Manually-Operated Velmex Rotary Tables
Velmex Rotating Tables deliver precise, continuous rotating motion for scanning, assembly, testing and production. They are a convenient, accurate method of quickly positioning or rotating a payload. The tables are offered in two configurations – Rotary Tables and Turntables.
The Rotary Tables use a rugged worm and gear drive design with a central rotating ball bearing to turn the payload. They are available either manual or motorized. The larger Rotary Table can support payloads up to 200 lbs. (90.7 kg) and the smaller can handle payloads up to 50 lbs. (22.6 kg.)
Velmex Rotary Table Features
Rotating Table Applications
Typical applications for Velmex Rotary Tables include mounting and rotation of test specimens, cameras, transducers, sensors, mirrors and other components. The tables can also be used to tilt and pan.
Manually-Operated Rotating Tables
Rotary Tables – All Velmex Rotary Tables rotate smoothly and easily around a single axis. They can be mounted either horizontally or vertically.
Part number information for each style can be found under Specifications at the end of the page.
A48 Series – Three models with gear ratios of 18:1, 36:1 and 72:1. The B4800 Series has a load capacity up to 200 lbs. (90.7 kg.) horizontally and 25 lbs. (11.3 kg.) vertically. (The payload it can support vertically depends on the gear ratio. The lower the ratio, the less weight it can support.)
Revolution time at 600 rpm ranges from 1.8 to 7.2 seconds, respectively. The series features a hollow spindle or clear aperture in the center. Aluminum finish is standard.
A59 Series – One model with a 90:1 gear ratio. The smaller A5900 can handle 50 lbs. (22.6 kg.) horizontally and 5 lbs. (2.3 kg.) vertically. The series features a hollow spindle or clear aperture in the center and comes in a standard black anodized finish.
Rotating Table Specifications
Factors such as size of the motor, size of the payload, in operation time, mounting direction/plane, etc. effect the actual capability of any assembly. Please contact Velmex Application Engineers to configure a system that will meet your exact requirements.

Options/Accessories for Manual Velmex Rotary Tables
Several options can be added to both the Rotary Tables and Turntables to make them more versatile and configurable with other Velmex products.
Rotating Table Adapter Plates –to mount Velmex Rotary Tables to other Velmex Assemblies either in horizontal or vertical positions. For more specifics and to see the plates and brackets in use on a Velmex stage visit the Rotary Tables Adapters page.
MSPP-3 Adapter Plate – Used to mount Rotary Table (A48 or B48 Series) to BiSlide.
|XZ Brackets – allow Rotary Tables to be positioned vertically. They can mount two Rotary Tables at right angles. The brackets can also be used as the base and support to mount other Velmex products or the payload on the Rotary Table vertically.|
A4001XZ-R Adapter Bracket – For mounting the A4800TS or B4800TS Rotary Tables.
Platform shelf – A right angled bracket designed to be used with UniSlide® Elevating Tables. However, they also can be used with vertically mounted Rotary Tables to support a payload. The shelf can be inverted depending on the motion required.
Thumbscrew Lock (-TL) – An easy method to lock the table utilizing a simple thumbscrew.
Alternative Knob – – An knob with a crank for faster rotation is available for the A5990TS. Standard configuration is the knob only.
Magnetic Home Switch – A magnetic reed home switch sets and returns the carriage to home (starting) position.
Limit Switches – Using two zero-reference (home) switches on a Rotary Table creates limits that restrict travel to a specific degree arc.
Finishes – The A48 Series of Rotary Tables has a brushed aluminum finish. Optional finishes are available at an additional charge and include:
• Black Anodizing, additional colors also available (pictured)

Velmex also offers motorized Rotary Tables. Examples of other Velmex products can be found on the Examples page or in the Examples section for each product.
Many questions can be answered by reviewing the "Features", "Model / Series", "Specifications", "Options / Accessories" and "Technical Documentation" sections for each product line. Additional FAQs about product comparisons, product construction, purchasing and shipping can be found on the company FAQ page.
Do Velmex Rotary Tables need lubrication and how often?
Normally, the worm/worm gear drive of Velmex rotary tables do not need any servicing. However, under severe conditions replenishing the lubricant will prolong the life of the gears. A small amount of Lubriplate can be placed in the access hole. See the user guide that came with your Rotary Table for instructions.
Do Velmex Rotary Tables have an open aperture?
Yes, both models of Rotary Tables have a hollow spindle or open aperture in the center for optical applications. The manually-operated Velmex Turntable does not.
Can Velmex Rotary Tables be used in conjunction with other stages?
Yes, Rotary Tables can be and are frequently combined with other slides to achieve a particular motion or positioning. Which stage used in conjunction with the Rotary Table will determine which adapter plate or bracket might be required.
