Purchasing FAQ (selected)

• Q: How does RP52 compare with RP48? A: RP52 increases radial load capacity (200 N → 300 N), axial load (100 N → 200 N), rated torque (20 N·m → 30 N·m) and momentary shock torque (60 N·m → 90 N·m).
• Q: What is the output shaft diameter and keyway availability? A: Standard 12 mm solid shaft. Keyway, D-shaft or custom machining available per drawing for higher transmitted torque.
• Q: Is RP52 suitable for AGV platforms? A: Yes. 300 N radial capacity and 90 N·m peak torque make it suitable for heavy AGV wheel loads and impact events.
