BSA has a new short-body series of plastic anti-backlash nuts with ActiveCAM. Screw sizes include the 3/8-in. diameter XC-3700SH and the 1/2-in. diameter XC-5000SH. Offered in both threaded or flange-mount versions, these compact nuts are able to maximize usable stroke due to their reduced length. The nuts can be run without additional lubrication, making them suitable for clean environments and areas with difficult access.

Low-cost condition-monitoring instruments are easy to use

New from MCM is a line of instruments and monitors, based on acoustic emission technology, for the condition monitoring of rotating machinery. The AE signals are processed in two parameters, Distress and dB Level. Typically, a reading of 5 in Distress indicates a machine in good condition, while a reading of 20 means the machine is in poor condition. Included in the line are the MHC Memo, which includes PC software, and the MHC Solo, which offers just the Distress parameter and one-button use. These instruments are often used to assist with lubrication schedules, carry out spot checks, identify and prioritize before shutdown, confirm repair action and as a plant-wide monitoring tool.

New ratings broaden explosion-proof motor line

Baldor has added new ratings to its broad line of explosion-proof motors. These ratings now extend from 1/4 hp to 300 hp and NEMA 449T frame sizes. The company stocks nearly 350 different explosion-proof motors, including single-phase or three-phase AC, 50 Hz, severe-duty, jet pump, brake motors, DC for SCR drive permanent magnet or shunt wound, Super-E premium efficient, standard 1.0 or 1.15 service factor, NEMA C-face, close-coupled pump and Inverter Drive. The motors feature cast-iron frames and endplates on NEMA 143T frame sizes and larger, and are covered with a chemical-resistant, two-part epoxy paint. Applications include petrochemical plants, natural gas compressors, grain-handling equipment, fuel transfer and other hazardous-duty applications.

Acoustic vibration monitoring tells oilers when to grease

Lubrication quality and re-application cycles can be predicted when plant machinery is monitored using Acoustic Vibration Monitoring (AVM). SDT’s Ultrawave Acoustic lube applicator gives lubricators and reliability technicians the ability to digitally trend lubrication needs on rotating machinery. The power of data logging combines with the power to listen to the bearing as it is lubricated, helping avoid such pitfalls as over- or under-lubrication.
