RC-308, 30 Ton Capacity,209mm Stroke, Single-Acting Spring-Retraction Hydraulic Cylinders

Series: RC | Product Line: Industrial Tools

• Advanced Surface Treatment for Superior Durability
  The cylinder body, piston, and stop ring undergo gas nitriding + post-oxidation, resulting in exceptional wear resistance, self-lubricating properties, and corrosion resistance. This advanced metallurgical treatment ensures long-term performance even under harsh operating conditions.

• Enhanced Corrosion Protection & High Visibility
  The external surface of the cylinder is finished with high-quality paint over a blackened (oxidized) coating, providing optimal corrosion protection and high visual identification – ideal for job sites where equipment recognition and rust prevention are critical.

• Reinforced Nylon Thread Protector
  A heavy-duty nylon external thread protector safeguards the cylinder’s outer ring threads from impact, debris, and damage, preserving thread integrity for repeated installations.

• High-Strength Lifting Eye – Heavy Tonnage Models
  Large-tonnage cylinders come equipped with a G80 grade lifting eye, certified for high-strength lifting and safe handling during transport and positioning.

• Hidden Vent Port – Faster, Smoother Retraction
  An integrated concealed vent hole allows rapid and stable spring return, eliminating trapped air and ensuring smooth, consistent retraction cycles.

• Polyurethane Seals – Longer Life, Better Performance
  Premium polyurethane seals offer outstanding sealing efficiency, high abrasion resistance, and extended service life – even under frequent cycling and high-pressure operation.

• Piston Wiper Seal – Reduced Contamination Risk
  Equipped with a dedicated piston wiper (dust seal) that minimizes ingress of dirt, dust, and moisture, significantly extending hydraulic cylinder service life.

• Ready-to-Install Interfaces
  Pre-machined external ring threads, piston threads, and base mounting holes enable quick and simple connection to accessories and mounting fixtures – no custom machining required.

• Flexible Mounting – Any Position, Any Direction
  The RC Series cylinders can be used in all mounting orientations and positions (vertical, horizontal, or angled), offering maximum application versatility.

• Standard Quick-Connect Coupler & Dust Cap
  Every cylinder is supplied as standard with a CEJN quick-connect coupler plus a protective dust cap, enabling fast, leak-free connection to hydraulic power sources.
