Key Features & Applications

01

Suspended seat design: The bearing seat is of a suspended structure and is installed on conveying machinery and other equipment connected by pipe threads, which can adapt to specific installation environments and usage requirements.

02

Easy installation: No need to design a complex bearing box separately. It can be directly installed at the designated position of the main unit through bolts. The installation process is simple and can effectively shorten the installation time of the equipment.

03

Good self-aligning performance: It can automatically correct the shaft center deviation caused by installation errors, shaft bending or shaft deflection, etc., ensuring that the shaft and the bearing maintain good concentricity during the operation of the equipment, reducing vibration and wear, and extending the service life of the equipment.

04

Strong load-bearing capacity: The outer spherical structure increases the contact area between the bearing and the bearing housing, enabling it to withstand large radial loads and certain axial loads. It is suitable for a variety of mechanical equipment with requirements for load-bearing capacity.

05

Good sealing performance: Generally equipped with double-layer sealing devices, such as contact rubber seals, etc., which can effectively prevent external dust, impurities, moisture, etc. from entering the bearing interior, and also avoid grease leakage, ensuring the normal operation of the bearing in harsh environments.

06

Convenient maintenance: Some models are equipped with oil injection holes, which facilitate the replenishment of grease during use, extend the service life of the bearings, and reduce maintenance costs.

07

Good universality and interchangeability: The bearing core and bearing housing have a certain degree of universality and interchangeability. When the bearing is damaged, the bearing core or bearing housing can be replaced separately without the need to replace the entire bearing assembly, reducing maintenance costs and difficulty.
