This medium duty wiper is molded in nitrile rubber.

Nitrile Material | 38 MM Inner Diameter | Wiper

Molded from tough polyurethane material, these seals offer high resistance to wear and abrasion. Energized with a four-lobed ring, they have greatly increased low pressure performance.

Urethane Material | 50 MM Nominal Inner Diameter | U-Seal

This wear ring is molded from glass reinforced nylon. This style is highly recommended because of their wear rate and non-scoring properties and their ability to ingest metal chips.

Nylon Material | 80 MM Nominal Inner Diameter | Wear Ring

Features

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

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

Phenolic Material | 95 MM Nominal Inner Diameter | Wear Ring

Features

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

Grade 8 nylon insert lock nut. The thread size is
1 in – 14 UNF and the nominal hex is
1.625 in.

Grade 8 lock nuts have a nylon insert in the nut that allows the nut to grab the fastener. This keeps the nut from backing off due to vibration.

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.

Asymmetric rod seal designed with precision trimmed sealing lips to provide a dry sealing solution in light and medium-duty applications. The Hallite 605 is molded in Hythane® 181, Hallite’s high-performance polyurethane, for easy installation and excellent low temperature performance. The twin lip design helps solve difficult rod sealing problems by providing lower friction, increased stability, and high, dynamic lip force, while preventing air penetration from outside the cylinder. Designed to have interference in the seal housing groove and has a secondary lip. The secondary sealing lip located behind the primary sealing lip improves stability of the seal in the gland. The inner dynamic lip is shorter and more robust to improve sealing and compression set characteristics over conventional, symmetrical U-seals.

The seal can be considered for use in heavy-duty applications when used with a suitable full depth back-up ring. The sealing lips are precision trimmed at an angle to give optimal rod sealing performance.
