Precision linear shafting and the associated ball bushing bearing products have been around for many decades. They allow for fairly precise, low torque linear motion. The shafting is often machined to accommodate a particular design layout and it can just be held via end supports or underneath along the entire shaft length for a more rigid design.
However, we live in a “high tech” world. These products are can get overlooked, their features and benefits not properly evaluated.
Although Lintech offers many other linear products, continuous efforts have made to keep adequate inventory levels of these products, and to maintain some of the BEST prices available in the marketplace.

Lintech manufactures many tables, both screw and belt driven. Part numbers for Lintech tables are a bit lengthy but they describe the component breakdown for the table quite well. For instance, the ball screw “callout” for the table, when reviewing the specifications, will identify not only the screw diameter and lead, but also if the screw has a preloaded (PL) or non-preloaded (NPL) nut. Some other table vendors may enable you to extrapolate from a “bidirectional repeatability” specification, whether or not the screw is preloaded (if there is a bidirectional repeatability specification given). But this requires more time, thought, and maybe assumptions. Many manufacturers don’t offer a table with a choice for preloaded/non-preloaded screws. You get what they offer OR you have to go down the “custom” path which can be expensive and come with a longer lead-time.
The same applies to the rest of the Lintech part numbers. They are descriptive and you have lots of choices while still choosing from standard table options having short lead-time. So, in the end, you save time by having so many choices from one product line.

Often times when designing a linear motion system, the designer is targeting very accurate positioning. Much needs to be considered under that umbrella of accurate positioning. One of those considerations is deflection of the linear device. Deflection in a linear motion system means how much sponginess, deformation or deflection of the mechanical parts under the application loads and speeds. Obviously, the designer needs to calculate a level of deflection he/she can determine is acceptable.
Choosing a linear motion table with a higher load capacity will help to reduce deflection within the system. Often, though, this means a larger overall footprint of the linear motion system. The designer is not always able to accommodate the increase in size.
Lintech, however, has several linear motion table series which allow the designer to obtain a larger carriage (the driven portion where the application load is attached) size and/or more bearings to support that load. One example of that is the 170 series screw driven tables. In the example attached, when configuring the table, the designer gets to choose the number of bearings and the carriage length for the particular table desired. This is unusual. Most manufacturers’ choose the carriage length and number of bearings for you.
So, in the end, you can increase the capacity and have the ability to reduce the deflection further if needed, within the same footprint size. Again, this is unique.
If you would like more flexibility in configuring a table for your application, contact Lintech.
Lintech provides an option for motor mounts on screw and belt driven tables. When utilizing a motorized table for a screw or belt driven table, obviously you need a connection point between the motor used and the table. There are many different manufacturers and sizes of motors on the market and an intermediate gearhead may also be required. Lintech already has motor mount configuration designs for many motor manufacturers/models. However, when you add a motor mount, and may be a gearhead too, the overall length of the table really starts to grow. So, Lintech also has preconfigured motor “wrap” designs to enable a more compact overall length.
Lintech has a huge variety of table options and accessories to assist the designer with time savings. For more information on Lintech products, contact Lintech.
Lintech has been providing precision linear guides to many companies over the years. These square rails, also referred to as profile rails due to the varying shapes of the rail sides, have a higher load capacity than similar sized precision linear shafting/bushings. They are also more precise and require less physical space.
Lintech’s online ordering process allows for a quick, easy and inexpensive way for obtaining the size and configuration for a given application. When looking for a fast solution for linear guides, contact Lintech.
These days you can buy just about all of the things you want online and you can download all of the information you want about the products you need before you buy them. Some things are a little bit harder to buy online but the world is continuing to move faster and faster in this direction.
Lintech has offered downloadable models from their website for years now as well as the ability to purchase material online. This online purchasing segment continues to expand.
However, often the motion solution for a particular application is not so clear-cut when deciding upon a particular product to select. Every application has a different set of requirements to contemplate. Therefore, multiple cost/benefit options need to be pursued and evaluated before a type of product emerges as a viable option. After this evaluation process, many times there is no “catalog” solution which is obvious and a custom system seems like the best route to follow.
Lintech has built a significant portion of their business providing custom motion solutions. Customers who inquire may have already completed exhaustive searches looking for an off-the-shelf solution only to determine the fit is not suitable. They may recall in their searches that Lintech has positioned themselves as a custom linear motion system provider. Lintech has US based manufacturing people and machinery to discuss, pass files, and arrive at the best custom solution suited to the constraints of an application.
We had a customer recently looking to make some quick moves. They also needed to move a significant load and maintain motion that was accurate and fairly repeatable. We ended up directing the customer to the 180 series belt drive.
The 180 series is flexible in terms of its capacity since you can choose from different “standard” carriage lengths with 2, 4 or 6 bearings for load support. It is constructed with precise and rigid square rail linear guides as opposed to systems using plastic or steel roller wheels. 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.
