What Is A Gearbox?

A gearbox is a mechanical device designed to transfer rotational motion between two shafts, typically adjusting the speed or torque in the process. Gearboxes are used in industrial machinery to enable effective power transmission, decreasing inertia ratio, and amplifying torque. They are widely used in various applications, including manufacturing machinery, power generation systems, and transportation vehicles.

What Are Gearboxes Used For?

  • Machine Tools: Gearboxes regulate speed and torque in equipment such as lathes, milling machines, and drills.
  • Conveyor Systems: Gearboxes operate conveyor belts at precise speeds for smooth material handling and processing.
  • Assembly Lines: Gearboxes supply power to robotic arms and automated systems, enabling accurate and efficient assembly operations.
  • Paper Mills: Gearboxes are used in the machinery involved in the production of paper, maintaining seamless operation of equipment.
  • Steel Mills: Gearboxes deliver power to rolling mills and other machinery used in steel production and processing.
  • Chemical Plants: Gearboxes provide the necessary power for pumps, mixers, and various chemical processing equipment.

Did you know… Cross Company is an ESOP (Employee Stock Ownership Plan). Our ESOP started in 1979 and as of 2006, we are 100% employee-owned! Learn more about our ESOP and how that benefits both team members and our customers.
Did you know... the precision measurement group at Cross was founded in 1939 by our current CEO's grandfather, Jim King. That's a whole lot of calibration!
Did you know... A fingerprint weighs about 50 micrograms. We know, we weighed it! The residue left from a finger can actually make a difference in weight results which is why we wear gloves when we calibrate weights. For reference, a sheet of paper is about 4.5 grams, that’s 4.5 million micrograms.
Did you know… Cross Company has grown significantly since our start in 1954. Over the years we've acquired 26 companies! Today, our five groups have expertise in everything from industrial automation to precision measurement, and industry knowledge going all the way back to 1939.
