The advantages of a UT pulley with internal bearings, are the same as for a drum motor.
The bearings are well protected by our IP66 sealing system, and as the shafts are non-rotating when the pulleys is turning, it means that the pulley can offer a higher performance that a pulley with external bearings (Radial load = T1 + T2).
We produce all UT pulleys in the same dimensions as our drum motors.
