDB-600U4 CuSn12 High load, low speed applications
JDB-600U5 CuSn10Pb10 Good anti-friction for bushings
JDB-600U6 CuZn25Al6Mn4Fe3 Extra high strength and hardness

Application Fit and Engineering Value

Our JDB-600 bushings are used in industrial gearboxes, hydraulic pumps, compressor connecting rods, electric motor sleeves, conveyor rollers, agricultural machinery, and marine engines. The internal spiral oil grooves ensure uniform oil distribution, reducing friction and preventing metal-to-metal contact. This design is ideal for continuous or intermittent oil supply systems.

We offer customization of groove patterns, dimensions, and lubrication configurations. Our engineering team provides consultation for non-standard designs, ensuring the bushing fits your specific load, speed, and environmental conditions.

Quality Assurance and Testing

We independently cast our raw materials to control quality from the source. During casting, we perform three spectrometer tests—before, during, and after the furnace—to confirm material composition. We also regularly commission national testing agencies to verify mechanical properties and provide authoritative test reports upon request.

  • Material composition verified by spectrometer analysis
  • Mechanical properties tested by independent laboratories
  • Dimensional accuracy ensured by CNC machining

Production Capability and Integration

Our factory is equipped with over 80 advanced CNC machines, lathes, and machining centers, enabling integrated production from raw material to finished product. This capability allows us to organize material production promptly and shorten lead times. We support both small-batch prototypes and large-volume production runs.

Information We Use to Configure Your Solution

To prepare a precise proposal, we need the following details:

  • Bushing inner and outer diameter, length, and tolerance requirements
  • Operating load, speed, and temperature range
  • Lubrication method (oil, grease, or self-lubricating)
  • Environmental conditions (corrosive, dusty, etc.)
  • Desired material grade or performance criteria
  • Quantity and delivery schedule

Installation and Maintenance

Our bushings are designed for press-fit installation with housing bore tolerance ISO H7. Proper installation ensures uniform contact and prevents damage to oil grooves. For maintenance, replace when bore wear exceeds 0.08 mm or groove depth reduces by 50%. We provide guidance on installation and service intervals.

FAQs

What is the advantage of spiral oil grooves over straight grooves?

Spiral grooves provide more uniform lubricant distribution across the entire bearing surface, reducing localized friction and wear compared to straight grooves.

What type of oil is recommended for these bushings?

Standard industrial gear oils or hydraulic oils with ISO VG 32-68 viscosity are typically recommended. Consult our engineers for specific application requirements.

Can oil holes be added to the bushing?

Yes, radial oil holes can be added to allow external oil supply directly into the groove pattern. Hole locations and sizes are customizable based on your application.

What is the recommended installation method?

Press fit using a tool that contacts the bushing end uniformly. Ensure the housing bore is within ISO H7 tolerance and that oil grooves are not damaged during installation.

How do I determine when to replace an oil groove bushing?

Replace when bore diameter wear exceeds 0.08 mm, when the oil groove depth has reduced by more than 50%, or when scoring or galling is visible.
