Spherical bearings. Suitable for such industrial applications as off-highway vehicles, agricultural equipment, mining and logging equipment, packaging and textile equipment, and robotics, these spherical plain bearings are available in standard industrial bore sizes from 1/2- to 12-in. as well as metric sizes from 4mm to 300mm. Five basic types of standard radial bearings are offered, while custom sizes are available upon special request. AST Bearings, 115 Main Rd, Montville, NJ 07045-9299. 800-526-1250. Circle 563.

Flat encoder. The FM700 hollow-shaft encoder is 27mm long (31mm with dust cover), and provides up to 2048 cycles per revolution. It operates in harsh environments including high shock, vibration, oil, moisture and other contaminants. The supply voltage is 5.0 VDC with an operational temperature range of -30 to 90°C. The FM700 is automatically aligned and accommodates up to 1.0mm (0.039 in.) of shaft end play. Admotec Inc, 85 Mechanic St, Lebanon, NH 03766-1500. 603-448-7000. Circle 564.

Parallel grippers. EGP grippers are ideal for handling small parts in confined areas when the preferred power source is 24 VDC. Units are double acting for internal or external gripping applications. They are available in 2 jaw styles, 2 jaw travels, and with mounting options on three sides of the gripper for maximum versatility. Optional proximity or Hall effect switches are available for indication of jaw position and integration with the system interface module. PHD Inc, PO Box 9070, Fort Wayne, IN 46899. 219-747-6151. Circle 565.

Motor feedback system. The Sincos line was developed for the high-end drive market, particularly for applications requiring a C-axis for high accuracy. Sincos provides multi-turn absolute feedback accuracy to ±5 arc seconds, resulting in drive system accuracy to ±30 arc seconds or less. Single-turn or multi-turn absolute position information (to 4096 turns) over an RS485 link is provided, as is separate feedback for the velocity and position servo loops. Stegmann, 7496 Webster St, PO Box 13596, Dayton, OH 45413. 937-454-1956. Circle 566.

Shaft collars. These collars feature custom configurations including hex, square, metric, radial, keyed and threaded bores; drilled and tapped face holes; and milled ODs. Machined with tolerances to 0.0005-in. if required, they are available in one- or two-piece clamp type and set screw styles and can incorporate a variety of grooves and hinges. They are available in a variety of metals, alloys and engineered plastics. Stafford Manufacturing Co, PO Box 2370, Woburn, MA 01888. 978-657-8000. Circle 567.

LVDT controller. The MP1000/2000 LVDT readout/controller features enhanced speed and, on the MP2000 version, a simultaneous dual channel display. It also features a 16-bit analog-to-digital converter. The readout/controller is an ideal fit for LVDT-based weighing systems, RS-232 data collection for SPC purposes and roller gap control. Other applications include concentricity gages, tank level control and part classification. Lucas Control Systems, 1000 Lucas Way, Hampton, VA 23666. 800-745-8008. Circle 570.

Rotary actuator system. The Compacta is an electric rotary actuator system that is smaller and more compact compared to conventional gear motors, which makes it easier to mount. It offers built-in limit switches, low weight, a wide range of gear ratios and many standard options that permit a fully customized unit to be made from standard stock parts. Morat Inc, 1967 Main St, North Reading, MA 01964. 978-664-6800. Circle 571.

Air bearing platform. The XY ABS-10 assembly offers a low profile and can be mounted on a granite or Anocast composite base. It is available in travels from 150mm to 1000mm. Excellent repeatability of flatness (¾0.1µm) makes it ideal for applications such as inspection, surface mapping and CMM. Accurate position feedback is provided by an optical encoder with resolution to 0.02µm, for both point-to-point and constant velocity measurements. Anorad Corp, 110 Oser Ave, Hauppauge, NY 11788. 516-231-1995. Circle 568.

Optical encoder. This two-channel quadrature incremental optical encoder is ideal for motion detection in printers, plotters, tape drives, positioning tables, automatic handlers and other motion-control applications constrained in space and cost. Supplied in a 11mm diameter package, the HEDR-5300 encoder features a self-aligning mounting boss and a resolution of 160 counts per revolution.
