This bearing protection ring lasts for the life of the motor
A split-ring version (photo) of the Aegis SGR Bearing Protection Ring comes in halves for easy installation. For variable frequency drive controlled a.c. and d.c. motors, the SGR split ring protects bearings from electrical damage caused by circulating or shaft currents. This maintenance-free ring lasts for the life of the motor, independent of speed. Its conductive microfibers work with virtually no friction or wear and are unaffected by dirt, grease and other contaminants. It is available with mounting hardware in sizes to accommodate motor shafts with diameters up to 6-in. By shunting shaft currents to ground, the SGR prevents "bearing least resistance" and reduces noise, vibration, bearing failure and motor failure. - Electro Static Technology, Mechanic Falls, Maine

oils and coolants will not affect these rotary encoder collars
This standard line of rotary encoder collars (photo) can be mounted on virtually any shaft to provide speed-sensing capability from their outer diameter or face using a variable reluctance sensor. Made of anodized aluminum, these fully-split, two-piece designs come in 11 standard sizes from ½-in. I.D. by 2-in. O.D. or 3-in. I.D. by 4.5-in. O.D., and either 12, 20 or 24 steel targets. Unaffected by oils and coolants, these encoder collars are suitable for a wide range of new and retrofit applications. Special bore configurations, target locations and custom sizes are also offered. - Stafford Manufacturing Corp., North Reading, Mass.

Create matte, satin and other fine finishes on metals
For finishing surfaces, the PTX Eco Smart finishing machine (photo) has balanced straight-line handling, high torque and electronic speed control. It produces matte, satin and other fine surfaces up to a mirror finish on steel, stainless steel and nonferrous metals. The PTX is also suitable for coarse grinding jobs such as removing welds, deep scratches, oxidation, rust and paint, as well as for polishing inside corners. It has an abrasive mounting system that eliminates vibration, and the grinding and polishing wheels can be changed in seconds. The finnedshaft design of this finisher makes it vibration-free during operation and ensures 100% concentricity. - CS Unitec, Norwalk, Conn.
