description

  • DX prelubricated bearings effectively fill the gap between fully lubricated bearings and dry bearings.They are referred to as "prelubricated" because they require only a trace of lubricant to operate satisfactorily and will, therefore, run for very long periods by drawing only upon the lubricant introduced on initial assembly. DX is a steel-backed material from which bearings, thrust washers, and other shapes can be made. The DX material can be sized in place by boring, reaming, etc. This ability to resize the DX is of particular value in the control of initial starting clearance and the correction of misalignment. The wall thickness of DX bearings is held to close limits so that machining should be unnecessary for most applications. DX is recommended for conditions of intermittent operation or boundary lubrication, and for situations in which lubricant cannot be supplied continuously or repeatedly. The time during which a DX bearing will operate without further lubrication will depend on operating conditions.

applications

  • Oscillating applications
  • Full rotating service
  • Thrust washers
  • Agricultural equipment
  • Off-highway, truck, and automotive
  • Handling and lifting equipment
  • Hydraulics
  • Machine tool building industry
  • Engineering and general applications

features

  • Steel backing is the key to the exceptional strength
  • thin, compact design
  • excellent heat dissipation
  • and dimensional and structural rigidity of DX bearings. This rugged, copper-plated steel backing also provides a good interference fit in metallic hous
  • Porous bronze innerstructure: This comprises a nominal 0.010" (0.25 mm) layer of carefully sized, bearing quality bronze powder sintered onto the steel backing. This porous bronze innerlayer is impregnated with the acetal resin and is securely sintered to
  • Loads - P: Dynamic pressures up to 20,000 psi (140 N/mm²) ensuring high load carrying capacity and resistance to shock loading.
  • Speeds – V: Speeds up to 500 ft/min (2.5 m/s) with grease lubrication
  • PVs to 80,000 psi-ft/min (2.8 N/mm² x m/s) for continuous operation
  • Temperatures from -40 °F to 210 °F (-40 °C to 100 °C) continuous and up to 260 °F (125 °C) for short periods.
  • Ideal for all types of rotating, oscillating, and sliding motion, and both raidal and thrust loading.
  • Typically grease lubricated. Can also be lubricated with oil, other lubricants, and can be used in the presence of may industrial liquids. DX is not recommended for dry applications
  • instead we recommend DU.
  • Frictional properties The dynamic coefficient of friction is very low, between 0.01 and 0.1, depending on speed, load, and lubrication conditions. The coefficient of static friction of DX bearings ranges from about 0.015 to 0.15.

caution

  • Aluminum housings can be used for pressures up to 3,000 psi
  • Steel housings must be used for operating pressures above 3,000 psi
