The Dynamic Duo of the STH Series: STHVL7 and STHEL7 Rotary Index Tables
The STH Series rotary index tables continue to deliver exceptional precision, rigidity, and integration flexibility for mid-range rotary indexing applications. Two proven configurations—the STHVL7 (inline) and STHEL7 (right-angle)—offer OEMs reliable solutions for demanding rotary positioning environments.
Built on the same high-performance STH platform, both models provide the accuracy, load capacity, and motor-mounting versatility required in modern automation systems
Core STH Series Features
Both the STHVL7 and STHEL7 share a common foundation engineered for precision automation:
85 mm hollow bore for cable, tube, or mechanical routing
Heavy-duty cross-roller bearing for stable load support
Backlash as low as 2 arc-min
Indexing accuracy to ±60 arc-sec
4:1 output gear for smooth, repeatable motion
Optimized motor mounting system with active centering
Designed for mid-range rotary indexing applications
Supports high tilting moment loads (200 Nm) and radial loads (5000 N)
STHVL7: Inline Performance for Clean, Straight-Through Power Transmission
The STHVL7 integrates the STH rotary index table with the VRL-070 inline planetary gearbox, delivering a compact, axial motor alignment that supports straightforward machine layouts.
Key advantages of the inline configuration include:
VRL-070 inline planetary input
Slim, compact footprint
Simplified motor orientation and wiring
Ideal for applications with available axial space
Clean and efficient mechanical layout
STHEL7: Right-Angle Flexibility for Space-Constrained Designs
The STHEL7 pairs the STH rotary index table with the EVL-070 right-angle planetary gearbox, offering a 90-degree motor orientation for applications where space efficiency is critical.
Key advantages of the right-angle configuration include:
EVL-070 right-angle planetary input
90-degree motor orientation for tighter installations
90-degree motor orientation for tighter installations
Greater flexibility in overall system layout
Ideal for space-constrained environments
Built for Precision Automation Applications
The STH Series provides the accuracy, rigidity, and integration flexibility required for reliable rotary positioning across a range of industries, including packaging, automation, robotics, and assembly.
With two proven configurations built on a shared high-performance platform, the STHVL7 and STHEL7 give machine designers the flexibility to choose the right solution without compromising precision or performance.
