Rodless Cylinders TRAC-TROL®  with Linear Bearings
 		 <back to Table of Contents>

Trac-Trol® combines linear ball bearings in a trolley which runs on hardened and ground shafts.

FEATURES
  • Air or hydraulic service for smooth operation and precise control.
  • Nylon-covered, aircraft-type cable for extra long life.
  • Optional low cost rod & cable wipers.
  • Extremely small effective sealing area compared to band cylinders for longer working life and ideal for use in “dusty” applications.
  • Greater bearing surface for larger capacities.
  • Reed switches available.
  • Aluminum hardcoated tubes standard or optional steel tube (special plating available).
  • Pre-delivery testing and “break-in” to insure customer satisfaction.

LUBRICATION

Generally speaking TRAC-TROL® trolleys don’t need lubrication. To insure maximum life, all pneumatic cylinders should be supplied with filtered and lubricated air

 
LOADING

Many applications of the TRAC-TROL® cable cylinder involve mounting some of the weight off the side of the unit. To be certain the correct size TRAC-TROL® is used in your specific application use the following equations to compare the calculated load to the curves on the Load vs. Stroke graph which shows the maximum load allowed for a given stroke. Do not exceed the maximum load limit.
 
LOAD = Fs + Fp Where Fs = Reaction force due to side loads.
Fp = Reaction force due to push/pull loads.

 
DIMENSIONAL DATA
 
MODEL 15, 20, 20P, 25, 25P, 32, 40 and 50  NON-SUPPORTED

NOTE:  FOR MODEL 15 TRAC-TROL ®, REED SWITCH OPTION INCREASES OVERALL LENGTH BY 2".


NOTE: Dimension TT may be larger than dimension AA. Dimension Z is mounting hole location.
Dimensions in inches.
Tolerance on Overall Length is + 1/16"

 
MODEL 10 TRAC-TROL® SUPPORTED

MODEL 15, 20, 20P, 25, 25P, 32, 40 & 50   SUPPORTED


 
SUPPORT SPACING (All Other Models) — Determine the number of supports for given stroke length by subtracting “KK” from the stroke length, then divide by 24.
(Stroke - “KK”) ÷ 24 = number of supports
(Round to nearest whole number)
From the head mounting holes, the first support is located by the following:
Stroke + U - ((number of supports - 1) x 24) = Hole location of first support
                                2

Other supports are spaced 24" apart.

SUPPORT SPACING (Model TS10 only) — Determine the number of supports for given stroke length by subtracting “KK” from the stroke length, then divide by 12.
(Stroke - “KK”) ÷ 12 = number of supports
(Round to nearest whole number)
From the head mounting holes, the first support is located by the following:

Stroke + U - ((number of supports - 1) x 12) = Hole location of first support
                          2

Other supports are spaced 12" apart. 

 LOADING — MAXIMUM LOADS —
Horizontal Mounting
MODEL TS15 - 266 lbs. MODEL TS20 & 25 - 450 lbs.
MODEL TS20P, 25P, 32 & 40 - 750 lbs.

IMPORTANT! With inverted mounting, maximum load is one half the horizontal mounting
maximum load.


Many applications of the TRACTROL® cable cylinder involve mounting some of the weight off
the side of the unit. To be certain the correct size TRAC-TROL ® is used in your specific
application use the Fs + Fp equations to see if the calculated load falls beneath (under) the
maximum load limit. Do not exceed the maximum load limit.

TRAC-TROL Shock Absorber (A) Package

AVAILABLE ON TRAC-TROL ®
MODELS 10, 15, 20, 20P, 25, 25P, 32, 40 & 50
 
The internal cushions, standard on all GREENCO cylinders, are an effective
method to decelerate loads, and minimize harmful shock loading at the end of
each stroke.

In very high speed applications, cushions may be overloaded and shock
absorbers are necessary.

The GREENCO External Shock Absorber Package is a highly effective way to minimize
shock loading in a wide variety of applications (refer to chart). Additionally,
the package utilizes (2) two fully adjustable, mechanical stops to vary stroke
length as may be required by the application.

SHOCK PACKAGE CONSISTS OF: 2-shock absorbers, 2-shock mounting blocks, 2-
stop collars, 2-locknuts and 2-adjustable stops.

IMPORTANT - some applications may exceed shock design limits and could
require a special orifice or non-standard shock absorber. Consult Factory.

EXAMPLE - application requiring a TRAC-TROL ® model 15 with 100 PSI, and a payload
weight of 80 lbs. Referring to the sizing chart you would find 80 lbs.
on the vertical axis and move across until you intersect with model 15
line curve, from this intersection move toward the horizontal axis of the
chart which tells you the maximum velocity allowed at impact (5.3 fps).
Shock operating temperature 32O -150O F. At maximum loads cycle rates must be
limited to 30 hits per minute on model 10 and 17 hits per minute on models 15, 20,
25, 32, 40 and 50. Cycle rates increase with lower loads.

NOTE - Shock Package Adds to Cylinder O.A.L.
MODEL INCREASE IN O.A.L.
T10 ..............................................................................5.00"
T15, TS15 ....................................................................5.375"
T20, T25, TS20, TS25....................................................5.125"
T20P T25P, T32, T40, TS40,TS20P, TS25P, TS32 ..........6.06"
T50 ..............................................................................6.75"
