The Role of Bearings in Industrial Machinery

Selection and Maintenance

Bearings may be small components, but they play a massive role in the efficiency, reliability, and longevity of industrial machinery. From conveyor systems to gearboxes and electric motors, bearings reduce friction, support rotating shafts, and help manage loads. At Baldwin Supply, we know that selecting and maintaining the right bearing is essential to keeping operations running smoothly.

Why Bearings Matter

• Bearings enable smooth rotation and movement within industrial equipment, reducing wear and heat generation. Their primary functions include:
• Minimizing Friction: Bearings create a smooth surface between moving parts.
• Carrying Loads: They support radial and axial loads depending on the application.
• Ensuring Precision: Precision bearings maintain alignment and reduce vibration, extending machinery life.

• Understanding the right type of bearing for each application is critical. Here are some of the most commonly used:
• Ball Bearings: Ideal for lower-load, high-speed applications. They handle both radial and axial loads.
• Roller Bearings: Designed for heavier radial loads. Variants include cylindrical, spherical, and tapered rollers.
• Mounted Bearings: Housed in ready-to-install units, perfect for conveyors and heavy machinery.
• Thrust Bearings: Best for high axial load applications like vertical shafts or worm drives.

• When choosing the right bearing, several factors must be considered:
• Load Type & Size: Determine the radial and axial load the bearing must support.
• Speed: High-speed applications require bearings with low friction and precision tolerances.
• Environment: Exposure to dust, moisture, heat, or chemicals may require special seals or materials.
• Mounting & Alignment: Misalignment can lead to premature failure; self-aligning bearings may be ideal in some cases.
• Lubrication: Some bearings are pre-lubricated, while others require a tailored lubrication schedule.

• Even the highest-quality bearing won’t last without proper care. Preventive maintenance is key to maximizing uptime and minimizing costly breakdowns:
• Routine Inspections: Look for signs of wear, vibration, or overheating.
• Proper Lubrication: Use the right type and amount of lubricant, and reapply on schedule.
• Alignment Checks: Misalignment can cause uneven wear—check shafts and housings regularly.
• Clean Environment: Dirt and debris are common causes of premature bearing failure.
• Replace When Necessary: Don’t wait for catastrophic failure—monitor bearing condition and replace proactively.
