The mechanical TMMA series consists of 3 (TMMA 60, TMMA 80 and TMMA 120) pullers differing in size and withdrawal force.
Sturdy design allows dismounting
of components even in the tightest
application in a safe manner
The unique red rings spring-operated
opening mechanism allows the EasyPull to
be placed behind the component with one
movement of the hands
Self-locking arms help prevent the risk of
puller slipping under load
Double hexagonal heads allow easier
application of withdrawal force
Self-centring capability and nosepiece help to avoid damage to shaft Efficient use oftimedue to quick dismounting
Available in three sizes with a withdrawal force of 60, 80 or 120 kN (6.7, 9.0 or 13.5 ton US), enabling easy selection Hydraulic force industrial generators available as an accessory for the 80 and 120 kN versions
Hydraulic 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 centring of the puller on the shaft without damaging the shaft
