Product Details

•The RHD series combination type is designed for applications seeking the ultimate in compactness. Featuring an ultra-thin, hollow-flanged structure for the flexible wheel, this design reduces the axial length by approximately 50% compared to the RHSG series—making it ideal for demanding applications that require a sleek, space-efficient flat layout.

Features of the RHD Series
• Ultra-thin, hollow-structured design
• Compact and concise design
• High torque capacity
• High rigidity
• Zero backlash
• Excellent positioning and rotational accuracy
• Coaxial Input and Output
