Manual Rotary Tables & Turntables Overview
This document provides detailed specifications and features of Velmex's manual rotary tables and turntables. It includes information on different models, their design, and applications.
Rotary Tables
Rotary tables utilize a worm and gear drive design with a central rotating ball bearing. Two main series are discussed:
- Series A4800: Available in three models with gear ratios of 18:1, 36:1, and 72:1. Features include a hollow spindle, 360° scale, and a graduated knob. These tables can be motorized with a NEMA 23 motor.
- Model A5990TS: Features a 90:1 gear ratio, hollow spindle, and standard black anodized finish. It can be motorized with a NEMA 17 motor.
Both series offer options for minimizing gear backlash and can be adapted for use with UniSlide systems using specific adapter plates.
Specifications:
- Central Horizontal Load Capacity: 200 lbs for A4800, 50 lbs for A5990TS
- Central Vertical Load Capacity: 25 lbs for A4800, 5 lbs for A5990TS
- Accuracy: 100 arc-second
Turntables
Turntables differ from rotary tables as they can be spun freely by hand and feature a 12° range of fine position adjustment. They are suitable for mounting and rotating test specimens, cameras, and sensors.
Key features include:
- Engraved 360° scale with 6-minute resolution
- Maximum horizontal load capacity of 200 pounds
- Spring-loaded tangent screw drive for fine adjustments
Turntables cannot be motor-driven and are not recommended for tensile or vertical loads greater than 1 lb.
Models:
- Model A2505TS: Mounts on A15 Series 3” slider and A25 or B25 2 1/2” sliders.
- Model A4007TS: Mounts on all A40 or B40 sliders and A/B 60 sliders.
Both models have specific mounting configurations and adapter compatibility.
