Product Details:

REXROTH 060880048 is a servo tightening spindle from Bosch Rexroth legacy nutrunner system, equipped with resolver analog feedback and quick-change chuck interface. It delivers stable medium torque output with excellent continuous running performance, designed for repetitive bolt fastening tasks on automotive assembly lines. This legacy spindle model is discontinued by the manufacturer, and most available stock on the market are refurbished spare units for old production equipment maintenance.

This tightening spindle transmits resolver angle and speed signals to matched Rexroth tightening controller for closed-loop torque and angle supervision. The resolver feedback structure features strong vibration resistance and dust immunity, suitable for harsh workshop environments. It supports multiple tightening strategies including torque control with angle monitoring, and homing operation is required after power restart to establish rotation reference. Separate power and feedback terminal layout reduces electromagnetic noise interference inside industrial electrical cabinets with inverters and switching modules.

This variant is non-brake integrated spindle design, suitable for rotary multi-station fastening fixtures, powertrain assembly stations and household appliance bolt joining lines where static locking is handled by external fixture mechanism. The quick-change chuck allows operators to swap different sockets and adapts for mixed-model production, shortening product changeover time. The internal motor winding uses Class F insulation material and integrates thermal sensor for real-time temperature monitoring to avoid overheating damage during long-duration cyclic fastening operation. The spindle housing reaches IP54 protection grade to resist workshop dust and incidental liquid splashing. Optimized internal transmission design suppresses torque ripple greatly, maintaining consistent tightening precision for safety-critical bolt joints.

It supports torque control, angle monitoring and multi-step tightening sequences, and all tightening parameters can be configured via Rexroth tightening software. Compact spindle body can be installed inside narrow rotary indexers and limited automation space. Every finished spindle passes factory validation before shipment, including resolver signal calibration, torque repeatability test, insulation resistance inspection and vibration endurance test to guarantee stable performance in multi-shift automated fastening production lines.

It is widely deployed on automotive engine and transmission assembly stations, new energy battery module fastening lines, metal component assembly fixtures and small packaging bolt locking automation cells. Typical application axes include rotary tightening units, multi-spindle fastening modules, angle-controlled bolt driving stations and mixed-model assembly fastening platforms. Automation integrators select this Rexroth spindle variant for its robust resolver feedback, dependable medium torque output and seamless compatibility with Rexroth tightening control units.
