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.
