Parback® backup ring with a curved cross-section.

Parbaks are contoured on one face to minimize distortion of the o-ring when under pressure. Parbaks should be installed with the contoured face against the o-ring, but reversal does no harm.

90A Durometer | Buna-N Rubber Material | 3 1/4 in Nominal Inner Diameter | 1/8 in Cross Section | Backup Ring

Features

• Excellent extrusion resistance
• Easily stretched for installation
• Lubrication is enhanced by rubber which absorbs system fluid and does not plate out on rubbing surfaces

Hytrel backup ring with a flat cross-section.

Molded of 55D Durometer Hytrel, these back-up rings provide excellent extrusion resistance and tolerance to fluids such as phosphate esters, hydraulic oil and water. Stretched for installation, they return quickly to their original size for easy installation.

55D Durometer | Hytrel Material | 2 1/4 in Nominal Inner Diameter | 0.11 in Cross Section | Backup Ring

Features

• Improved extrusion resistance compared to standard FKM or NBR backups
• Can be stretched over larger diameters and will return quickly to their original size
• High strength and abrasion resistance
• Wide temperature range
• Chemical resistance
• Low friction
• Easy installation

ALHT8375X8000 has a 0.1875 in wall thickness. The ID is 8 in and the OD is 8.375 in. The material is 6063-T832 Aluminum.

Seamless extruded and cold-drawn. Hard coated on the ID which gives the aluminum tube a tough, abrasive-resitant surface.

6063-T832 Aluminum is used for pneumatic cylinder applications requiring very good corrosion resistance and/or light weight. Can also be used for low-pressure oil cylinders (250 psi or less).

• No machining required on the ID
• Seamless extruded and cold-drawn
• Hard coated interior
• Corrosion resistance
• Good weldability

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.

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.

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.

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.

25mm induction hardened chrome shafting.

The base material is 1045/1050 Carbon Steel with 0.0005 in (0.0127mm minimum)-thick chrome plating and a case depth of 0.05 in (1.27 mm).

Induction Hardened Chrome is typically used in abrasive envrionments where the cylinder is exposed to rocks or heavy debris. Also used to machine clevis pins.

• Greater strength
• Better resistance to mechanical damage

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.

MCPO-55 has a 55 mm diameter with Standard Chrome. The base material is 1045 Carbon Steel with a yield strength of 75,000 psi.

ASTM A108 is the most commonly used and economical grade of shafting for hydraulic cylinder components, blower shafts, and mandrels.

• Extremely smooth surface finish
• Excellent wear and corrosion resistance
• Good strength and impact properties
• Good machinability
• Reasonable weldability
• Fair response to normal heat treating and induction hardening practices

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.

.750 – 16 3000 PSI ORB PORTS #8

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.

60 Shore D Durometer | Polyurethane Material | 2.106 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
