Concept of Modular range The CATR modular design concept makes it easy to interchange critical components such as motors, gears,
screws, attachments, etc. Custom built actuators are easily and cost efficiently built from standard parts. The CATR
range flexibility makes it suitable for an infinite number of applications.
Options: • AC or DC motors, 13 different alternatives • Ball or sliding screw • 3 screw pitches • 3 gear ratios • 7 standard stroke lengths up to 700 mm • Special stroke lengths up to 1500 mm. • Friction clutch gears • IP 44 or IP 65 • EMC filters (EN 50 081-1 and EN 55 022) • Range of front and rear attachments • Limit switches • Maintenance free
For easy selection three basic actuators forms the base for the Modular range:
• CATR 33 • CATR 33H • CATR 32B
ACME sliding screw, standard ACME sliding screw, high speed SKF Ball screw, for higher load or duty factors.

Duty factor • Design for intermittent operation • Permitted load related to duty factor, e.g. the higher the load, the less the permitted duty factor • Duty factor is defined as running time under load versus total cycle time
• The diagram shows load as function of duty cycle • For AC motors the capacitor must be selected with respect to the duty cycle and load. Required capacitor size is indicated in diagram.

Points to remember when using an actuator Alignment Make sure that the load is in line with the adjustment tube of the actuator. No radial load must be put on the actuator. Friction Clutch The friction clutch is not intended for use as a load limiter, but only for protection of the actuator and the mechanism to which the actuator is fitted. Environment The actuator should be protected against: • direct contact with water • rapid changes in temperature combined with high relative humidity • strongly corrosive environments Overload Actuators must not be overloaded. Exceeding maximum static loads involves a risk of buckling.
Temperatures The CATR can normally be used within a temperature range -20°C to +50°C. All performance data stated in the catalogue are only valid at 20°C. Lubrication A few drops of oil may be used on the adjustment tube if the actuator is used in a corrosive environments. Electric connections Make sure that the motor and limit switches are correctly connected and that the correct voltage is used. Continuous operation Actuators are intended for intermittent operation, but can operate continuously under special circumstances.
If incorrectly used an actuator can be unsafe. Consult SKF for application support.
