FB090 Bronze Wrapped Bushing Bearing Manufacturers

FB090 bronze bearings use specially formulated high-density copper alloy strips as the base, and can be rolled with diamond or hemispherical oil pockets and oil grooves on the surface according to user needs. This product has the advantages of high density, strong load-bearing capacity, good wear resistance, and long service life. It can replace traditional cast copper sleeves, thereby reducing the size of the machinery and reducing costs.

FB090 has been widely used in lifting machinery, engineering machinery, automobile tractor chassis, machine tool industry, mining machinery and other fields. In addition, it can also be processed into bearings, flange sleeves, thrust washers, ball bowls and other parts.

FB090 Bronze Wrapped Bearing Industry knowledge

Zhejiang Shuangnuo Bearing Technology Co., Ltd. is a specialized FB090 Bronze Wrapped Bearing manufacturer and supplier, producing self-lubricating bushings from high-density CuSn8 bronze strip. Our range covers cylindrical, flanged, and thrust washer forms, with custom oil pockets, grooves, and sealing options to suit lifting, construction, agricultural, and general machinery applications.

Product Range and Positioning

We manufacture a complete family of bronze wrapped bearings under the FB090 series, each engineered for specific load and lubrication conditions:

Type Key Feature Typical Application
FB090 Diamond or hemispherical indentations for grease retention Hoisting, construction, machine tools
FB091 High thermal conductivity copper alloy Hydraulic cylinders, agricultural machinery
FB092 Drilled oil holes for pre-filled lubrication Conveyors, hoists, medium-load low-speed
FB094 Lead-free, high load capacity Heavy-duty industrial equipment
FB09G Graphite plugged for dry running Oscillating and linear motion
FB08G Steel-backed with graphite High-load, low-speed pivots
FB090F Metric flanged design Axial location and thrust loads

This range allows us to match the bearing structure to your duty cycle, whether you need periodic relubrication, pre-filled oil reservoirs, or completely dry operation.

Engineering and Manufacturing Approach

As a vertically integrated factory, we control quality from raw material to finished part. We independently cast our CuSn8 and CuSn6.5P alloys, then cold-roll them into strip, ensuring high density and consistent composition. Our in-house spectrometer testing—performed before, during, and after casting—verifies material chemistry, and we can provide authoritative test reports from national agencies on request.

With over 80 CNC lathes and machining centers, we handle precision machining of bores, flanges, and oil grooves. This integrated production shortens lead times and allows us to customize dimensions, wall thickness (typically 1.0–2.5 mm), and surface patterns without outsourcing.

Application Fit and Material Considerations

FB090 wrapped bearings are designed to replace traditional cast bronze sleeves in compact housings. The thin-wall construction reduces weight by up to 75% while maintaining high radial load capacity (up to 120 N/mm² static). The cold-worked CuSn8 material achieves a hardness of 90–120 HB, offering superior wear resistance compared to cast alloys.

For applications involving:

  • High loads and low speeds – choose FB090 or FB092 with oil holes for pre-lubrication.
  • Heat dissipation – FB091 provides higher thermal conductivity (71 W/m·K).
  • Dry running or contamination – FB09G or FB08G with graphite plugs.
  • Axial location – FB090F flanged version simplifies installation.

We also produce thrust washers, ball bowls, and custom shapes from the same material.

Configuration and Customization

We offer ODM/OEM services, tailoring each bearing to your drawing or application. Configuration options include:

  • Inner and outer diameter, length, and wall thickness
  • Indentation pattern: diamond, hemispherical, or custom
  • Oil grooves, oil holes, or graphite plugs
  • Flanged, cylindrical, or thrust washer forms
  • Sealing provisions (e.g., FB094 with seals)

Our engineers review your operating parameters—load, speed, temperature, and lubrication method—to recommend the optimal material grade and surface treatment.

Quality Assurance and Compliance

We manufacture to ISO 3547 for wrapped bushings, ensuring dimensional consistency and interchangeability. Our quality system includes:

  • Three-stage spectrometer analysis during casting
  • Regular third-party testing of mechanical properties
  • Dimensional inspection on CNC equipment
  • Traceability from melt to finished batch

We can supply material certificates and test reports for your quality records.

Installation, Maintenance, and Service

FB090 bushings are designed for press-fit installation into a rigid housing. The thin wall gains support from the bore, so we recommend a housing tolerance of H7 and shaft tolerance of f7 or h8, depending on clearance requirements. For FB092, oil or grease is packed into the drilled holes before sealing the ends; periodic relubrication can extend service life in dusty environments.

We provide installation guidance, lubrication schedules, and spare part support. Our team can assist with failure analysis if an application changes.

Information We Use to Configure Your Solution

To prepare an accurate quotation and engineering proposal, please provide:

  • Bearing dimensions (ID, OD, length, flange if any) or a drawing
  • Load (radial/axial) and direction
  • Shaft speed and motion type (rotating, oscillating, linear)
  • Operating temperature and environment (dust, moisture, chemicals)
  • Lubrication method (grease, oil, or dry)
  • Housing and shaft material and tolerances
  • Required quantity and target lead time

With this data, we can recommend the correct FB090 variant and confirm performance characteristics.

Frequently Asked Questions

1. What is the difference between FB090 and FB092?

FB090 uses surface indentations to retain grease, while FB092 has drilled oil holes that are pre-filled and sealed. FB092 is suited for medium-load, low-speed applications where you want to avoid frequent relubrication.

2. Can you produce non-standard sizes?

Yes, we offer custom dimensions. Our integrated machining allows us to produce any bore, length, or flange configuration within our strip width and thickness range.

3. Do you provide material certificates?

We provide spectrometer test reports for each batch and can arrange third-party testing for mechanical properties. Authoritative reports are available on request.

4. What is the typical lead time?

For standard sizes with stock material, lead time is typically 2–3 weeks. Custom orders may take longer depending on complexity and quantity.

5. How should FB090 bushings be installed?

They should be press-fitted into a housing with a recommended interference fit. Ensure the housing bore is clean and chamfered to avoid damage during insertion.
