Heavy Duty Forestry Grapple Cylinder - Welded Double Acting 160-350 Bar
APEX Hydraulic offers custom-engineered heavy-duty grapple cylinders designed specifically for forestry and logging equipment. These double-acting welded hydraulic cylinders operate at working pressures from 160 to 350 bar and can be configured with bore diameters from 50 to 250 mm and strokes up to 1500 mm. Built to withstand shock-loading and abrasive environments, they feature high-strength alloy steel rods with hard-chrome plating, heavy-duty rod wipers, and optional spherical bearings for angular misalignment in grapple linkages.
Key Selling Points
- Shock-load resistant design: Engineered for repeated gripping and opening under impact loads, with high-strength rod eyes and base eyes.
- Heavy-duty welded construction: Suitable for mobile attachments and forestry equipment, ensuring durability in tough conditions.
- Optional spherical bearings: Accommodate limited angular movement in grapple linkages, reducing stress on pins.
- Protected piston rod: Induction-hardened or corrosion-resistant rod surface treatments available for severe environments.
- Recessed or guarded ports: Reduce risk of impact damage during operation.
- Full testing: Every cylinder undergoes dimensional inspection, pressure testing, leakage testing, and full-stroke functional testing before shipment.
