CD210G80/36-160Z1X/01HCUM1-1A Rexroth Hydraulic Cylinder

Product Overview

The CD210G80/36-160Z1X/01HCUM1-1A Hydraulic Oil Cylinder belongs to the heavy-duty Bosch Rexroth CD210 series (cross-compatible across CD210G, CD210B, CD210E, and CDL1MF4 mounting configurations). Manufactured strictly in compliance with ISO 6020/1 and DIN 24551 standards, this cylinder offers 100% direct drop-in interchangeability with original equipment. It features a high-strength precision-honed steel cylinder barrel, an induction-hardened hard-chrome-plated piston rod, and an advanced low-friction HCUM sealing package with adjustable end-position cushioning. Every cylinder undergoes 100% factory simulated load pressure testing at 210 bar prior to shipment, guaranteeing zero fluid bypass, precise displacement control, and long-term operating reliability under severe industrial conditions.

Key Technical Advantages

• 100% Drop-In ISO/DIN Interchangeability: Mounting flange dimensions, bolt circle diameters, rod threads, and extended dimensions match Rexroth OEM specifications precisely for seamless direct installation without machine modification.

• Precision-Honed Barrel & Chrome Rod: Super-finished cylinder barrel interior ($Ra \le 0.2\ \mu\text{m}$) combined with an induction-hardened, chrome-plated piston rod ($\ge 25\ \mu\text{m}$ coating thickness) prevents premature seal wear and mechanical scoring.

• Anti-Stick-Slip Low-Friction HCUM Sealing: Premium Polyurethane and PTFE guide ring systems minimize breakaway friction, eliminate low-speed stick-slip motion, and maintain zero internal leakage under 25 MPa pressure spikes.

• 100% Full-Load Factory Pressure Tested: Every cylinder is subjected to dynamic full-stroke cycling and static high-pressure holding tests at 210 bar to verify structural integrity and dampening performance prior to dispatch.

Application Areas

• Metallurgy & Steel Mills: Continuous casting cut-off actuators, rolling mill guide positioning, and heavy clamping systems.

• Industrial Presses & Heavy Machinery: Forging press auxiliary cylinders, metal shearing machinery, and high-pressure forming equipment.

• Plastics & Injection Molding: High-tonnage injection molding mold-clamping auxiliaries, core-pulling, and ejection circuits.

• Heavy Equipment & Power Units: Hydraulic power unit (HPU) positioning, gate opening systems, and high-pressure locking mechanisms.

Expert Maintenance Tips

• Prevent Side Loading: Ensure precise physical alignment between the cylinder rod axis and the driven load path during installation. Side loading causes uneven guide bushing wear and accelerates rod seal degradation.

• Bleed Trapped Air: Always bleed trapped air using the air-bleed ports or by cycling the cylinder back and forth 3-5 times under low pressure without load during initial setup to prevent aeration and unstable motion.

• Maintain Fluid Cleanliness: Maintain system oil cleanliness to ISO 4406 18/16/13 (or NAS 8) or cleaner. Ensure a high-efficiency pressure line filter is installed upstream to trap particulate contamination.
