Project Description

Series AW14: Heavy-Duty, Double-Acting Wiper

The AW14 Series Heavy-Duty, Double-Acting wiper is one of the most popular mill-duty wipers in the steel industry. It includes a reinforced PTFE-filled scraper ring and two energizing O-rings. The design incorporates a wiping lip to prevent contamination from entering the cylinder and an inner sealing lip to remove any oil film from the rod as it cycles. The O-rings individually energize the two wiper lips. In most applications, a pressure relief port between the wiper and the rod seal is recommended.


The AW14 Series Heavy-Duty Double-Acting Wiper prevents contamination ingress in harsh environments, while maintaining low friction.It consists of a custom-blended PTFE that provides ultra-low friction and high-speed performance with minimal wear. The standard compound is PTFE with Bronze filler. The temperature range of the wiper can be increased by selecting an FPM energizer in place of the standard NBR energizer.

Typical applications include:

  • Steel and aluminum mills

  • Positive and negative bending cylinder

  • Work roll balance cylinders

  • Pullback/return cylinders

  • Traverse cylinders

  • Injection Molding Machines
