Lubrication: Users must follow the owners’ manual when selecting the lubrication type and quantity. Using the wrong lubricant or putting too little in the gearbox will cause damage to the gearing and bearings. On the contrary, adding too much lubrication may cause the gearbox to overheat.

Overhung Loads: Belts and chains put a load on the end of the gearbox input shaft. This can also occur when flywheels, rigid couplings, and other devices are mounted on shafts. If this exceeds the overhung load limit of the gearbox, shafts and bearings will be damaged.

Contamination: The gearbox should be protected from the ingress of water and other contaminants. Foreign substances can reduce the effectiveness of the lubricant to prevent metal-to-metal contact in the gears and bearings. Excessive water in the gearbox will also lead to rust inside the drive.

Improper Alignment: The motor, gear drive, and driven equipment shafts should run true to each other. Good alignment will reduce unexpected load on the shaft extensions, bearings, and prevent looseness in the application that leads to impact damage. Misalignment will put excess pressure on components and contribute to wear and tear damage.

Excess Load: Running a gearbox over its nameplate load limit will cause damage. Keep in mind that the torque limit of the gearbox is defined by the motor power and speed, so a change to either can affect its performance.
