Double Acting Hydraulic Cylinder with Clevis Both Ends

A clevis both ends cylinder (also called eye-to-eye, double clevis, or twin clevis) has a pin-mount boss at both the cap (blind) end and the rod end of the cylinder. Both bosses have the same pin bore diameter. The cylinder installs with exactly two clevis pins — one through each boss into the corresponding bracket. No separate rod-eye, spherical joint, or rod-end adapter is required. This is the fastest-installing metric cylinder configuration and the most common for European agricultural and industrial equipment where both bracket geometries are fixed and the centre-to-centre distance between mounting pins is predetermined. See our KWB cap-end clevis series if you need a spherical rod-eye at the rod end for angular misalignment accommodation.

Yes for all ISO 6020-2 dimensions. KWC pin bore ØJ, boss OD ØK, boss length, and body OD follow the same ISO 6020-2 table as Bosch Rexroth CDH1, Parker metric eye-to-eye, and Bucher LBH series cylinders of the same bore. This means KWC cylinders accept the same clevis pins, the same bracket geometry, and the same centre-to-centre spacing as the OEM products they replace. The bore-specific dimensions on the KWC bore card (ØJ, ØK) match the CDH1 and Parker specification sheets directly. Send the OEM part number to sales@hydraulic-cylinders.net for confirmed cross-reference before ordering.

Choose KWC when both bracket mounting points are fixed pins at a predetermined centre-to-centre distance, and there is no angular misalignment at the rod end during stroke. KWC installs faster (two pins only) and has no separate parts to source. Choose KWB when the rod-end bracket requires angular misalignment accommodation — the KWB rod-end thread accepts a spherical rod-eye (ISO 6982) that allows the rod to follow a curved path during stroke. If you are replacing an existing cylinder, match the configuration to what is already installed — if the original had a spherical eye at the rod end, use KWB; if it had a pin through a fixed clevis at both ends, use KWC.

The pin bore is H7 tolerance at both ends. The same pin diameter fits both ends of any given bore size. Nominal pin bore by bore: 32mm and 40mm bore = ØJ 16.25mm, 50mm bore = 20.25mm, 60mm and 63mm and 70mm bore = 25.25mm, 80mm bore = 30.25mm, 90mm and 100mm bore = 40.25mm. The nominal pin size to use is one step below the H7 bore nominal — a 25.25mm H7 bore accepts a 25mm pin. Pins should be case-hardened steel (minimum 55 HRC surface) per ISO 8675. Pins are not included with the cylinder — specify if you require matched pins or material certification when ordering.

The 60mm bore KWC series offers rod diameters of 30mm, 35mm, and 40mm within the same 73mm body OD. The three options cover different column load and pull force requirements: a 30mm rod suits short-stroke clamping where column load is low; a 35mm rod is the standard for mid-range stroke; and a 40mm rod provides maximum pull force and column load resistance for long-stroke applications. All three use the same 25.25mm pin bore at both ends, so the bracket geometry is identical regardless of rod choice. Specify rod diameter when requesting a quote.

Yes. Custom strokes are available from 500 pcs minimum per bore-and-stroke combination. The barrel length is cut to produce the exact stroke specified — no other dimensions change, including the clevis boss positions. Specify the stroke in millimetres when requesting a quote; we confirm feasibility and pricing within 24 hours. For strokes exceeding 1000mm, enquire with bore, stroke, load, and mounting details — longer stroke cylinders may require reinforced barrel specifications or modified boss L2 (rod-end boss) length to maintain structural integrity at full extension.

Provide: bore diameter (32–100mm), rod diameter (for multi-rod bore sizes: 40mm = 20 or 25mm, 50mm = 25 or 30mm, 60mm = 30, 35, or 40mm, 70mm = 35 or 40mm, 80mm = 40 or 50mm, 100mm = 50 or 60mm), stroke length, port position if non-standard, seal type (standard PU/NBR or FKM for high temperature or synthetic fluid), and quantity. For OEM replacement, include the Bosch Rexroth CDH1, Parker, or Bucher part number and we cross-reference before confirming. For OEM programmes, provide annual volume forecast and delivery schedule.
