Product Introduction
A journal bearing is a type of sliding bearing that utilizes a lubricating oil film to support a rotating shaft. During operation, a stable oil film forms between the journal and the bearing shell, minimizing direct metal-to-metal contact and reducing friction and wear.
Bearing Structure
The bearing shell provides structural strength and dimensional stability, supporting the loads encountered during equipment operation.
Material Options:
• Carbon Steel
• Cast Steel
• Bronze
• Stainless Steel
Serving as the sliding contact surface, the Babbitt alloy offers low friction, excellent conformability, and embeddability, thereby protecting the journal and enhancing operational reliability.
Designed according to operating conditions:
• Oil Groove
• Oil Pocket
• Oil Hole
• Forced Lubrication
Core Product Advantages
High Load-Carrying Capacity
Utilizes high-strength shell materials and optimized structural designs to enhance radial load-carrying capacity, meeting the demands of long-term operation in large rotating equipment.
Low Friction & Reduced Wear
Precise machining controls bearing clearance and optimizes lubrication, reducing frictional losses and improving equipment operating efficiency.
Reliable Babbitt Bonding
Employs specialized Babbitt casting processes to enhance the bond strength of the lining, minimizing the risk of delamination during operation.
Long Service Life
Combines wear-resistant materials, precision machining, and surface treatments to enhance bearing durability, making it suitable for continuous operating environments.
