BSA is the Forum that Keeps Bearing Companies Rolling
In today’s increasingly competitive global economy, industries and the companies that serve them are always looking for an edge. Price and quality being routinely accepted as a given, businesses—large and small—are always looking for a little help. For the worldwide bearing industry, that help exists in the form of the Bearing Specialists of America (BSA).

High-Capacity Bearings Carry the Load for Chinese Gearbox Manufacturer
Th e signing of a contract for more than 5,000 sets of SKF’s latest high-capacity cylindrical roller bearings (HCCRB) for wind turbines will impart added load-carrying capacity, more reliability and longer life to the Nanjing Gear Company’s (NGC) line of gearboxes for wind generation applications.

Selection and Performance Criteria for Power Transmission Couplings, Part II
Part I of this article appeared in the October 2008 issue. It provided an overview and general classifi cations of power transmission couplings, along with selection and performance criteria for rigid couplings and misalignment-compensating couplings. Part II continues the discussion with selection and performance criteria for torsionally flexible and combination-purpose couplings.

Improved Sealing Technology Extends Equipment Life
Th e primary sources of bearing failure are lack of lubrication and contaminant ingress. Industrial sealing devices are the primary protection against bearing failure. When the sealing device fails, bearing failure is imminent. Th erefore, extending the life of sealing devices extends bearing life and in turn improves equipment uptime.
