WM Berg Inc Products

W.M. Berg Inc. manufactures a complete line of precision made, high quality couplings. Available in inch and metric sizes and many styles to accommodate any design requirement. Couplings can be placed into the following four categories:

1. Information Transmitting Couplings – These zero backlash high torsional rigidity couplings, are for precision positioning applications where constant velocity is required for accurate
   feedback control.
2. Shock Absorbing Couplings – As a result of flexible plastic members connecting their hubs, these couplings dampen vibrations and shock loads and electrically insulate shafting.
3. Misalignment Couplings – The sliding center elements of these couplings compensate for lateral and angular misalignment caused by tolerance buildup or as a result of mounting.
4. High Misalignment Couplings – These couplings allow the designer to have shafts that are intentionally offset, laterally or angularly, by a large amount.

Designed by practical engineers for use in all mechanical and electro-mechanical breadboard prototype work, test fixture and servo control system applications.

• All Kits may be enlarged at a later date by the addition of parts from this catalog (see Parts List).
• Kits are supplied with an attractive carrying case, felt lined to protect the high quality precision gears and associated parts.
• The supplemental parts kit is a complete precision parts stock room that complements all of the master parts kits. It has a basic selection of the most commonly used parts.
• Replacement parts are always available from stock.

Ideal for use in:

• Military Applications
• Industrial Operations
• Test Evaluation
• University Research
