TRAC-TROL® Guided Cylinder For Linear Motion Control

Trac-Trol ® is a guided cylinder with linear motion control and is ideal when an application requires a load bearing system to be self guided and self supported. As the piston is pushed in one direction, the load is pulled in the opposite direction within the length of the cylinder. Effective piston area is greater that conventional rod cylinders and there is equal force in both directions.

Guided linear actuators, also called guided cable cylinders, can be configured to a variety of positions and ports along with a wide selection of accessories including Automatic Tensioners, Reed Switches, Shock Absorbers, Stainless Steel Guide Rods, Rulon Bearings and More.

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.
  • Optional reed switch package available, click here for additional info.
  • 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

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.

DIMENSIONAL DATA

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

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 -150° 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.
