The Kyntronics Difference

Benefits of Electro-Mechanical Screw Type

• Use Power-on-Demand
• Large installed base – user familiarity
• Programmable and controllable
• Configurable with several Fieldbus options
• Integrated Motor options

Challenges of Electro-Mechanical Screw Type

• Failures from shock loads, side loads and end-stop crashes
• Metal-to metal wear reduces operating life creating reliability issues
• Follow the L10 rating chart (Figure 1) and need to be oversized to increase operating life
• Become expensive over 5,000lbs. rated force (see Figure 2) and over 36″ stroke length
• Do not offer integrated force measurement (must add expensive load cells)
• Rely on motor encoder feedback for position measurement that is affected by backlash
• Repair costs are expensive with long lead times
• Have limited Dynamic Ingress Protection (IP) ratings

Kyntronics Advantages

• Uses Power-on-Demand
• Absorbs shock loads, side loading and end-stop crashes without damage
• No metal-to-metal component wear
• Operating life is load-independent (Figure 1)
• Available with standard stroke lengths to 120″ without large cost premiums (See Figure 2)
• Available with rated force options from 100lbs. to 150,000 lbs.
• Incorporate an optional pressure transducer at the cylinder piston to measure force
• Directly measure the position at the rod end using a position sensor
• A “Total Solution” option (actuator, motor, drive, software) is available
• Actuators are field repairable

Benefits of Hydraulic System

• Can produce large forces at high speeds using high HP (KW) HPUs
• Robust operation, handles shock loads without issue
• Cost-effective for simple applications
• Compact cylinders – high force density
• Can provide higher Ingress Protection (IP) ratings

Challenges of Hydraulic System

• Hydraulic pump runs continuously at maximum pressure and speed wasting energy
• Require regular filter and oil changes – expensive and environmentally hazardous
• Violent transitions and vibration lead to inevitable leaks causing unplanned downtime and safety risks
• To precisely control position and force, expensive add-on components are required
• Do not offer integrated force measurement (must add expensive load cells)
• Contamination results in downtime and excessive maintenance by a dwindling cohort of trained hydraulic technicians

Kyntronics Advantages

• Actuator is completely sealed, no hoses or threaded connections minimize leak risk
• Use Power-on-Demand to save energy, very efficient operation
• Lower cost of ownership (Table 1)
• Does not require a Hydraulic Power Unit – saves space and is much quieter
• Precisely controls position and force
• Requires minimal maintenance
• A “Total Solution” option (actuator, motor, drive, software) is available
• Provides simple Fieldbus connectivity
• Can easily add more actuators to a machine

Benefits of Pneumatic System

• Cost-effective (assuming compressed air infrastructure exists)
• Provide rapid motion
• Simple to install and maintain
• Clean operation
• Compact footprint

Challenges of Pneumatic System

• Air leaks – inefficient
• Limited to lower rated-force applications
• Difficult to control – require expensive add-on components
• Pressure drops – inconsistent operation
• Air contamination
• Insufficient lubrication

Kyntronics Advantages

• Actuator is completely sealed, no hoses or threaded connections minimize leak risk
• Use Power-on-Demand to save energy, very efficient operation
• Load zone is throughout the full stroke length
• Quiet operation (no compressor)
• Precisely controls position and force
• Requires minimal maintenance
• Versatile actuator configurations
• A “Total Solution” option (actuator, motor, drive, software) is available
• Provides simple Fieldbus Connectivity

Benefits of Air-Over-Oil System

• Fast motion coupled with a larger force
• Cost effective
• Uses existing compressed air infrastructure
• Quiet operation
• No continuously running motor

Challenges of Air-Over-Oil System

• Challenging to control – not versatile
• Limited “load zone”
• Many leak points – air and hydraulic connections and hoses
• Difficult to size
• Energy inefficient
• Contamination resulting in downtime and high maintenance

Kyntronics Advantages

• Actuator is totally sealed, no hoses or threaded connections minimizes leak risk
• Use Power-on-Demand to save energy, very efficient operation
• Load zone is throughout the full stroke length
• Quiet operation (no compressor)
• Precisely controls position and force
• Requires minimal maintenance
