HC-3500-12 has a 4 in OD and is made to fit a 3 in bore cylinder.

Head cap size is determined based on the bending stress.

A static seal or o-ring is used in between the head cap and barrel (except welded construction).

The main function of the head cap is to enclose the pressure chamber at one end. The cap is connected to the cylinder body by means of welding, threading, bolts, or tie rod.

105mm 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.

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.

MCPO-12 has a 12 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.

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.
