Failure to specify the proper motor for use in a hazardous location can have serious consequences - lost production, extensive property damage, and even loss of human life. Selection of the proper motor requires an understanding of Underwriters Laboratories' (UL) and National Electrical Code (NEC) class, group and division designations and the T code letters.

Sustainability is becoming one of the most important aspects within the power transmission business. Users demand low-maintenance drive systems with as little disruption as possible, and expect lifetimes of more than 10,000 hours. Approximately 40 percent of long-term gearbox leakages can be traced back to poor interaction between the radial shaft seal (RSS) and the lubricant. Thus, it becomes essential to analyze the tribological system as a whole, which includes the gear oil, seal grease (if required), elastomer material and design, and the shaft.
