Ball Bearing Hinges FAQs
What are ball bearing hinges used for?
Ball bearing hinges are designed for heavier doors and high-traffic areas. The built-in ball bearings reduce friction, allowing doors to open and close smoothly while improving durability over time.
Are ball bearing hinges suitable for fire doors?
Yes. Many ball bearing hinges are fire rated and suitable for FD30 fire doors when installed correctly. Fire doors typically require three certified hinges to meet safety recommendations.
What size ball bearing hinges should I use?
Most internal doors use 3 inch or 4 inch hinges. Heavier doors such as solid core or fire doors commonly use 4 inch ball bearing hinges for added strength and stability.
How many hinges should be fitted on a door?
Standard internal doors often use two hinges. However, heavier doors and fire doors should use three hinges to properly support the door and improve long-term performance.
What is the difference between ball bearing hinges and standard hinges?
Standard butt hinges rely on metal contact between hinge parts, which can wear over time. Ball bearing hinges contain small bearings that reduce friction, making them smoother and more durable for heavier doors.
Do ball bearing hinges need maintenance?
Ball bearing hinges require very little maintenance. Occasional cleaning and light lubrication can help maintain smooth operation, especially on doors used frequently.
