Bimba EF Cylinders
The Bimba EF Series is a compact, aluminum-extruded body air cylinder

designed for international machine requirements.
The body is anodized in a special PTFE-impregnation process that provides superior wear charac-
teristics. With its streamlined look, low cost and low-profile switch, it is an excellent choice for
space-saving machine design.

Extruded Flat Repair Kits

For bore sizes of 12, 16, and 20, each Extruded Flat Basic Kit includes the
appropriate rod guide, rod seal, piston seals, cylinder, body seals, and Repair Kit
instructions. For larger bore sizes (25mm and up), a rod bushing is included K-B-EF-__
instead of the rod guide. Please note that EF repair kits will work on EF2 K-B-EFD-__
cylinders. K-B-EF-__-V
To order, please provide the correct bore code in the kit part number blank. K-B-EFD-__-V
Specialty seals are designated by their suffix option.

How to Order
The Model Number for the EF2 cylinder consists of three alphanumeric clusters. These designate type, bore size
and stroke length, and options. Please refer to the charts below for an example of Model Number EFT-3225-3M.
This is a 32mm bore, double acting, guided cylinder with metric threads and ports, 25mm stroke, threaded
front/rear mounting holes, and magnetic position sensing.
TYPE BORE SIZE mm (inch) ** STROKE LENGTH ***
EFT - Double Acting, Non-rotating 12mm - (1/2") 40mm - (1-1/2") See table - page 2.59

1
with option V, standard bumper material is supplied. Operating tem-
perature remains -10° to 70°C (15° to 160°F).
2
When option E is specified, user interface threads are designated
U.S. customary (inch). This includes ports, rod threads and threaded
mounting options (as applicable).
3
When magnetic position sensing is specified with option V, operating
temperature remains -10° to 70°C (15° to 160°F). This combination is
recommended when fluoroelastomer is specified for compatibility.
4
Automatically includes bumpers, so stroke is reduced by 3mm.
5
Available stroke lengths starting at 10mm.
6
In EFDT models, extra extension dimension is added to both tooling
plate and rod ends.
Please note that throughout all catalog charts, metric measurements are shown first and U.S. customary units (inches) are in parentheses.
**NOTE: Numbers in parentheses are the equivalent bore size in inches and listed FOR REFERENCE ONLY. DO NOT use for model
designation.
***When stroke length exceeds 30mm, a threaded mounting option should be considered. Mounting bolts that span the entire cylinder
length may not be readily available.

* The stroke adder for EFP cylinders is equal to 2 times the stroke length of A plus the stroke length of B. For example, an EFP-2550/25-3EMV would
have a total combined stroke length of 125mm. All total combined stroke lengths are rounded to the nearest 5mm.

Bimba Metric Twin Bore Series Cylinders
The Bimba Twin Bore Cylinder is a small cross-section, double-bore cylinder that provides highly accurate linear
Square Flat-1
motion. The cylinder incorporates extra long piston rod bearings, resulting in high radial load capacity. Single and
Flat-1/
double end rod units are available in both Delrin® and ball bushing styles. The highly precise Air Table incorporates a
rigid linear rail with recirculating ball bearings.

Each TB and TBD repair kit includes the appropriate number cup seals, rod K2-B-TB-__-V
wiper seals, rod seals, and rod guides. The TBA kits include the bumper in K2-B-TBD-__
addition to the seals. K2-B-TBD-__-V
To order, please insert the bore code after the model designation for the K2-B-TB-__-X
desired repair kit. Suffix after bore code indicates seal and ball bushing options. K2-B-TB-__-VX
For Twin Bore cylinders prior to May, 2003, use the same part number except K2-B-TBD-__-X

See the following section on how to size the shock absorber to a specific application. Shock
absorbers within a given bore size have the same dimensions regardless of dampening strength.
How to Size The Shock Absorber
EFP/EFQ
“The shock absorber is pre selected for size by the bore diameter of the cylinder. However, the “dampening
strength must be selected to choose the proper shock absorber. To calculate the necessary shock, the following
values must be known.
Cylinber Bore Diameter d(mm)

Mounting Orientation (horizontal or vertical)
Et (Total Energy) equals the sum of Ek (Kinetic Energy) and Ew (Work Energy). Note the “Work Energy calculation
varies with mounting orientation, Ewh for horizontal and Ewv for”vertical applications.
Ek = ( (W/2) + k1 ) x v2 [Nm]
NPA/LPA
Ewh = k2 x p x k3 [Nm]
Ewv = ((k2 x p) + W + k1) x k3 [Nm]
Et = Ek + Ew [Nm]

EtC = Et x c [Nm / hr]

Et and EtC must not exceed maximum values listed below. Dampening must be chosen from graphs on
