Hercules® Sealing Products is pleased to introduce our new line of PowerbandTM tight tolerance premium wearrings. Manufactured from a highly engineered blend of premium nylon, glass fiber, and PTFE, PowerbandsTM offer a high strength wear-ring for all cylinder applications, including those with minimal lubrication. And, with a Coefficient of Friction nearly 50% lower than our standard product, your cylinders will run smoother and more efficiently than ever. All PowerbandsTM are fully machined with cross-section tolerances of only ±0.001”, chamfered corners, and scarf or angle-cut end gaps. Compared to standard tolerances of ±0.0025”, this tightened tolerance improves the alignment and concentric operation of cylinder rods and pistons. The fully machined chamfered corners will better accommodate cylinder housing grooves, further improving piston and rod alignment. Lastly, the scarf-cut end gap reduces the loss of bearing support that may occur during cylinder side-loading. When combined, these features reduce the tolerance stack-up within the components of the cylinder. As a result, your cylinders will operate more consistently and be capable of operating at higher pressures and higher side loads than with standard wear-ring products. Furthermore, with this improved cylinder operation, your seals will last longer and the life of your cylinder will be extended. PowerbandsTM are currently available in our most popular wear-ring dimensions.

2-1/2 Rod Gland Kits

The PS1400 seals offer low friction and high strength in a compact double-acting piston seal design. The PTFE seal ring, combined with a rubber energizer, assures positive contact with the dynamic surface. The PS1400 is designed to fit ANSI/B93.32-1973 groove standards. Piston diameter “I” dimensions are given for pistons without wear rings.

15% Glass Filled PTFE Material | 1.983 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

Used as a companion to our “B” lip configured Style 850 u-seal, Style 855 PRC rings convert a uni-directional u-seal into a bi-directional seal.

95A Durometer | Urethane Material | 4 1/4 in Nominal Inner Diameter | 3/8 in Cross Section | Ring

Totally interchangeable with Style PS1400 PTFE piston seals, Style PS1500 piston seals are molded from tough 60 Shore D durometer polyurethane. During the molding process, a .002” thick band of molybdenum disulfide is molded into the outside diameter of the seal ring for reduced friction. PS1500 piston seals are easily stretched over the piston and recover rapidly with the elimination of the “cold flow” characteristics found in PTFE seals. Piston diameter “I” dimensions are given for pistons without wear rings.
