reoiling

Reoiling is the process of reapplying lubricant to mechanical components after initial lubrication to maintain low friction and prevent wear. It typically involves assessing lubrication needs, inspecting components for wear or contamination, cleaning surfaces if required, choosing a suitable lubricant, and applying it in the proper quantity and manner.

Applications include bearings, gears, chains, spindles, and other moving parts in industrial machinery, automotive and aerospace equipment, and hand tools. Lubricants can be mineral or synthetic oils, greases, or specialty lubricants. Selection depends on temperature, load, speed, seal compatibility, and material surfaces. Viscosity and base oil type matter.

Methods of application include manual brushing, oil cans, grease guns, and automatic lubrication systems. For precision, metered lubrication ensures consistent distribution.

Common pitfalls include over-lubrication leading to seepage and dirt buildup, under-lubrication causing wear, contamination from dirty applicators, and using incorrect viscosity. Environmental and safety notes: collect used oil for recycling; avoid spills; wear gloves and eye protection.

Frequency depends on equipment, operating conditions, and manufacturer guidelines; some systems use schedules, while others rely on condition monitoring to trigger relubrication. Regular documentation of lubrication events helps track service life and plan maintenance.
