The WM Berg Company
Belts, Chains, Sprockets & Pulleys
WM Berg manufactures a wide variety of cable chains, molded belts, sprockets and pulleys. The belts consist of polyurethane plastic molded over either a single or double stainless steel core.
The belts are lightweight, self-lubricating, come in infinite lengths, are field spliceable with a stainless steel splice.
The stainless steel constructed chain series offers long life, high tensile loads, and is available in many different pitch configurations.
Comparable pulleys and sprockets are offered in stainless steel, aluminum, or plastic in bore size ranges of 1/8" (3mm) diameter to 1/2" (12mm) diameter and are available up to 300 teeth.
WM Berg manufactures several styles of gears. Each gear has and serves its own particular application.
Some of the styles include: spur, internal spur, helical, miter/bevel, anti-backlash, worm and worm wheel, racks and gearing assemblies. Their gears are available in several different pitches, hub designs, and materials.
Information Transmitting Coupling
Berg's Information Transmitting Coupling series offer zero backlash and high torsional rigidity. They are ideal for precision positioning applications where constant velocity is required for accurate feedback control.
The single piece Beamed couplings are offered in single, three and six beam design to offer engineers the largest design criteria available. They are manufactured in stainless steel, aluminum and Delrin.
We also carry Wafer Spring, bellows and sleeve couplings within this group. This product line is also available in metric sizes.
Shock Absorbing Couplings
The Shock Absorbing Coupling series, as a result of flexible plastic members connecting their hubs, dampen vibrations and shock loads as well as electrically insulates shafting.
The series is maintenance-free and quiet running with no moving parts.
The neo-flex model is available in pin hub and clamp hub style. 1" Angular misalignment (maximum), .005 shaft misalignment (maximum).
The sliding center element of the Misalignment Coupling series compensates for lateral and angular misalignment caused by tolerance buildup or as a result of mounting. They are corrosion resistant, and require no lubrication.
Also available in metric sizes.
High Misalignment Couplings
The High Misalignment Coupling series allows the designer to have shafts that are intentionally offset, laterally or angularly, by a large amount.
The Power Drive cores are designed to transmit rotary motion continuously in one direction of operation. The flexible shaft is constructed of quality high carbon wire and wound on the most modern automatic winding machines.
Precisely controlled stress relieving is utilized to provide optimum flexibility and smoothness. The range of maximum parallel misalignment can be from as little as .063 to as much as 3.770. Also available in metric sizes.
In addition WM Berg manufactures:
- Dowel Pins
- Gear Boxes
- Lead Screws
