June 15, 2021

The Lintech 180 series belt drive is a great general purpose option for a belt drive as it is very reasonably priced and has a load capacity up to 8400 lbs. when you select the 4 bearing carriage option. It is only 75mm tall and 152mm wide. There are numerous standard travel options but there is always the ability to specify something custom.

As usual, Lintech offers any and all of the “bells & whistles” necessary to finish the system including motors, controls, gearheads, switches, etc. Generally, these accessories are all available within a 2-4 weeks lead-time. So, if your application calls for a belt drive due to higher speeds, long travel or another factor, take a look at the 180 series. Lintech also has the 120, 140 and 550 series belt drives to suit different capacities or size constraints.

Miniature Linear Guides

June 1, 2021

The MR series is a miniature 2 row re-circulating profile rail linear guide bearing. The block and LM linear profile rail are made from 440c stainless steel and there is an option for seals on both ends of the block and on the bottom of the block. There is also an option for a self-lubrication block and another for a reinforced block seal which allows the block to move at a higher rate of speed. Three different accuracy grades are available – N grade, H grade, and P grade. The blocks are available in either a standard or long length, while the rail width is available in a normal or wide version. These various sizes allow for different block load capacities.

IP30 Screw Driven Linear Table

May 17, 2021

The Lintech 610 series screw driven linear ENCLOSED slides are designed to maximize performance while minimizing physical size and cost. These linear positioning systems use a low friction, preloaded, recirculating linear ball bearing system, which ride precision ground linear rail guides. The linear rails are mounted to an extruded aluminum base, which offers rigid support over the entire travel of the table’s carriage. The load is mounted to a precision machined aluminum carriage, which has threaded stainless steel inserts for high strength and wear life. There are 38 different acme and ball screw options that offer high efficiencies and long life at an economical price. These linear tables are designed to allow for numerous options. They include EOT and home switches, linear and rotary encoders, power-off electric brakes, motor wrap packages, and versatile mounting brackets for multiple axis applications.

Lintech can build standard positioning systems in 2-3 weeks. Customs and/or multiple axis systems are very common and not long lead-time solutions.

Lintech Shaft & Carriage Assemblies

May 3, 2021

Shaft & Carriage Assemblies were one of the first custom products which Lintech made many years ago. These consist of pre-assembling shafts onto a support and mounting pillow blocks on a plate to create a carriage. These assemblies soon became a standard Lintech product line and they are still widely utilized in linear motion applications.

Lintech shaft and carriage assemblies are offered in a variety of shaft diameters and overall lengths. Carriage assemblies are also made to fit the shaft assemblies and can be from 6 inches to 30 inches long. These assemblies can be ordered to be suitable for use in applications where there may be corrosion concerns. Carriage assemblies can be obtained with hand wheel locks which provide for a manual lock to the shaft.

Lintech Online Tools

April 15, 2021

Lintech manufactures linear motion systems for precision positioning. Part of a task to create a precision positioning system is to select a motor package which will move the specified load at the desired speed under the given conditions. Lintech offers online tools to aid in selecting a motor package with the necessary torque and speed capability.

On the main page there is a link to “sizing apps”. By clicking on that link, you will be taken to a page where you can select the Lintech table you have selected and then you will be prompted to fill in your application specifics in order to calculate the torque and speed required by a motor to perform your task.

Also included on the page with the sizing tools are other useful tools often used for determining the appropriate linear system.

Lintech ARC Linear Guides

April 1, 2021

Lintech offers a wide variety of profile rail linear guides. Many different options to compete and dimensionally match with lots of other manufacturers guides. The ARC series is another one of the models which falls into that category. The market niche Lintech has earned a position in, is low cost and availability while still offering quality and performance. Many of the actual linear guide “applications” we encounter do not even begin to test linear guide performance limits. So, it comes back to proper sizing. If you can offer a good product which is used properly, while also offering a great price and quick deliveries, you’ve got something!

Lintech 200 Series Linear Table

March 15, 2021

The Lintech 200 series linear translation stages are designed to maximize performance while minimizing physical size and cost. These linear motion stages use a low friction, preloaded, recirculating linear ball bearing system, which ride on precision ground linear square rail guides. The linear profile rails are mounted to a precision machined aluminum base, which offers a rigid support over the entire travel of the table’s carriage. The load is mounted to a precision machined aluminum carriage, which has threaded stainless steel inserts for high strength and wear life. There are 22 different acme and ball screw options that offer high efficiencies and long life at an economical price. These linear stages are designed to allow for numerous options. They include End-Of-Travel and Home switches, linear and rotary encoders, power-off electric brakes, motor wrap packages, and versatile mounting brackets for multiple axis applications.

The 200 series table is 95mm tall, 216mm wide. It has an 8,800 pound capacity and a top speed of 1270mm/second.

Multi-Axis Mounting Configurations

March 1, 2021

Lintech provides standard or custom mounting brackets to mount multiple axes together in an assortment of configurations. In some cases one table can be mounted directly on top of another. However, often some sort of intermediate bracket is required in order to obtain the necessary orientation.

Since Lintech tables are used for high precision and significantly loaded applications, the brackets for different mounting arrangements need to be very strong and very accurate, not just a plate to which the tables can be attached. Hence, they represent a significant cost. Having many pre-configured standard designs allows for more efficient pricing.

Lintech will also perform the actual mounting of multiple axes to make sure all axes are aligned properly. In addition, they can also add motors, controls, switches, and etcetera, to complete the entire motion control system.

Ball Screw Housing Support Bearing Assemblies

February 15, 2021

As a “standard product”, Lintech offers four different types of ball screw housing support styles.

These configurations allow the designer increased flexibility to “fine tune” the design to obtain the most suitable components for a given set of requirements. For instance, if the design requires higher speeds and/or higher rigidity, you can weigh out the housing configuration differences, as well as every other ball screw design choice to achieve the best performance trade-off combination.

For assistance on determining the best design trade-off for your application, contact Lintech.

Turcite vs. Acme Style Lead Screw Nuts

February 1, 2021

Lintech offers different types of sliding element nuts in linear table screw driven systems. The terms “lead” screw and “ACME” screw are talked about frequently. An ACME screw refers to a specific thread form which is trapezoidal in shape. A lead screw refers to screws which utilize nuts which do not have rolling elements. They are just sliding on the screw. An ACME screw is a type of lead screw. Lintech offers ACME style lead screws as well as lead screws which incorporate the shape of thread used for ball screws. Lintech will utilize Turcite, a polymer material shaped to mate to the ball screw form.

Utilizing a Turcite nut on a ball screw form produces a drive mechanism that has less friction than an acme screw, thus potentially allowing for higher speeds and less input torque required from an attached motor for a given application. It provides smooth motion, low audible noise, and is ideal for vertical applications. Also, using the Turcite nut with high lead ball screws provides for faster linear speeds. A “downside” or maybe a benefit of an ACME screw HAS more friction. So, in vertical applications, it may be the design of choice because in a situation where power is “lost”, the friction could possibly hold the load in position vs. a “free fall” which is a potential problem.
