The primary function of a wiper is to keep contaminants such as dirt dust and moisture from entering the fluid power system Contaminants can cause significant damage to the rod cylinder wall seals valves and other components One of the primary causes of premature seal and component failure in a fluid power system is contamination

ROD WIPERS or EXCLUSION SEALS prevent the drawing of foreign matter into the cylinder on the ingoing stroke Abrasive particles adhering to the rod will cause rapid wear to the Gland Seal if they are not effectively excluded The SERIES 50 MEDIUM DUTY ROD WIPER has proven itself over many years of service in a variety of industrial and farm equipment applications

Wipers are primarily designed to stop contaminants from entering a cylinder on the rod however they can also act as a secondary rod seal If contaminants were allowed to enter the cylinder it could lead to damage of your rod and or the damage of other sealing components A properly selected wiper could help reduce the need for unscheduled maintenance and even increase

2013 11 06 nbsp 0183 32 Style HW Rod Wipers Designed for medium duty applications and can provide both wiping and sealing action in one component in low pressure systems The external lip scrapes foreign matters from the rod and the other lips act as an effective pressure seal in low pressure applications This wiper can also be used as a secondary seal to trap

Wiper seals maintain sealing contact to the piston rod when the equipment is stationary static no reciprocating motion of rod and in use dynamic reciprocating rod whereas the tolerance for the rod diameter d is determined by the rod seal Without a wiper seal the retracting piston rod could transport contaminants into the cylinder

is a metric standard series rod wiper seal utilizing two 1 78 mm O ring energizers to fit a 14 0 mm rod The O ring material is N 70 Nitrile and the Wiper Seal Material is Carbon Fiber filled PTFE EMB 0140 A 08 Series Standard single o ring energizer Gland Cross Section See Table 3 Page 5 Size Code 0140 14 0 mm 248 x 10 O Ring Material See Table 2 Page 3 Wiper Seal

These wipers have an interior lip that sits in the rod edging keeping the wiper in the same positon relative to the rod Snap In wiper seals are designed without any metal component and are east to install without any special equipment The Snap In wiper varies from the metal clad wiper in that it fits in a gland in the cylinder

Rod wipers scrape dirt dust and moisture from the rod preventing contamination inside your cylinder Rod seals maintain the pressure inside cylinders and prevent fluid from leaking out Wear rings guide the rod and piston to prevent uneven wear and optimize seal performance Head seals are a more reliable alternative to the standard O ring backup ring combination
