How to choose Wipers

Points to check when selecting, with the values for this product (O-Ring Integrated PTFE/TPU Rod Wiper (A02/A05/A11/A12 Series)).

  1. 1. Select a size that matches the rod diameter

    This product: Applicable rod diameter d 50~600 mm

    Wiper dimensions are determined by the applicable rod diameter d, and listed products cover a range of 6 to 600 mm. If the inner diameter does not match the rod, insufficient scraping allows contaminants to enter, while excessive tightening causes wear and heat generation. Check the actual rod outer diameter and tolerance before selecting.

  2. 2. Match the housing groove dimensions and standards

    This product: Housing groove width 1~3 mm

    Wipers are designed to suit the shape of the housing groove in which they are installed. Confirm the housing groove width (1 to 3 mm for listed products) and which housing type of standards such as ISO 6195 the wiper is compatible with. When replacing parts in existing equipment, measure the actual groove dimensions before selecting.

  3. 3. Check installation space by overall height

    Overall wiper height directly affects the axial installation space, and listed products range from 7 to 16 mm. Confirm that the wiper fits within the cylinder head design space and its arrangement with the rod seal and guide. Designs with greater overall height often provide more allowance for the lip and retaining section.

  4. 4. Select a material suited to the fluid and environment

    PU offers excellent abrasion resistance and is widely used in environments with heavy mud or dust. NBR is well known for its compatibility with hydraulic oils. PTFE combined with an O-ring suits applications where friction and stick-slip (catching motion) need to be reduced. Choose according to the type of hydraulic oil and whether the application is for water hydraulics.

  5. 5. Confirm the operating temperature range

    Rubber and resin wiper materials degrade or harden at high temperatures and lose elasticity at low temperatures, which reduces scraping performance. For outdoor cold-region use or machines running high-temperature hydraulic oil, confirm that both ambient and oil temperatures fall within the operating temperature range.

  6. 6. Choose single-acting or double-acting and the sliding conditions

    Consider a double-acting type when you do not want residual oil film carried outward, or when combining with a PTFE rod seal. In environments where mud or ice adheres, designs that remove adhered foreign matter at the front stage are also used. Also confirm that the maximum sliding speed (1 to 10 m/s for listed products) exceeds the rod speed.
