RGP672 Low-Profile, Single-Acting, Load-Return Hydraulic Cylinder 1.75 in Stroke.

The Power Team RGP672 is a low-profile, single-acting, load-return hydraulic cylinder with an integral mechanical locking collar, rated for 67 tons capacity at 10,000 psi and a stroke of 1.75 inches. This “pancake” design provides high load support in confined spaces, with the locking collar intended to mechanically secure the load for extended periods after hydraulic pressure is released, improving safety and stability in temporary shoring, bridge jacking, and structural alignment tasks. The effective bearing area and short stroke configuration give a high stiffness-to-height ratio, while the swivel cap feature on the RGP series helps accommodate minor load misalignment and reduces localized edge stresses on the support surface.​

The RGP672 uses a single-acting configuration-hydraulic extension with spring-return optimizing circuit simplicity and minimizing ancillary components in field setups. Its flat, pancake form factor enables placement under equipment, structural members, or machinery where standard cylinders cannot fit. The locking collar provides positive load holding for maintenance, lifting, and jacking operations that require hands-free stability after actuator positioning. When paired with 10,000 psi pumps and standard Power Team couplers, the RGP672 offers controlled, repeatable performance in industrial, construction, and utility applications demanding high-output force with minimal overall height.

Related Products

  • Safe long-term load holding: The mechanical locking collar holds the load even if hydraulic pressure is lost, making it safer than relying purely on hydraulic seals.
  • Compact “pancake” profile: Very low height relative to diameter makes this series ideal for confined or restricted-clearance applications (e.g. under bridge bearings, piers, end caps)
  • Load alignment assistance: The swivel cap helps reduce side loads, improving life under offset loading.
  • Durable treatment: Power-Tech surface treatment helps protect against corrosion and wear in harsh environments.
  • Rapid collar engagement: Buttress threads help the locking collar engage reliably and quickly.
  • Visible safety feedback: The weep hole gives visual warning of overtravel or seal failure.
  • Range flexibility: The RGP series offers a broad tonnage spectrum (67–565 ton), giving options depending on lifting requirements.

⚠️ Considerations / Limitations

  • Single-acting only: Piston retraction is typically by return spring or external force; the lock collar must capture the load to hold it when hydraulic pressure is off.
  • Limited stroke: The strokes are relatively short which restricts how much movement or lift is possible without spacers or attachments.
  • Load alignment critical: Even with a swivel cap, off-center loading can accelerate wear—careful alignment is important.
  • Mechanical parts maintenance: The locking collar threads and interface zones are subject to wear and should be kept clean, lubricated, and inspected.
  • Tonnage range: 67  tons
  • Actuation style: Single-acting with mechanical locking collar
  • Stroke: 1.75 in
  • Effective area: 13.36 in
  • Oil capacity: 23.39 in
  • Operating pressure: 10,000 psi
  • Weight : 33.5 lb
  • Retracted (collapsed) height: 5.80 in
  • Extended height: 6.53 in
  • Outside diameter: 2.78 in
  • Material / surface treatment: Steel components with Power-Tech (nitrocarburization) surface treatment to resist corrosion and abrasion
  • Locking collar / load support:
    • Mechanical locking collar safely supports the load when hydraulic pressure is released, minimizing risk of load drop due to leakage.
    • Buttress thread design for collar strength and rapid engagement.
  • Swivel cap (load alignment): Patented 5° deep-swivel cap to help minimize off-center load effects.
  • Weep hole / overtravel indicator: A weep-hole is provided as a visual indicator in case piston overtravel occurs.
  • Port / coupler: One high-flow 3/8 in NPTF female half-coupler as standard for hydraulic fluid connection.
  • Carry eyelets: Included for ease of handling in many models.
  • Hydraulic system demands: Requires a hydraulic pump and hoses rated for the required pressure (up to 10,000 psi) for full capacity performance.
  • Sizing rule: Power Team recommends sizing to 80% of the maximum rated tonnage and stroke for safe, durable operation.
