IDWR (ROD WEARRING 506)

product

IDWR 506 is a rod guide ring designed to be used in heavy dutyhydraulic.

PRODUCT ADVANTAGES

  • Low friction coefficient
  • Superior load cushioning effect
  • Better dimension stability at elevated temperatures
  • Easy installation
  • Wide range of dimensions
  • Safely usage in heavy and medium duty applications

APPLICATION:

Mobile hydraulics ,  mining industry , excavators , hydraulic presses , heavy duty cylinders.

INSTALLATION:

IDWR 506 is easily assembled into the housing by hand. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the guide ring must be oiled with system oil.

ATTENTION: The guidance must be placed where it is in direct contact with the media. IDWR is not suitable for dry working conditions. Surface contact pressure value would decrease due to temperature rise

MATERIAL: POLYESTER RESIN + PTFE
