Tighten Specs to Reduce Motor Bearing Failures and Local Supply Risk

What happened

Process Online published a technical piece explaining that variable speed drives can induce common‑mode shaft currents that accelerate motor bearing wear. It details practical mitigations—shaft grounding devices, grounding brushes and insulated bearings—and notes sizing and availability limits for some options. Watch supplier stock for preinstalled solutions and whether buyers can contract for separable pricing and confirmed lead times

Why the category manager should care

Treat bearing protection as a mandatory specification element where VSDs are present because the failure mode is repeatable and costly

Key facts

• Practical mitigations: shaft grounding devices, grounding brushes, insulated bearings
• Notes on sizing and availability limits for some isolator options
• Recommendation to add grounding at purchase or preinstallation

What happened

An industry commentary argues that valves, sensors and the small control elements at the 'last metre' materially drive energy, water and long‑term process performance. The author recommends involving operations and automation early so lifecycle, maintenance and spares are specified before procurement decisions are final. Watch for RFQs that embed or fail to separate commissioning and lifecycle services

Why the category manager should care

Insist on RFQs that separate hardware, commissioning and lifecycle services because last‑metre choices shape long‑term maintenance and spares needs

Key facts

• Emphasis on lifecycle from installation through replacement
• Call to involve operations and automation earlier in procurement
• Focus on valves, sensors and last‑metre control as performance levers

What happened

Duratec announced it won a construction management contract at Orica’s Hunter Valley hydrogen hub and noted the award leverages recent local acquisitions and workforce. That creates a concrete regional demand signal for mobilisation, temporary labour and consumables tied to construction activity. Watch whether contractor self‑performance absorbs local supplier stock and creates short‑term replenishment gaps

Why the category manager should care

Expect regional demand pressure where major projects self‑perform; validate local supplier capacity instead of assuming national distribution will cover spikes

Key facts

• Duratec awarded construction management role at Orica Hunter Valley hydrogen hub
• Award leverages recent local acquisitions and workforce in the Hunter region
• Part of multiple local contract wins increasing self‑performance capability
