TMMA pullers series: hydraulic SKF EasyPull
|
|
Quick
and effortless bearing dismounting
|
|
|
|
The
hydraulic versions of the EasyPull, TMMA 75H and
TMMA 100H, combine the user friendliness of the
|
|
mechanical EasyPull with the effortless force generation provided by
integrated hydraulic spindles. The
|
|
pullers are protected
from overload by safety valves built in their hydraulic spindles.
|
|
|
|
Ready-to-use, integrated hydraulic cylinder, pump and
puller thus it is assembly-free and it is not necessary to purchase
separate parts
|
|
Safety valve prevents spindles and pullers
from being overloaded if excessive force is applied
|
|
The spring-loaded centre point on the hydraulic
spindle allows easy centering of the puller on the shaft without damaging the
shaft
|
|
The TMMA 100H has a maximum withdrawal
force of 100 kN (11.2 ton US) and a long stroke of
80mm (3.1 in), which facilitates most dismounting jobs in just one operation
|
|
For dismounting jobs requiring less force, SKF offers
a 75 kN (8.4 ton US) version, the Hydraulic EasyPull TMMA 75H with a maximum stroke of 75 mm (3 in)
|
|
Supplied with extension pieces and one
nosepiece
|
|
Application
|
|
The
TMMA series of hydraulic pullers is available in two sizes to provide a
withdrawal force of either 75 or
|
|
100
kN (8.4 or 11.2 ton US). They are designed to
extract mechanical components by gripping onto the
|
|
Circumference
of the component, a so-called external pull. The width of grip varies from 52
mm (2.0 in) to
|
|
250
mm (9.8 in) depending on type.
