  • S: Standard straight cylinder structure

  • 16: Stroke 160 mm

Core Specifications

Rated working pressure: 70 MPa (industrial high-pressure standard)
Port: NPT3/8, standard equipped with B-6JG hydraulic quick coupling
Min. closed height: 285 mm
Outer cylinder diameter: 125 mm; inner cylinder diameter: 95 mm
Required oil volume: 1135 mL
Net weight: approx. 24 kg
Material: Cylinder barrel & piston → SCM435 alloy steel (heat treated); piston rod → hard chrome plated
Protection: Equipped with wiper seal, suitable for industrial environments
Allowable lateral load: 1/20 of rated capacity (eccentric side loading strictly prohibited)
Matching pump: Compatible with Osaka Jack manual / electric hydraulic power units.

Structure & Features

  • Single-acting design: Extended by hydraulic pressure, automatic retraction by built-in heavy-duty spring, no reverse hydraulic pressure required.

  • Mounting threads reserved on bottom and side of cylinder barrel for fixed installation.

  • Compact and low-profile structure, suitable for lifting in narrow spaces, bridge & steel structure installation, heavy equipment maintenance.

  • Inverted installation, over-travel and over-pressure operation are strictly prohibited.

    Recommended working oil temperature: -5 ~ 45℃.

Selection & Operation Guidelines

Applications: Hydraulic lifting, equipment alignment, steel structure jacking, mold closing, etc.
Avoid continuous full-pressure operation and frequent impact loading.
Slow oil return operation to prevent violent rebound.
Custom anti-corrosion coating or stainless steel version is required for underwater / highly corrosive environments.
Hoses and couplings must withstand pressure above 70 MPa; regularly inspect seals and pipeline aging.
Maintenance: Regularly replace clean hydraulic oil; replace worn wiper seals in time; prevent scratches on piston rod.
