Rubber Material | 1 in Nominal Inner Diameter | Wiper

Utilizing a sturdy metal case, these wipers are molded from the same high performance urethane used in our Heavy Duty U-seals. Built for severe service, these wipers are capable of surviving hostile environments.

92A Durometer | Urethane Material | 2 in Nominal Inner Diameter

Features

• Used in Heavy Duty U-seals
• Capable of surviving hostile environments
• Molded from the high performance urethane

Molded in a tough urethane, this seal employs an additional lip near the heel. The twin lip design provides stability, friction-reducing lube retention, and some contaminant resistance. VME – Secondary lip is further from heel than standard MRTU. NOTE: E = European Urethane.

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.

The PS1800 provides low friction, high strength piston sealing. The PS1800 also provides double-acting piston sealing in a compact design that meets the requirements of ANSI/B93-32-1973. Piston diameter “I” dimensions are given for pistons without wear rings.

15% Glass Filled PTFE Material | 1 11/16 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

Cast Iron Rod Clevis Mount with a 0.4375 in – 20 TPI threaded end and a 0.5 in pin hole.

Clevis mounts help maintain alignment and protect the cylinder from side load. Mounts attach to threaded stud ends, pivot holes, or bolt holes on the cylinder. Can be used with hydraulic cylinders with standard bore sizes.

Style ST-XL wipers are molded from premium urethane and are direct replacements for Style “ST” or “D” wipers. The outside diameter of the ring has a crush lip providing extra interference in the groove. A bead on the shoulder stops contaminates from entering through the groove. The inside diameter is ribbed to prevent pressure traps between the wiper and rod seal.

94A Durometer | Urethane Material | 1 1/8 in Nominal Inner Diameter

Features

• Crush lip to provide extra interference
• Bead on the shoulder to keep contaminants out
• Ribbed ID to prevent pressure traps

HT-9250X8000 has a wall thickness of 0.625 in. The ID is 8 in and the OD is 9.25 in. The material is DOM 1026 Carbon Steel and has been stress-relieved and annealed.

Full mill lengths will be cut to lengths between 12 ft and 19 ft long. Packages longer than 44 inches may have additional freight charges.

Style 850 u-seals offer excellent resistance to extrusion and abrasion. The round cross-section expander offers energized sealing from zero to 5,000 psi.
