CABLE-TYPE
TRAC-TROL guides on
close-tolerance metal bearings, completely separated from
piston and cable seals. When loaded, there is still no
effect on sealing mechanism. |
BAND-TYPE
Load transmitted directly to
piston and could effect sealing detrimentally. |
|
TRAC-TROL has superior sealing mechanism which allows hydraulic
service for very smooth, long-life performance. |
Hydraulic service not possible.
Must seal entire length of extrusion. |
|
TRAC-TROL seals through two nylon covered aircraft type,
pre-stressed, steel cables held to +.004 on the O.D., many times
stronger than load carried. |
Must
seal entire length of tube, exposing much more surface to air
loss and contamination problems. |
|
TRAC-TROL has low-cost cable and rod wipers available for
extremely contaminated areas. |
Not
available. Real problems in contaminated areas. |
|
TRAC-TROL offers 7 bore sizes in 2 styles, total of 16 models. |
Only
4 sizes available, one company.
Two sizes from another. |
