1.1.7.3.3.Capacity and Series Designations (c)

Upright Translating Metric Ball Screw Actuator Models
Model Number 28501280228052810282028302860 Rating (kN) 102550100200300500 Inverted Translating Ball Screw Actuator Models Decrease the upright model number by 1, e.g. 2804, 50 kN inverted Metric actuator. Rotating Ball Screw Actuator Models Increase the upright model number by 1, e.g. 2806, 50 kN rotating Metric actuator. Optional Lead Metric Ball Screw Actuator Models Metric Ball Screw actuators have an increased lead option for the ball screw assembly (typically double the standard option). To specifythe optional lead add a "1" to the end of the model number, e.g. 28051, 50 kN upright optional lead Metric Ball Screw actuator.

1.1.7.3.4.Third Space Numerals (d)

The characters appearing in this space is to indicate raise in millimetres on all standard units, but not on specials. This space on specialactuators helps to identify to our Engineering Department the actual actuator model produced. The numerals do not indicate raise ortype of modification performed on special orders.

1.1.7.3.5.Suffix (e)

B -Indicates bellows boot required to protect lifting screw. G -Secondary guide for the lifting screw. L -Single-end worm shaft extension on left-hand side only. R -Single-end worm shaft extension or right-hand side only. 1 -Alternate gear ratio required. X -Supplied without bottom pipe, but with guide bushing. Note 1.All suffixes (e) that do not conflict with another may be used in series against one actuator unit.
