Linear Guide Load Capacity

July 14, 2017

Linear guide load ratings are based upon some reference point of travel distance. Not all manufacturers use the same reference point. So, if you compared what seem to be 2 very similar linear guides, one may have a listed rating which is quite a bit better (or worse) because the capacity could be based upon 100Km of travel versus 50Km of travel, or vice-versa. If you intended only to reach 50Km of travel life, you could logically expect carry a higher load before failing from fatigue than if you needed to reach 100Km of life.

Load Ratings HRC Series

Not all load rating tables from the many linear guide manufacturers list the rated life reference on the load rating catalog page. Sometimes it is shown in the engineering section of the catalog. However, it should be considered during the design process of the motion system.

Lintech Custom Systems

June 30, 2017

Lintech is quite compliant with designers in their efforts to satisfy any special accommodation. Whether it is special environmental concerns, adding many types of mechanical or electrical accessories, fabricating custom components, software programming, different mounting configurations, motors & controls, etc.

Mounting Configurations

Lintech has a long history of building custom systems which include all the necessary accommodations to “finish” the linear motion package.

Lintech Linear Guide Price Configurator

June 14, 2017

Lintech provides a simple configurator to enable a designer looking for quick pricing on any linear guide variation. The configurator can also be used to calculate pricing on all the other Lintech products as well. It can save time versus calling a manufacturer, especially outside of the 8am-5pm hours.

Simply, select the series of product desired (or several to determine a comparison), select the specific configuration from all of the drop-down boxes, choose the number of blocks, rail length to the nearest mm, location of start hole(distance from end of rail to center of the 1st hole), and then hit “get price”.

The configurator is a great tool for obtaining quick pricing or comparisons on the fly.

Required Motor Torque

May 30, 2017

Lintech provides a tool for determining the required motor torque necessary to drive Lintech screw driven and belt driven linear motion tables. On the home page of Lintech’s website there is a link for “sizing apps”. Clicking that link takes you to a page which shows the different screw or belt models.  When you click on the model preferred, select the model specifics and the move profile desired. It is also necessary to have some specifications for the potential motor intended for the application. The program will calculate the torque needed from the motor to perform the designated move profile. Once the torque is calculated by the program, check the motor torque curves to make sure the motor selected has the torque available at the given speed.Sizing Apps Page

Lintech 200 Series Linear Table

May 15, 2017

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.

200 series Screw Driven Linear Stage

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

Encoders on Lintech Tables

May 1, 2017

Linear Encoders: If a linear encoder is supplied by Lintech, it comes mounted and aligned to the positioning table. This encoder operates via an LED pick-up of an etched strip on a glass spar which spans the entire length of the encoder. It is important NOT to make any adjustments to the encoder mounting. The encoder alignment is extremely critical and is important for proper accuracy, repeatability, and performance. The warranty is voided if adjustments are made to any part of the encoder or encoder mounting.

Rotary Encoders: If a rotary encoder is supplied by Lintech, it comes installed on the table opposite the motor mount end. This rotary encoder is shaftless and is physically mounted to the screw shaft or drive shaft extension on a belt drive table. It is important NOT to remove the rotary encoder from the positioning table. The glass disk is pre-aligned by Lintech for proper operation. Removing the encoder could affect its performance. The encoder is protected with a sheet metal cover, which is not totally sealed. Therefore, if splashing fluid or other materials is present, precautions should be made to redirect these materials away from the encoder housing since contaminants which penetrate the housing can cause encoder failure.

Ball Screw Assembly Lubrication

April 14, 2017

Every Lintech ball screw assembly requires a small amount of grease or oil for proper, long term operation. Lubrication will decrease system wear and the potential for oxidation of the ball screw surface. For most applications, a medium to heavy oil, light grease, or synthetic Teflon based lubricant is recommended. The many built-in pockets within the ball screw nut allow the adhesive properties of these lubricants to be stored for extended periods of time.

For high speed applications, a light grease is recommended, while the ball screw should NEVER be operated dry for any length of time. For some low speed and lightly loaded applications, a ball screw assembly can typically be operated without lubrication, but for the most part, this is not recommended. Use of WD-40, or other cleaning solvents, should strictly be avoided, as they can cause damage to the ball screw nut.

Because Turcite nut ball screw assemblies have a solid surface contacting a solid surface, sufficient lubrication becomes a must. If there is not proper lubrication, the higher frictional forces of these nuts will cause excess wear to the assembly, thus preventing required screw life from occurring. Applying lubrication directly onto the entire length of the screw on a regular basis is highly recommended.

All ball screw assemblies are shipped with a lightly coated rust preventative oil on the ball screw threads and ball nut. This oil is not meant as an operational lubricant. It is highly recommended that the proper lubricant be applied to the ball screw and linear rails prior to operation. Also, periodic re-lubrication helps assure that the rated life of the ball screw assembly is attained.

All End Support Housings do NOT require lubrication. The housings and bearings are internally lubricated for life, and sealed to prevent outside contamination from entry.
