From spur gears to gear racks, gears are the building blocks of any mechanical power transmission system, transferring rotational force between shafts while adjusting speed, torque, or direction. 3BG Supply stocks a wide selection of industrial gears in metal and engineered plastic, and can source hard-to-find or custom gears through our supplier network. Explore our full gear and gear rack category or contact our team for help specifying a gear for your application.

FAQs
What types of gears does 3BG Supply carry?
3BG Supply stocks a range of industrial gears, including spur gears and gear racks, alongside complete gear boxes and gear reducers for finished drive assemblies. Our team can help you find the right style if you are not sure which gear type your application calls for.
How do I choose the right gear for my power transmission system?
Start with the type of motion you need to produce (rotational-to-rotational or rotational-to-linear), then narrow down by required torque, speed, and available mounting space. Our experts can help translate those requirements into a specific gear type and size.
What's the difference between a spur gear and a gear rack?
A spur gear is a round gear that transmits rotational motion between parallel shafts, while a gear rack is a straight, toothed bar that converts a pinion's rotation into linear motion. The two are often paired together in rack and pinion drive systems.
Can 3BG Supply source custom or hard-to-find gears?
Yes, in addition to our stocked gear lines, 3BG Supply can source custom and hard-to-find gears through our supplier network to match legacy equipment or unique specifications. Contact our team with your prints or sample part for a quote.
What materials are industrial gears typically made from?
Industrial gears are most commonly made from steel or cast iron for heavy-duty applications, with hardened or ground teeth for improved wear resistance and load capacity. Lighter-duty or noise-sensitive applications may instead use engineered plastics.
