SCS Powerbands®
SCS Sealing Products is pleased to introduce our new line of Powerband® tight tolerance premium wear-rings. Manufactured from a highly engineered blend of premium nylon, glass fiber, and PTFE, Powerbands® 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 Powerbands® are fully machined with cross-section tolerances of only ±0.001 in, chamfered corners, and scarf or angle-cut end gaps. Compared to standard tolerances of ±0.0025 in., 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. Powerbands® are currently available in our most popular wear-ring dimensions, as shown here. If you do not see your size or would like more information on this innovative product, please contact SCS.

SG - 'Seal Guard' Metallic Rod
Each Seal Guard Wiper consists of two flexible bronze rings which are held in place by a nitrile cushion ring. The cushion ring absorbs side loads and energizes the wiper to maintain close contact with the rod. Particularly suited for hostile environments, seal guard wipers shave off sand, grift, slag, flux, paint, moisture, chips and slivers. Seal Guard Wipers are long-lasting, self-adjusting, and offer low friction. Seal Guard Wipers can be installed in standard Hercules® Sealing Products “ST” or “D” Style grooves by increasing the “F” gland dimension to the “F” Throat Diameter shown.

Style ST wiper rings are precision molded from 90A durometer urethane. Flexible enough to easily snap into a groove yet tough enough to handle difficult rod wiping applications. 'V' tagged wipers are constructed of fluorocarbon.
Product Codes ending in SH are designed with a Slotted Heel. The slots in the heel allow excess hydraulic fluid to bypass the wiper, preventing wiper blowout.
