IMPULSE WRENCHES Specified torque range The specified torque range is measured in the laboratory under standard conditions. Therefore these torque figures are only to be used as a guidline. The actual torque range depends on a variety of working conditions, eg: air pressure, joint hardness, used accessory. Adjustment of torque level of the tool. The torque ranges are specified at a dynamic air pressure of 0.6 MPa, lower air pressure will result in lower torque. Please take note that these impulse wrenches are developed for a dynamic air pressure of 0.63 MPa maximum. Soft joint example Hard...

IMPULSE WRENCHES IMPULSE WRENCHES POKA YOKE+ SYSTEM YLa-JQ SERIES Lightweight YLa-JQ series Type Square / Bolt Hex drive capacity mm Inlet thread functioning principle The system is controlled by measuring the air pressure at the inlet side of the air motor. This air pressure varies from free running to impulsing. By this measured air pressure the controller detects contact of the bolt head (point 2). Upon contact, the adjustable timer gives the shut-off signal (point 3). Adjustability of the timer takes care of adoption to either hard or soft joints. Similar, the controller detects double...

IMPULSE WRENCHES IMPULSE WRENCHES Double chamber air motor Pistol models YX-SERIES: NON SHUT-OFF DIMENSIONS Inlet thread The Y-40SA is a straight model, all other types are pistol models. * Torque specifications All specified torques are measured on the YOKOTA testers, series YET, at a dynamic airpressure of 0.63MPa. The YOKOTA testers have a static transducer, the specified torques are therefore to be used as a guidance only. In general the torque range will be lower in case of using lower airpressure, extension bars, torx or hexagon inset sockets, soft joints, etc. Square / Bolt Hex drive...

YOKOTA Japan developed the system wrench with torque control more than 25 years ago, in order to tighten and shut-off the impulse wrench at the target torque with the features as insufficient or over torque, error detection, bolt counting, group control, production line management, data saving etc. Due to increased market demands for accuracy and error detection, YOKOTA integrated the additional angle monitoring function. By controlling the angle during the tightening process, all possible errors can be detected. CONTROL UNIT FOR THE TKa SERIE High accuracy Product liability is essential to...

The YOKOTA electric system wrenches with integrated torque transducer and angle sensor offer a large reduction of energy consumption, a high degree of accuracy and fantastic work efficiency. Electric drive: • Reduction of energy consumption  Lean and Green. • No need for pneumatic installation with compressor, air piping, hose and solenoid valves. • No need for lubrication of the tool. Good for the working environment, especially near paint shops. • Due to the newly developed outer rotor servo motor and the composite body, the YOKOTA system e-wrench has lightest weight in its class. HYBRID...

BATTERY SYSTEM E-WRENCH BATTERY SYSTEM E-WRENCH YOKOTA impulse wrenches are powerful, very accurate and most important, have no kick-back. The YOKOTA system e-wrench has a built-in torque transducer and angle-encoder on the main shaft and is wireless connected to a controller. Each controller can connect with up to 4 independently operating battery system e-wrenches. The YOKOTA battery system e-wrench is the perfect solution for applications where cables or hoses are disruptive, but you still need to have all data checked, controlled and documented. System configuration • Possible to...
