A Plain Guide to Industrial Bearings
A plain-language survey of the main industrial bearing families, from plain sleeves to ball, roller and thrust designs, and what each is built to carry.
Plant Equipment
Bearings and Power Transmission
How bearings, seals, couplings, belts and chains carry power through rotating machinery.
Ball Bearings Versus Roller Bearings in Machinery
How ball and roller bearings differ in contact shape, speed and load capacity, and how each handles radial and axial loads in everyday machinery.
Bearing Storage and Handling Before Installation
Clean handling and sensible storage habits that protect new bearings from corrosion, contamination and damage before they ever reach a machine.
Common Causes of Bearing Failure
How to read the visual clues on a worn bearing, from pitting and discoloration to scoring and brinelling, and trace each back to its likely cause.
Flexible Couplings and Shaft Misalignment
How common flexible coupling styles connect shafts, what types of misalignment they tolerate, and why leftover misalignment shortens bearing and seal life.
How Bearing Lubrication Works
How grease and oil keep bearing surfaces apart, how the two compare, and why lubricant choice, quantity and cleanliness matter for bearing life.
Roller Chain Drives and Sprockets
A plain look at how roller chain drives and sprockets transmit power, why chain lubrication matters, and what chain stretch really means.
Shaft Alignment Methods Explained
A general overview of straightedge, dial indicator and laser shaft alignment, what each can measure, and what to check before aligning any machine.
Shaft Seals and Why They Leak
How lip seals and mechanical seals keep fluid in and contamination out around rotating shafts, and the usual reasons they begin to leak.
V-Belts, Timing Belts and Drive Tension
How V-belt and timing belt drives differ, why belt tension matters for belt and bearing life, and the typical signs of a belt drive wearing out.
