JF-700 Bi-Metal Bearing Heavy Duty Self-Lubricating Sleeve Bushings

Product Description:

JF-700 is a bimetal bearing with steel as backing and sintered CuPb30 as a lining layer. It has good performance in anti-seizing, alien substance contamination.
It is necessary to be overplayed certain soft alloys and mostly applied in internal combustion engine under high speed and middle to low load, e.g. main bearing
of the inner-combustion engine and connect-rod bearing.

Product Introduction

JF-700 Heavy Duty Bi-Metal Bushings | Self-Lubricating Sleeve Bearings for Industrial Applications

The JF-700 Bi-Metal Bearing is a premium-grade self-lubricating sleeve bushing designed for heavy-duty industrial applications where reliability and longevity are critical. These durable industrial bushings combine high load capacity with maintenance-free operation, making them ideal for harsh operating conditions.

  • Maintenance-free operation: Embedded solid lubricants provide continuous lubrication
  • Exceptional wear resistance: Bi-metal construction extends service life
  • High load capacity: Withstands heavy radial and axial loads
  • Corrosion resistant: Performs well in wet or corrosive environments
  • Temperature resistant: Stable performance from -40°F to 300°F (-40°C to 150°C)
  • Cost-effective solution: Reduces downtime and maintenance costs

The JF-700 bi-metal bushings are widely used in demanding applications across various industries:

  • Construction equipment: Excavators, loaders, cranes
  • Agricultural machinery: Tractors, combines, harvesters
  • Material handling: Conveyor systems, forklifts
  • Heavy trucks: Suspension systems, fifth wheels
  • Industrial machinery: Pumps, compressors, hydraulic cylinders
  • Marine applications: Deck machinery, steering systems

Installation and Maintenance Guidelines

For optimal performance of your self-lubricating sleeve bearings:

  • Ensure proper alignment during installation
  • Clean housing surfaces before assembly
  • Use appropriate installation tools to prevent damage
  • Check for proper clearance after installation
  • Regularly inspect for abnormal wear (though no lubrication is required)

Frequently Asked Questions

Q: What makes bi-metal bushings different from regular bronze bushings?
A: Bi-metal bushings combine the strength of a steel backing with the wear resistance of a bronze layer, offering higher load capacity and longer service life.

Q: How long do these self-lubricating bushings typically last?
A: Service life varies by application, but typically lasts 3-5 times longer than conventional lubricated bushings in similar conditions.

Q: Can these bearings be used in food processing equipment?
A: Standard JF-700 bushings are not food-grade. Ask about our NSF-certified options for food industry applications.

Q: Do you offer custom sizes or special configurations?
A: Yes, we can manufacture bushings to your exact specifications including special materials, flanges, or unique dimensions.
