Product Details

The Bosch Rexroth MSK050B-0300-NN-M1-UG1-NNNN is a highly dynamic IndraDyn S servomotor specifically optimized for vertical and suspended loads.

Identified by material number (MNR) R911309705, this Size 050 motor uniquely integrates an electrically released holding brake (UG1), making it the premier choice for Z-axis automation where clamping the load during power loss is critical. It delivers a solid 3 Nm of standstill torque and reaches maximum speeds of 4,300 RPM. Coupled with an advanced multiturn absolute encoder (128 signal periods), it ensures exact position retention and maximum safety in your most demanding material transfer and assembly operations.

100% Original & Authentic Integrated Holding Brake Expert Technical Support 12-Month Warranty

Key Technical Highlights

✓ Integrated Holding Brake (1): Essential for vertical applications. The electrically released brake automatically engages during power failures, safely clamping tools or loads to prevent catastrophic drops.
✓ Absolute Multiturn Precision (M1): Features a high-resolution absolute encoder with 128 signal periods. It instantly recognizes its exact position upon startup without requiring time-consuming homing cycles.
✓ Plain Shaft for Friction Fit (G): The plain output shaft guarantees a zero-backlash connection when paired with friction-clamping couplings, maximizing point-to-point accuracy.
✓ Consistent 3 Nm Output: Provides a highly reliable 3 Nm standstill torque within a naturally cooled (self-cooling) housing, minimizing maintenance overhead.

Common Technical Questions

Q: Why is a Rexroth servo motor with holding brake necessary for my application?

A: The integrated brake (indicated by '1' in UG1) is crucial for vertical or inclined load-bearing axes. It operates on a fail-safe principle: if the machine loses power or faults out, the brake clamps down instantly, preventing heavy tooling or suspended materials from crashing down.

Q: What is the benefit of the Rexroth absolute encoder 128 signal periods (M1)?

A: The 'M1' encoder tracks the motor's position precisely across multiple rotations. The high resolution of 128 signal periods ensures incredibly smooth speed control, while the absolute memory lets the machine restart production immediately after an e-stop without searching for a zero point.

Q: Is this a direct Bosch Rexroth R911309705 replacement?

A: Yes, this is the exact, genuine replacement for MNR R911309705. Because it involves a built-in brake, it is vital to match this number exactly to ensure your machine's safety circuitry functions correctly.
