Ergonomic nutrunners incorporate LED spotlight
Designed to maximise comfort and ease of use, even in hard-to-reach areas, Bosch Rexroth's new ErgoSpin ESM pistol-grip nutrunners feature lightweight yet robust construction and an integrated LED spotlight that brightly illuminates the working area. Activated by pressing the tool's start button, the spotlight can be programmed to operate for 1-99 seconds and can also, if necessary, be disabled.
These new nutrunners are available in versions with torque ranges of 2.4-12Nm and 5.0-25Nm. 12Nm models are offered with a choice of a 1/4-inch square output drive or a quick-change chuck. 25Nm models can be supplied with either a plain 3/8-inch square drive or a 3/8-inch square drive plus a Hirth tooth system for use with accessories such as central nut tightening jigs.
All of the nutrunners in the new ErgoSpin ESM range benefit from an ergonomic construction that helps to ensure high user acceptance and minimise operator fatigue, thereby boosting productivity. Further productivity gains are possible through the durable construction of the tools that incorporate non-contact angle and torque sensors. Furthermore, they are designed to operate for at least one million cycles at full load without requiring maintenance.
The new ErgoSpin ESM nutrunners are fully compatible with cables and controllers in the extensive Bosch Rexroth System 300 family of tightening products. They also offer the convenience of plug-and-run operation. This means that when a nutrunner is connected to a controller, it is automatically recognised and configured, so non-productive set-up time is virtually eliminated.
Tight control over tightening
Tightening systems incorporating the new nutrunners can be readily configured to provide, for example, full control over tightening rate and torque, and over the total angle through which the nut rotates during the tightening process. The functions of the buttons on the tool can also be configured to meet the user's exact requirements. In addition to this, System 300 controllers can capture and store data, so full traceability can be achieved.
As well as its new ErgoSpin ESM pistol-grip nutrunners, Bosch Rexroth offers an extensive range of handheld straight and angle tightening tools with torques up to 220Nm in standard configurations and even higher in custom versions. Also available are stationary tightening systems that use the same 300-series software as the handheld tools for easy programming and parameterisation.
To complement its tightening product family in fixing applications, Bosch Rexroth also supplies versatile pressfit systems that are particularly well suited for use in automated production lines. The flexibility of these systems is enhanced by the ability to control a wide range of setpoints, while integrated transducers make it easy to configure them to suit almost any type of workpiece.
