SS BALL BEARING HINGES:
Fire rated ball bearing hinges are an essential component in fire doors, providing stability and durability while also helping to maintain the fire rating of the door.
Construction and Materials:
Fire rated ball bearing hinges are typically made of high-quality steel, which is able to withstand the high temperatures and stresses that occur during a fire. They are designed to support the weight of the door and provide smooth and quiet operation. The bearings are generally made of stainless steel or brass to ensure durability and longevity.
The hinges are also designed to meet specific fire ratings, which are based on their ability to withstand fire and prevent its spread and maintain the structural integrity of the door during a fire for a specified period of time, usually 30 minutes, 60 minutes, or 90 minutes and 120 minutes. Standard size for hinges are 4*3*3.
Fire rated ball bearing hinges offer a number of benefits in addition to their ability to maintain the fire rating of a door. These include:
Durability - Fire rated ball bearing hinges are designed to provide long-lasting performance, even in high-traffic areas.
Stability - The ball bearings in the hinges help to evenly distribute the weight of the door, providing stability and preventing sagging or warping over time.
Smooth operation - The ball bearings also provide smooth and quiet operation, making it easy to open and close the door.
Maintenance - Fire rated ball bearing hinges require little maintenance, and are designed to provide reliable performance for years to come.
Fire rated ball bearing hinges are a critical component in fire doors, providing durability, stability, and smooth operation while also helping to maintain the fire rating of the door. They are made of high-quality materials and are designed to meet specific fire ratings, ensuring that they are able to withstand high temperatures and prevent the spread of fire. Proper installation is the key to ensuring the proper functioning of a fire door, and should always be done in accordance with the manufacturer's specifications and local building codes. By choosing high-quality fire rated ball bearing hinges and ensuring proper installation, building owners and occupants can have confidence in the safety and durability of their fire doors.
1The first step in the installation process is to ensure that the hinges are the correct size and rating for the door. This information can be found on the packaging or the manufacturer's specifications.
2 Next, the door and frame must be properly aligned and securely fastened to ensure that the hinges are properly seated. The hinges should be installed on both sides of the door and should be evenly spaced to ensure proper weight distribution.
3 Finally, the ball bearings should be lubricated to ensure smooth operation, and any excess lubricant should be wiped away to prevent buildup and potential fire hazards.
