Product Description
Water Stop Cylinder Mill Type Cylinder
CDH1 MT4 Mill-Type Cylinder, 100/70×1300mm, Trunnion Mount, Double-Acting, Rexroth Compatible
Product Overview
CDH1 MT4 mill-type cylinder featuring 100mm bore, 70mm rod, and 1300mm stroke. Double-acting design with trunnion mount on the head end. The MT4 mount positions the pivot point near the rod side, allowing the body to swing while the rod end remains stationary—ideal for articulating arms and pivoting linkages.
Construction & Materials
- Barrel: 27SiMn seamless honed tube with roller-burnished internal finish
- Rod: CK45 or 40Cr material, induction hardened with 25-35 micron hard chrome plating
- Surface hardness: HV 850-950
- Gland assembly: Bolted design with 12.9 grade hex bolts for easy rebuilding
- Trunnion pins: Brass material pressed into MT4 mounting block for natural bearing surface
Features & Performance
- Gland housing with side hex port (G1/2 or M22×1.5 hose fitting compatible)
- Service side access with top port on cap end for blind-side flow
- Adjustable cushioning screws at both ends for precise deceleration control
- Rod end: Spherical bearing eye with grease nipple and self-aligning capability
- Replaceable hardened steel bearing requiring no machining
Sealing System
PTFE step-cut primary seal with NBR energizer on piston, PU U-cup buffer, and double lip wiper on rod. Standard Parker/Merkel profile geometry with off-the-shelf seal kit compatibility.
Testing & Certification
Hydrostatic testing at 35MPa for 5 minutes, followed by full-stroke cycling at 25MPa with cushioning verification. Mounting dimensions fully compatible with Rexroth CDH1 MT4 factory specifications.
Applications
Articulated boom cylinders, swing arm actuators, pivoting press linkages, steel mill tilt cylinders, construction equipment—any application requiring cylinder body pivoting during operation.
