Description

 

Wrapped bronze bushing is made of bronze plate with oil pockets or holes. It is a kind of wrapped greased (also sometimes graphite) lubricating bushing bearing. Bronze material normally in CuSn6.5P or CuSn8P, the bronze is made as the particular formulation with high specific and gravity, and on its surface may be incorporated with spherical or diamond shaped indentations or/and oil grooves as required by customers. The products are widely used in construction machinery, agricultural machinery and so on.

Wrapped bronze sliding bearing, with lubrication pockets • Low-maintenance • DIN 1494 / ISO 3547

PROPERTIES Good load capacity and stability at low abrasion, suited for rough operation, corrosion resistant.

Matereial CuSn8P (DIN 17662)

  • Cylindrical bushing
  • Flange bushing
  • Thrust washer
  • Strips

Materials

Wrapped bronze bearings are made entirely from phosphor bronze CuSn8. CuSn8 is characterized by the purity of the alloy with only a very low level of impurities. Wrapped bronze bearings are produced from strips that are subsequently wrapped and calibrated.

Lubrication

Wrapped bronze bearings must be lubricated with grease or oil on installation. A good quality lubricant is essential as it will reduce friction and wear by forming a film between the plain bearing and the shaft. For heavily contaminated applications, we recommend sealing off the bearing. This will protect both the bearing and the lubricant.

Advantages

The main advantages of wrapped bronze bearings include:

  • Long service intervals
  • Not affected by impurities
  • Suitable for corrosive environments
  • Suitable for impact loads and vibrations at low speeds
  • Good heat dissipation

Wrapped bronze bushes

Wrapped bronze bushes and flanged bushes are ideal for applications where there are high levels of contamination. Their sliding surface is provided with diamond-shaped lubrication pockets or a hole pattern.

Maintenance

090 & 090 bronze series bearings are low-maintenance bronze sliding bearings, primary lubrication is necessary.

Oil or grease lubrication is possible. Due to lubrication diamond pockets lubrication intervals are reduced to a minimum!

Wheter grease or oil is used, a good quality lubricant will reduce friction and wear by separating a bronze bushing from its shaft.

Advantages of wrapped bronze bushings include:

  • insensitive to contaminated environments
  • resistant to shcok loads and vibrations at slow speeds
  • good resistance to corrosive environments

Mounting Advice

Housing Shaft Force fitting mandrel Mounting chamfer, min. 1. 5 mm x 15-45°

Mounting chamfer, 5 mm x 15°, edges rounded Application of an adequate force fitting mandrel is advisable.

Grease lubrication of the outer surface may be necessary when mounting.

Long service intervals under severe operating circumstances.

Wrapped bronze bearings are ideal for applications where there are high levels of contamination. Their running surface is provided with diamond-shaped lubrication pockets or a hole pattern. The lubrication pockets must be filled with grease when the bearing is installed. The wrapped bronze bearings are produced according to the ISO 3547.

Application

Bronze Bushing for Agriculture machinery, truck cranes & construction machinery, suitable for impact loads.

Wrapped bronze bearings are especially suited to severe operating conditions where frequent maintenance is not possible. Common applications are:

  • Agricultural vehicles
  • Lifting gear
  • Offshore
  • Excavators
