The RBS style rod buffer seals are a rectangular urethane buffer ring designed to absorb pressure fluctuations thereby protecting the primary rod seal. Some sizes include a radial and axial slot, which faces the pressure, to relieve back pressure between the primary and buffer seal. This simple design is commonly found on older construction equipment. -
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.

This seal, molded from high grade polyester with 5% glass fiber and 5% PTFE, may retrofit the PS1800 seals, considering all dimensions are comparable. This seal material, with a high degree of 'memory', stretches over the piston and snaps in the groove for immediate assembly. These seals also feature low friction and high abrasion and extrusion resistance which helps to eliminate assembly damage. Piston diameter 'F' dimensions are given for pistons without wear rings.

Constructed of a rubber seal lip with a rubberized fabric heel, these seals feature a poly-acetal bearing ring or a poly-acetal anti-extrusion ring. These seals offer excellent sealing ability and high pressure capability. Commonly are used with the SR retention rings. -
Style PU seals are molded from high quality urethane and designed specifically for piston applications. -
The Style TP-L seal is a zero drift piston seal for bi-directional pressure applications. The locking anti-extrusion rings provide for an easier installation. It is designed to retrofit O-Ring and standard T-seal grooves. The 70 shore A NBR is designed specifically for performance in compression type dynamic seals. Other features include a net molded dynamic sealing surface and backup chamfers.
