PBB Concealed Bearing Hinges

What Are Concealed Bearing Hinges?

Concealed bearing hinges were specifically designed for internal and external doors to provide a seamless, low-maintenance operation, making them ideal for use on heavy doors, doors with automatic closers, and those subject to high levels of foot traffic.

With their modern bearings, these hinges require minimal amounts of grease and offer self-lubricating properties, reducing the need for maintenance.

Common Applications for Concealed Bearing Hinges

• Corrosive Environments: For doors and hinged furniture in corrosive and harsh environments, offer long-lasting performance with minimal maintenance.
• Fire-Rated Doors: These are concealed-bearing hinge designs that are specifically rated for fire doors and can withstand high temperatures for extended periods, maintaining door integrity during a fire and ensuring safe building evacuation.
• Internal Doors: Mild steel concealed bearing hinges bring internal doors to life with their smooth and silent operation, lessening noise and disruptions.
• Weather-Exposed Environments: Concealed bearing hinges are commonly used in harsher environments where hinges are exposed to weather conditions and humidity, such as marine and coastal applications.
• Security Sensitive Areas: Some concealed-bearing door hinges offer tamper-resistant features, which makes them suitable for doors in spaces such as server rooms, data centers, or other areas demanding additional security.
