Sliding Bearings

1. High Load Capacity: Sliding bearings can withstand significant radial and axial loads, making them ideal for the high-load working environment of marine engines.

2. Wear Resistance: With proper lubrication, sliding bearings exhibit low wear rates, which extends their service life.

3. Strong Adaptability: They can operate stably in high-temperature and corrosive environments, making them suitable for marine engines in oceanic settings.

High-Precision Cylindrical Roller Bearings

1. High Rigidity: Cylindrical roller bearings offer higher rigidity, making them suitable for applications requiring high precision and stability, such as in marine engines.

2. Good Load Distribution: Due to the large contact area between the rollers and raceway, cylindrical roller bearings distribute loads more evenly, reducing localized stress concentration.

3. Suitable for High-Speed Operation: These bearings effectively reduce friction and heat generation during high-speed operation, meeting the high-speed requirements of marine engines.

Additional Notes:

A Portuguese customer has decided to purchase sliding bearings and high-precision cylindrical roller bearings produced by QIBR as equivalent replacements for TIMKEN bearings to meet their marine engine's high load capacity and long service life requirements. QIBR’s high-precision cylindrical roller bearings feature optimized designs, capable of handling large radial loads, particularly suitable for the high-load applications of marine engines. The precise matching of rollers and raceways ensures stable performance and long durability under heavy load conditions. QIBR’s sliding bearings are designed to provide smooth motion and reduce friction, with wear-resistant materials and precise manufacturing ensuring exceptional performance. These sliding bearings effectively reduce friction loss and enhance overall efficiency, especially in marine engine environments.
