T H E D I F F E R E N C E The Standard Components with the Highest Standards™ JERGENS CLAMPING SWING CYLINDERS Precision machined for close tolerance between piston groove and pin. Better fit results in smoother motion and a more durable swing cylinder assembly. Free-floating pin design matches the shape of the groove. More contact area and less wear “keeps the pin in the pocket.” Heavy-duty, low-friction rod seal features “double-lip” sealing— virtually leak-free even under severe operating conditions. Plus, lubricant is retained in the cavity formed by secondary lip— increases performance and quiets operation. High-pressure, low-friction, bi-directional piston seal is easier to turn and reduces leaks. OTHER CLAMPING SWING CYLINDERS Less surface area between bearing and track combined with severe conditions within the clamp body result in deforming of the bearing and assembly breakdown. Ball bearings can “pop out” of the track—a common failure of traditional swing clamps—causing the piston to seize. Seals may be more prone to wear and “dry run.” Failure of traditional seals is the primary failure of swing cylinder clamps. Breakdown of traditional seals is the primary failure of swing cylinder clamps. Galled seals cause contaminants, accelerating breakdown and increasing downtime. V-grooves and Ball-bearing Engagement Internal piston is driven by a ball bearing that rolls in a rounded track on only two points. Less surface contact leads to more wear and reduced product life. Squared Tracks and Pin Engagement Internal piston is driven by a pin designed for close tolerance with squared track. Larger load-bearing surface results in a more durable assembly. VS.
