The Bearing Specialists Association (BSA) has announced publication of its latest Bearing Brief, A Guide to Linear Motors. Linear motors are found in those applications where high speed, accuracy, or repeatability are required. As the Bearing Brief points out, mechanically driven linear products may have some of these attributes, only linear motors can have all of them.
A Guide to Linear Motors distinguishes between Voice Coil, Force Tube, Stepper, Hybrid, Brush DC, Induction, and Synchronous linear motors and includes a Quick Selection Guide and an easy-to-read chart of properties for each motor type.
Like all BSA Bearing Briefs, A Guide to Linear Motors is available for free download from Tools You Can Use on the BSA website www.bsahome.org. It's the latest in a series of more than 20 free, single-topic user bulletins designed to deliver expertise to meet the needs of the end user as well as bearing industry professionals. Bearing Briefs are ideal references on the shop floor and as a pass-along to end users. Special thanks to John Long, Applications Engineer, NSK Precision America, Inc., for authoring this Bearing Brief, and to Baldor/Dodge/Reliance and the Schaeffler Group for providing graphics.
Bearing Briefs are a program of BSA's Educational Services Committee. These special bulletins present summarized information on topics of interest to the bearings industry. Previous reports have included Bearing Repair, Bearing Installation Fitting, Ceramic Bearings, Wear Sleeves and Other Shaft Repair Options, Vibration Analysis, Seal Selection, Load Ratings and Bearing Life, The Domestic Bearing Industry: Investing in the Future, Status of Bearing Load Ratings, History of Adhesives, Plane Bearings, A Brief History of Bearings, Linear Bearings, Bearings for the Food and Beverage Industry, Ball Screws as Positioning Actuators, Spherical Plane Bearings, Planetary Roller Screws, Split Roller Bearing Technology, Bearing Mounting Tools, Reduced Operating Costs Through Condition Monitoring, Understanding Linear Actuators, Smart Bearing Technology, and The Best-Kept Secret in "Green" Technology. Bearing Briefs are just one of a variety of education and training programs and publications provided by the Association.
BSA is the "must belong to organization for authorized bearing distributors." An international service and educational organization of distributors representing a total of almost 100 companies distributing factory-warranted ball-, roller-, and anti-friction bearings and invited manufacturers of bearings and related products, the association's mission says, "BSA is the forum to enhance networking and knowledge sharing and promote the sale of bearings through authorized distributors.
