Antifriction Bearing

A bearing that uses rolling elements — balls or rollers — to reduce friction between moving parts. Common in pumps, motors, and rotating equipment on job sites. Subcontractors should inspect and replace these during scheduled maintenance to avoid unplanned downtime.

Related Terms

Industry

A confidential tender submission where subcontractors submit pricing without knowing competitors' rates. All bids are opened simultaneously by the hiring company. This process is common in public sector and large operator contracts across oil and gas and construction.

Turnaround

Industry

A planned shutdown of a facility for maintenance, inspection, and repair. Turnarounds often require large numbers of contractors and subcontractors working intensive schedules.

Grid Interconnection

Industry

The process of connecting a power generation asset to the public electrical grid. For subcontractors, it triggers specific commissioning milestones, inspections, and sign-offs. Delays in interconnection approval can directly impact project timelines and invoicing.

Well Lifecycle

Industry

The full sequence of a well's existence, from drilling and completion through production and eventual abandonment. For subcontractors, each phase represents distinct scopes of work, crew requirements, and contract opportunities. Understanding the lifecycle helps you anticipate project transitions and position for follow-on work.

Tolerance Zone

Industry

The acceptable range of variation allowed in measurements, materials, or workmanship on a job site. Subcontractors must stay within these limits or face rework orders and cost penalties. Specs are set by the prime contractor or engineering drawings.

RAP (Reclaimed Asphalt Pavement)

Industry

Milled or crushed material salvaged from existing asphalt surfaces during road removal or rehabilitation work. Subcontractors reuse RAP as base material or blend it into new asphalt mixes, reducing material costs. Proper handling and testing requirements may apply depending on project specs.
