Expect the same rugged reliability, speed, flexibility and options you always count on from Rapid-Air.
- Fast job changeover.
- Compact and simple to install.
- High production rates.
Computer controlled feed rolls grip and move material rapidly and precisely into a stamping press or automation operation.
Selecting the right Servo model.
Primary considerations in selecting a servo feed should be material thickness, width, and press speed. Once the model series has been selected, review the description in the Model Selection Guide chart for features associated with that model. Questions? Contact sales@rapidair.com.
We also offer Servo Stagger Feeds, Tandem Servo Feeds, and Servo/Straightener Combos… see charts below.

| Model | Description |
| MiniServo – 115 VAC MS2, MS4 & MS8 (.040 max. material thickness, 8” wide maximum, 250 S.P.M.)* | Economical programmable roll feed, 99 job storage, feed advisor, wide range of accessories. Ideal for shops making transition from air feeds. MiniServo feeds are economical enough to mount and leave on the die, saves set-up time. Compact size makes the Mini ideal for automation equipment. |
| 100D Series – 115 VAC (.085 max. material thickness, 18” wide maximum, 400 S.P.M.)* | Programmable roll feed, 99 job storage, feed advisor, feed complete signal, Data Instruments and Link Press control compatible, batch count, adjustable speed, acceleration/deceleration. Wide range of accessories, higher speed than MS Series with the convenience of 115 VAC. |
| 100T Series – 230 VAC (.105 max. material thickness, 18” wide maximum, 450 S.P.M.)* | Similar to 100D Series but with more capacity, speed and torque. See table. |
| 200T Series – 230 VAC (.105 max. material thickness, 24” wide maximum, 500 S.P.M.)* | This Servo feed group has everything the 100T Series has plus larger feed roll diameter. Higher capacity and speed. Air regulated feed roll pressure and standard air pilot release. |
| 200TX Series – 230 VAC (.125 max. material thickness, 24” wide maximum, 500 S.P.M.)* | Similar to 200T Series but with more capacity. See table. |

All the features of a 100T Series plus the extra power to straighten .080 thick C.R.S. (.060 thick at 12” max. width, commercial low carbon steel). The KBX may be used as a Servo Feed alone by merely raising the straightening rolls. Patent. |
| KBXP104S and 108S – 230 VAC | Similar to KBX100S Series but with air pilot release. Patent. |
Note: KBX Series provide floor space saving by eliminating the material loop between feed and straightener.
* Speeds (S.P.M.) are based on 1.0” progression and 180º feed angle.
Model STF6
SERVO DRIVE STAGGER FEED STF4, STF6, STF8
Produces the most parts from the least amount of material.
Rapid-Air’s STF Series Servo Drive Stagger Feed maximizes material usage by pre-programming the optimum pattern to reduce coil material waste. Enhances even the most simple die by feeding it diagonally, side-to-side, or in any pattern.
- The programmability allows use of common or uncommon stock widths. Uncommon stock widths may be purchased at a lower cost and maximized by using our servo drive stagger feed.
- Any pattern, staggered or column, can be created for round or non-round parts to maximize material usage, staggered or column.
- The STF Series is a dual servo drive working in harmony with the die to provide fast, accurate moves.
- Feeds coil material up to 8” (203mm) wide x .085” (2.15mm) thick. Shuttle travel 8.5” (216mm). 8.0 usable travel.
- Incorporates our reliable, high performance Rapid-Air servo which offers quick changeover and speed, unlike time-consuming mechanical models.
- User-friendly Rapid-Air controls.
- In-house programming capabilities no one else can offer.
- Pilot release is included. Just add valve.
- 250 strokes per minute, with or without pilot release.
- Low maintenance.

Example of Tandem Servo Feed
TANDEM SERVO FEEDS
Ideal for feeding thin or very flexible materials.
A Rapid-Air Tandem Servo Feed is recommended when feeding thin or very flexible material into a die. Two synchronized feeds prevent buckling by maintaining tension on the stock using a special program. A Primary Servo Feed is placed at the entrance to the die and a Secondary Servo Feed is placed at the exit. You can later convert to two standard feeds, if desired, by a simple addition of a keypad and a standard program for the slave unit.
