Custom Designs One PTFE Sliding Bearing at a Time

Rolled dry sliding bushings ptfe

The sliding bushings are encapsulated sliding bearings made of a three-layer composite produced from a steel strip, a sintered-on porous bronze layer and a surface sliding layer made of PTFE and Pb (lead).

This type of sliding bushing has a low friction coefficient and protection against wear and corrosion, and can be used without oil. The low manufacturing costs and top-of-the-range technical foundations mean that these sliding bushings are used in a variety of different kinds of sliding applications, such as in textile manufacturing machinery, hydraulic systems and automotive machinery as well as agricultural and forestry machinery.

DESIGN GUIDE: SELF-LUBRICATING BEARINGS TYPE

Maintenance-free, space-saving dry sliding bearings

There are two standard types of composite material for dry sliding bushing: PTFE composite and POM composite.
  • Straight self-lubricating bushings
  • Flanged dry sliding bushings
  • Thrust washers
  • Strips
polyethylene bushings

polyethylene bushings

The dry plain bearing has a common structure consisting of a steel substrate bonded to a sintered porous bronze layer impregnated and coated with PTFE / lead-bearing material. Dry plain bearings utilize the unique properties of dry PTFE bearing and combine them with strength, stability, and good wear resistance, excellent thermal conductivity, and low thermal expansion.
  • Dry slide bearing requires no lubrication
  • High static and dynamic load capacity

Dry sliding bearings can meet strict criteria for long life and trouble-free operation, with or without lubrication, in a variety of equipment such as hydraulics, valves, automotive, agriculture, material handling, and many more.

Properties of  dry sliding bearings

  • Long service life and maintenance-free operation
  • High load-bearing capacity
  • Low wear
  • Low coefficient of friction
  • Stick-slip free sliding behavior
  • Good chemical resistance of sliding surfaces

We are leading manufacturers, suppliers of Dry Sliding Bearings which is a composite structure consist of a carbon steel backing, an intermediate layer of sintered bronze and a PTFE modified sliding layer.

It offers the good properties of self-lubricating, abrasion-resistant, low-friction, and offers the advantages of metal and multi-element polymer, as well as an excellent cost-performance ratio.

Dry bushes take advantage of the out-standing dry bearing properties of PTFE and combine them with strength, stability, and good wear resistance.

Wrapped Composite Dry Sliding Bearing, Steel/Ptfe, Maintenance-Free

Excellent sliding and wear behavior, for all types of movement, high load capacity, all-around adaptable.

A range of PTFE coated wrapped bearings suitable for dry running, low friction, and low wear applications. These wrapped bearings have excellent sliding characteristics forming a transfer film that can protect the corresponding metal surface.

PTFE coated bearings were developed for high-performance oil lubrication applications. These applications include, but are not limited to:

  • Automotive suspension legs
  • Shock absorbers
  • Hydraulic cylinders
  • Gear pumps and motors
  • Axial and radial piston pumps and motors
Cylindrical and flanged bushings, thrust washer, strips are a standard fabrication.
