Metal - Polymer Bearings

PTFE-BASED METAL-POLYMER MATERIALS: DU®, DU-B, DP4, DP4-B, DP31, DP10, DP11
Our metal-backed, PTFE-based (polytetrafluoroethylene) polymer bearing materials have a common structure, consisting of a metal backing bonded to a porous bronze sinter layer. This bronze sinter layer is impregnated and overlaid with the filled PTFE bearing lining.

The metal backing provides mechanical strength, while the bronze sinter layer provides a strong mechanical bond between the backing and the bearing lining. This construction promotes dimensional stability and improves thermal conductivity.

These polymer bearing linings, being predominantly PTFE, offer exceptionally low friction.

THERMOPLASTIC-BASED METAL-POLYMER MATERIALS: DX®, DX®10, DTS10, DS, HI-EX

DX®, DS and HI-EX have a similar structure to the PTFE-based materials described above; but with these products, the bearing lining consists of a filled thermoplastic extruded tape.

These materials are generally designed to operate with marginal lubrication. DX® and HI-EX are most commonly provided with a uniform pattern of indents in the bearing surface that act as grease reservoirs.

The incorporation of PTFE filler in DS enables this material to operate dry when required. Due to the inherent lower friction of this polymer blend, it is usually supplied without indents.

The high-performance engineering polymer found in HI-EX gives this material excellent temperature and chemical resistance combined with good load capacity and is particularly suited for operation under arduous conditions with oil lubrication.

Hydro Bearings


Combining the self-lubricating properties of PTFE with the strength and stability of a glass-fiber-filled epoxy resin backing, HPM bearings offer maintenance-free, environmentally friendly operation with no additional lubrication required. They have high static and dynamic load capacities, tolerate impact, shock and edge loading, and provide longer service life with their low friction and wear rate.

Suitable for rotating, oscillating and linear movements, the bearings are dimensionally stable with low water absorption, making them suitable for use in seawater. They also resist corrosion, weight 75% less than equivalent-size metallic bearings, and can be machined to required tolerances.

Engineered Plastics Bearings


EP SERIES, KA GLACETAL, MULTILUBE AND FLASH-CLICK
Our injection-moulded engineered plastics bearings provide excellent wear resistance and low friction in both dry and lubricated operating conditions over a wide range of applications. Consisting of nine different materials, the new EP Series of polymer materials is made of a variety of resins compounded with reinforcing fibers and solid lubricant. They exhibit excellent dimensional stability, low coefficients of friction, high compressive strength and creep resistance, low thermal expansion and good thermal conductivity.

We also manufacture acetal-based KA Glacetal thrust washers for light-duty applications, as well as our Multilube bearings available in various forms, which contain lubricants dispersed in the material.

FLASH-CLICKTM bearings are the industry´s first dual component double-flanged engineered plastics bearings which feature a special geometry for simple manual or automated installation without the need for a pilot or assembly tools.
