Rotary Positioning Stages

November 15, 2017

Lintech’s Rotary Positioning Actuator Products:

Lintech has available two different high precision worm gear driven rotary positioning stages. One works well for light load applications, while the other positioning table is ideal for heavy load requirements.

Mechanical Rotary Table Configurations:

The 300 series rotary stage has a load capacity of 200 pounds, less than 150 arc-seconds of accuracy, and with worm gear ratios of 45:1, 90:1, and 180:1. This low cost rotary table is ideal for those applications requiring precise positioning using a servo or step motor system and is available with a 6, 8, 10, or 12 inch table top. Lintech has motor adapter brackets which can be used to connect any inch or metric motor to this rotary actuator. The 400 series rotary table is a heavy duty rotary positioning stage that has a load capacity of 1,000 pounds. It has a similar worm gear drive system with gear ratios of 30:1, 90:1, 180:1, 270:1 and 360:1. The large 225 ft-lbs of moment load capacity also makes this rotary positioning actuator ideal candidate for those applications that require both precise 360 degree positioning by a motor drive system along with the need to move a very heavy, off balance load. The motor mount for this 400 series rotary actuator is unique in that it can be rotated anywhere in a 360 degree plane, thus allowing the motor to be positioned in a place out of the way from other machine components. The large 4.5 inch through hole allows electrical cabling, pneumatic tubing, or other critical machine components to run directly through the stage.

170 Series Loading Capabilities

October 30, 2017

Some of the linear tables manufactured by Lintech have, as a standard option, the ability to choose the carriage length. The carriage is the portion of the linear table that moves on the linear guides as the screw or belt is driven. Having a longer carriage enables the bearing blocks to be spaced further apart and the ability to add more bearings under the carriage. This kind of flexibility results in a linear table that is capable of more demanding operating conditions.

Precision Linear Shafting & Bushings

October 16, 2017

Lintech offers precision shafting used for linear motion. There are many variations offered to meet requirements such as metric, pre-drilled, custom machining, stainless or plated.

Lintech has been providing linear shafting for decades and is also well suited to configure these components into a fully operational motion system complete with motors, controls, and programming. Of course, the precision shafting works in conjunction with ball bushings which are available in many configurations as well.

Precision shafting/bushings are great for applications requiring low torque, free rolling, and smooth motion. This type of linear motion product is also less complicated to align and therefore, less likely to “bind” during a move.

Lintech maintains significant stock levels on shafting and bushing types. All machining is done in southern California. In addition, the prices offered are extremely competitive.

Lintech 550 Series Belt Driven Table

October 2, 2017

The Lintech 550 series linear slides are designed to handle large loads at very high speeds. These linear actuators use a low friction, preloaded, recirculating ball bearing system, which rides on a single precision ground linear square rail. The single linear profile rail is mounted to a precision machined aluminum base, which offers rigid support over the entire travel of the table’s carriage.

The actuator load is mounted to a precision machined aluminum carriage, which has slots machined into it. These slots, along with the base mounting brackets, are used for mounting the user load. The drive system uses two pulleys, along with a high strength, steel reinforced polyurethane belt, which provides 8.071(205mm) inches of linear movement per revolution of the input shaft. The simple belt tensioning system allows for easy adjustment of belt tension by the user. The belt also acts as a cover, preventing debris from getting into the linear bearing and rails.

Downloading Lintech Product Models

September 15, 2017

Lintech offers a simple process for downloading 2D or 3D models in many different formats. Whenever a particular product overview page is selected from the home page(LintechMotion.com), in addition to the product specifications, there are many links associated with that product. Among those links is one called “Get a CAD File”. By clicking on that link, it is quite simple to create a model of the exact product variation desired and then downloading it in the desired modeling format. When on the product overview page, you may also notice a link which directs you to a page where a price can be easily calculated for the specific product variation. This helps to determine a budgetary cost as you’re creating the model – very convenient!

Lintech Tables for Vacuum and Other Demanding Situations

August 30, 2017

Lintech provides tables suited for a wide variety of unique applications. After careful consideration of all of the application requirements, Lintech can often arrive at a solution. Tables for “higher vacuum” applications can’t contain certain materials within the chamber. Lintech has provided tables for many vacuum applications having requirements in addition to a vacuum environment. Linear tables can also be modified so they are suitable for applications requiring the ability to withstand for corrosive environments.

Large Custom Lintech Assemblies

August 16, 2017

In previous blog posts, there have been references to the ability of Lintech to provide slightly modified catalog linear tables as well as some more unique linear motion solutions. Lintech also has the capability to do some very large and complex multi-axis motion systems.

The image above reflects a very large system with a large number of travel axes. Lintech was responsible for building the frame, all the mechanical components for the axes of travel, as well as the motors, controls and programming of every axis. The structure above was produced for a company building aircraft tooling.
