Frequently Asked Questions
What’s the engineering purpose of the 70 Nm holding brake on MKD112C-058-KG3-BN for vertical Z-axes or index tables?
The brake supplies static torque to hold load when torque-producing current is removed to prevent drift on power-off or emergency stop. It supports safer standstill for suspended masses and rotary fixtures until the drive re-engages.
How does IP65 plus a sealed plain shaft on MKD112C-058-KG3-BN influence ingress, lubrication, and coupling life?
The shaft seal and IP65 enclosure limit particulate and fluid ingress at the bearing/coupling interface for helping preserve grease films and fit tolerances. It reduces abrasive wear and contamination-driven fretting during cyclic duty.
What does the 38 Nm continuous torque at standstill on MKD112C-058-KG3-BN imply for tension-regulated unwind/rewind or dwell-heavy indexers?
It sustains defined torque at zero speed for enabling stable tension or holding force without overheating when sized to RMS currents. It addresses prolonged standstill duty and corresponding current/thermal dimensioning for MKD112 frames.
What mounting precision is expected from the 130 mm centering diameter on MKD112C-058-KG3-BN, and is the flange pattern DIN 42928 compliant?
The 130 mm pilot governs concentricity/runout to align the rotor with machine mechanics. It simplifies accurate, repeatable mounting and retrofit scenarios.
How does the output-connector orientation on MKD112C-058-KG3-BN influence EMI and routing in constrained cabinets?
The defined connector exit options and cable-set geometry let designers route away from sensitive IO and minimize loop area for EMI management. It outlines permissible output directions for MKD112 frames to aid enclosure layout.

Internal Product Review
The Bosch Rexroth Indramat’s MKD112C-058-KG3-BN couples a sealed plain shaft and 70 Nm brake with resolver-based absolute detection for accurate angular motion. It requires a rated 400 V supply to operated and possess insulation of category F. This unit is IP65 protected from external intrudes and it delivers 38 Nm at standstill with size 112/130 mm centering. Its output connector simplifies cabinet wiring to fit into applications like printing/packaging, food processing and handling automation.
