SB (ROD WIPER) HYDRAULIC

product

SB is a single action wiper ensuring that foreign particles do not penetrate into the hydraulic systems, avoiding wear and damage to all the internal components including seals.

PRODUCT ADVANTAGES:

  • Superior wiping performance
  • Axially open, easy-construction groove
  • Wide range of dimensions
  • secure seating, press fitting into the housing
  • Space-saving construction.

APPLICATION:

Light and medium duty construction machinery, forklift-trucks, agricultural machinery,support cylinders and standard cylinders. 


INSTALLATION:

Wiper is pressed into axially open housings. Special equipment should be used during this process.  It is very importent that assembly tools must be soft material and have no sharp edges. Before installation the wiper must be oiled with system oil.

NOTE: SB wipers are single action and can be used with combination of all rod sealing elements. SB wipers can be produced on request in steel/fpm for special applications thatrequire hight temperatures.

MATERIAL: STEEL / NBR 90 SH
