Hydraulic Wear Rings

Fabricated from fine woven fabric and phenolic resins, this wear ring is strong yet light weight with an excellent wear rate.

Phenolic Material | 89 MM Nominal Inner Diameter | Wear Ring

Features

• Protection Against Wear
• Reduced Friction
• Extended Cylinder Life
• Operational Efficiency

Made from filled PTFE, these rings are suitable for light duty bearing service but are more often installed on the outboard ends of a piston to catch metal particles to protect the seal area.

Filled PTFE Material | 127 MM Nominal Inner Diameter | Wear Ring

Features

• Protection Against Wear
• Reduced Friction
• Extended Cylinder Life
• Operational Efficiency

WRFA bearings are manufactured of an extremely abrasion-resistant and low-friction POM-PTFE Bronze compound. Rings are split for easy installation and multiple rings may be arranged adjacent to each other with joints staggered. These are genuine Hunger® parts.

POM – PTFE/Bronze Material | 115 MM Nominal Inner Diameter | Wear Ring

Features

• Protection Against Wear
• Reduced Friction
• Extended Cylinder Life
• Operational Efficiency

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.
