Uryu UL Series Oil-Pulse Tools
The Uryu UL Series has the same features as the Uryu ULT series, such as intensified sealing and roller blade. The oil pulse unit is the one piece construction in which liner casing, liner and front liner plate are all in one piece, to reduce the weight. The torque output can easily be adjusted by turning Torque Adjuster through the plug hole or the anvil hole without dismantling the tool.
As a measure of the new sealing, a partition on the anvil and SU-Ring (PAT.P) are adopted. The partition walls off the direct high pressure from the liner front plate. And SU-Ring intensifies the gripping area of the liner front plate to avoid its rotation together with the anvil. It brings you a long durability.
Newly adopted Roller Blades (Driving Blade with Roller Pin) (PAT.P) reduce the friction inside the pulse unit and improve the energy efficiency. Roller Blades also reduce the frictional wear of driving blades, which helps you to save the maintenance cost of driving blades.
9-blade “Double-Chamber” motor creates super productivity on any joint rate. It provides efficiently slow free speed, compared with the same sized “Single-Chamber” motor. Bolt seating is performed very smoothly, and the torque spike caused by the spinning of the anvil is eliminated to the minimum level on the hard joint. Prevailing torque type joint is also overcome with the optimum cycle time by the effective motor power.
