Induction heaters help mount bearings safely

A line of induction heaters avoids overheating or preloading, and heats only the bearing — not the unit or yoke, according to the manufacturer. An automatic demagnetizing cycle eliminates residual magnetism, which can attract contamination by drawing metal particles into bearing raceways.

The TIH120 system heats large bearings, couplings, and other components with recommended maximum weight of 550 lb. It includes a 0 to 60-min timer. The TIH060 has a capacity of 8 kVA and a 50% reduction key for small components, making it versatile. Maximum bearing weight is 132 lb. The TIH030 is for bearings in the 66-lb range and has a 0 to 60- min timer. The portable TIH025 comes with a dial timer. The compact TIH010 is for bearings of 10 lb or less.

Solenoid-operated indexing clutch

The SP-1611 series integral solenoid wrapped-spring stepping clutch is unidirectional, for CW or CCW operation. Torque capacity is to 20 lb-in. and indexing accuracy is 62 deg. Errors are noncumulative. Indexing increments are from 1 to 4 steps. Bores are 0.250 and 0.312 in., and 6 and 8 mm. Options include an output anti-overrun and a phasing clamp for infinite phasing. Machine Components Corp., Plainview, N.Y. Plated roller chain resists rust Nickel-plated, rust-resistant roller chain is well-suited for drives that are used outdoors, such as agricultural equipment, or for indoor washdown equipment. All chain parts are nickel plated to protect against water-induced corrosion. Single or double pitch is available in 10-ft lengths with a light petroleum lubricant. Chain is also available unlubricated and in custom lengths.

Superfast programmable control

A programmable industrial computer, the PiC900 Turbo2, uses 80486SX/DX microprocessors to achieve high-speed information sensing, logic, and process control combined with easy programming and networking. Two versions are available: a 25-MHz configuration with math coprocessor, and a 16-MHz model without a coprocessor. The faster unit scans ladder diagrams at 78 msec per Kbyte.

The 16-MHz version operates at 96 msec per Kbyte. The faster version scans application programs up to seven times faster than the standard PiC900, assisted by a cache memory. It also features linear and circular interpolation of up to 16 axes. Potential applications for the new units include packaging, paper converting, printing, food processing, plastic injection molding, plastic film production, and metal cutting.
