Product Overview

Summary: This Bearing and Seal Replacement Safe Operating Procedure sets out a safe, consistent method for inspecting, removing and installing bearings and seals on plant and equipment. It helps Australian workplaces minimise mechanical failures, protect workers from serious crush and entanglement injuries, and maintain compliance with WHS and plant maintenance obligations.

Bearing and seal replacement is a routine task across manufacturing, mining, utilities, agriculture and facilities maintenance, yet it carries significant safety and reliability risks if not completed correctly. Incorrect isolation, poor lifting practices, use of improvised tools or contamination during installation can lead to serious injuries, unexpected breakdowns and costly downtime. This Safe Operating Procedure provides a clear, step‑by‑step method for safely replacing bearings and seals on rotating equipment such as motors, pumps, conveyors, gearboxes and fans in line with Australian WHS expectations.

The document guides workers from pre‑job planning and lockout/tagout through to disassembly, inspection, correct fitting techniques and post‑maintenance testing. It embeds hazard identification and control measures at every stage, including guarding removal, hot work, use of pullers and presses, and managing lubricants and cleaning chemicals. By standardising the process, this SOP reduces variability between technicians, supports training and competency assessment, and provides evidence that your business is taking a systematic, risk‑based approach to plant maintenance under WHS legislation.

Key Benefits

• Ensure safe isolation, disassembly and reassembly of rotating plant in line with WHS requirements.
• Reduce the risk of crush, entanglement and eye injuries during bearing and seal removal and installation.
• Extend equipment life and reliability through correct handling, fitting tolerances and contamination control.
• Standardise maintenance practices across shifts and sites to improve quality and reduce rework.
• Demonstrate due diligence and compliance with Australian plant and equipment maintenance obligations.
