Linear actuators are used in many applications and need to meet several specifications in order to produce a well made product. For instance, most machine shop tools need to be long lasting, strong and able to maintain repeatable close tolerance levels to keep product quality high.
Whether you need to replace an existing analog with a digital linear actuator, or you need to build your automotive machine shop with a specialized automotive linear actuator, you need to keep several things in mind:
Find local linear actuator distributors
Buying from local distributors of linear actuators means you'll have a place to turn when products break. Purchasing your electric linear actuators or industrial linear actuators overseas means long wait time for replacement and possible warranty problems. Research your supplier's location and linear actuator manufacturers' location and you'll have the benefit of supporting the local economy as well.
I recommend: Bishop-Wisecarver Corporation has a wide variety of actuators for all sorts of needs and a comprehensive online quote form so you get the product with the right specifications for the job. They are based in California, but they have field service centers all over the continental 48 states.
Macron Dynamics' products are made in the USA and carry a lifetime warranty.
Ask for assistance with your linear actuator application
There are many uses for linear actuators from tool and die making to hydraulic lift applications in the automotive industry. To get the right specifications for your application, it's best to get some guidance from the supplier.
I recommend: Tolomatic specializes in custom designing motion solutions for their clients and have supply centers all over the United States. You can ask their actuator expert to help you build a custom solution for your needs.
Burr Engineering also makes custom solutions but they have an online quote sheet so you can fill in your specs for the job before you receive a no obligation quote.
Be sure that the linear actuator, controller and other parts are compatible
Checking the spec sheet on your linear actuator to be sure it is compatible with existing equipment might be boring, but it's necessary to get the right linear actuator controller and actuator to do the job. You'll also need to check the supplier's and manufacturer's recommendations on installation to get the best performance and longest life out of your equipment.
I recommend: Buy all your needed equipment from the same manufacturer and you generally have built in capability.
Ultramation has both two and four piston thruster type linear actuators in which parts are available.
Ultra Motion carries both actuators and controllers so your sure to not have compatibility issues.
