Spherical plain bearing is a spherical sliding bearing whose sliding contact surface is an inner spherical surface and an outer spherical surface. It can be rotated and oscillated at any angle during movement. It is made by surface phosphating, blasting, inlaying, spraying and other processing methods. 

Spherical plain bearings have the characteristics of large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning and good lubrication. According to different types and structures, it can bear radial load, axial load or combined radial and axial load. The application scenarios are: water conservancy and professional machinery.

Our company distributes bearings of major brands with sufficient inventory.
We professionally provide GE/GEH/PHS/POS type bearings to provide you with the best quality service! If you have any needs, we can also provide you with brand (such as NTN, FAG, SKF, etc.) alternative services to meet your needs! Welcome to consult!


PRODUCT DESCRIPTION


1.INTRODUCTION:

Q235B carbon steel bar is a kind of ordinary carbon structural steel, which contains elements such as carbon, silicon, manganese, sulfur, and phosphorus in its chemical composition. It has good strength and toughness, and good machinability and welding performance. Q235B carbon steel bar is widely used in construction, machinery manufacturing, mining equipment, bridges, and ships.


2. APPLICATION:

The advantage of Q235B carbon steel bar is that its price is relatively low, and it has excellent machinability and welding performance, which is easy to be processed into various shapes and sizes of parts. It also has good mechanical properties and corrosion resistance, which can meet the requirements of various applications.

The production process of Q235B carbon steel bar generally includes steel ingot melting, continuous casting, rolling, forging, and heat treatment. Among them, rolling is the main production process, which can produce bars of various specifications and shapes.
