Product Description

SPHERICAL PLAIN BEARING

Produced from:HGF

Introduction：

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.

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!

STK400 is structural steel,standards is JIS G3444 of carbon steel tubes for general structure.

Description

Galvanized pipes have a wide range of uses. In addition to oil and other low-pressure fluid pipelines, it is also used as oil well pipes in the petroleum industry, especially in offshore oil fields, oil heaters in chemical coking equipment, coal distillation, and oil washing converter pipes, bridges, etc. Pipe pile, mining tunnel support frame with pipe, etc. Developed countries in the world started to develop new pipes and continuously banned galvanized pipes.

Product introduction：

Galvanized steel pipe is divided into cold galvanized steel pipe, hot galvanized steel pipe, cold galvanized steel pipe has been banned, the latter is also advocated by the state can be used temporarily.

Application：

Hot-dip galvanized steel pipe is widely used in construction, machinery, coal mine, chemical industry, electric power, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, mining machinery, greenhouse construction and other manufacturing industries.Galvanized steel pipe Welded steel pipe with hot dip plating or electrogalvanized coating. Galvanized steel pipe can increase the corrosion resistance, prolong the service life. Galvanized pipe has a wide range of uses, in addition to the pipeline pipe for water, gas, oil and other general low pressure fluid, but also used in the petroleum industry, especially the oil well pipe, oil pipeline, chemical coking equipment of the oil heater, condensate cooler, coal distillation and washing oil exchanger with the pipe, and trestle pipe pile, mine tunnel support frame with pipe.
