Bearing installation and removal is a precision MEICA task carried out during pump, motor, and gearbox maintenance on water treatment and process plant projects. Incorrect fitting causes premature failure, while removal often requires hydraulic presses, pullers, and induction heaters that present crush, burn, and electrical hazards. This talk covers the safe procedures for bearing work on UK construction sites.

Key Hazards

Crush injuries from hydraulic press or bearing puller under high force

Burns from induction heaters used to expand bearings for hot mounting

Eye injuries from metal fragments ejecting during press-fit operations

Back injuries from handling heavy bearings and associated housings manually

Control Measures

Use the correct bearing puller or press for the bearing size and interference fit.
Wear safety glasses and heavy-duty gloves during all press-fit and extraction operations.
Keep hands and fingers well clear of the press platens and puller jaws during operation.
Use an induction heater rather than naked flame for hot-mounting bearings onto shafts.
Handle heated bearings with insulated gloves and tongs to prevent burns during mounting.
Support heavy bearing housings with lifting equipment or mechanical aids during removal.
Clean all bearing seats, shafts, and housings before fitting new bearings to prevent contamination.
Check the bearing specification against the manufacturer's data before fitting to confirm correctness.
Record all bearing replacements in the maintenance log with part numbers and installation dates.

Remember

Use the correct puller or press for the bearing size and keep hands clear of moving parts
Wear safety glasses and heavy-duty gloves during all press-fit and extraction work
Use an induction heater rather than naked flame for hot-mounting bearings
Handle heated bearings with insulated gloves and tongs to prevent burns
Clean all seats, shafts, and housings before fitting new bearings to prevent contamination
