It can be widely used in outdoor building structures, such as roofs, external walls, fences, etc., extending the service life of buildings and reducing maintenance costs.

Product Description:Q195 carbon steel coil due to its good plasticity, can be used to manufacture light steel keel, can be easily processed into various shapes of keel, and can withstand a certain building load.

Tapered roller bearings are separated bearings, and the inner and outer rings of the bearings are equipped with tapered raceways. This kind of bearing is divided into single row, double row and four row tapered roller bearings and other different structural types according to the number of rows of rollers installed. Single-row tapered roller bearings can withstand radial loads and axial loads in a single direction.

Product Description:Because of its strength and good plasticity, hot rolled low carbon steel coil can withstand various loads in building structures, and is widely used in the construction industry to make various building structural parts, such as steel beams, steel columns, roof trusses and so on.

Product Description:S320GD+Z Galvanized Steel Coils are engineered for superior strength and corrosion resistance. These coils boast a robust zinc coating that provides excellent protection against rust and atmospheric corrosion, making them suitable for a variety of construction and industrial applications where durability is key.

UBC tapered roller bearing is a kind of rolling bearing with tapered roller, the roller and raceway between the inner ring (cone hub) and the outer ring (cup) intersect at the cone half Angle on the outer surface of the cone, so that the bearing can bear a large load in the radial and axial direction. UBC tapered roller bearings usually include single row, double row and four row structures, which are widely used in automotive, mechanical equipment, aerospace and other fields.

Single course thrust ball bearings: consist of two washers with raceways and balls guided b a cage. Washers have flat seating surfaces, and that is why they need to be supported so that all balls can be evenly loaded. Bearings lift the axial load solely in one direction. They are no longer capable to lift radial forces.Double path thrust ball bearings: have two cages with balls between the central shaft washer and two houding washers with flat seating surfaces.

The important measure to reduce automobile fuel consumption is to design low friction torque hub bearings, and the main factors affecting the bearing friction torque is the type of bearing and preload, and the bearing seal accounted for a large proportion of the friction torque components. Therefore, improving the seal design to reduce the friction torque can significantly improve the performance of hub bearings.

Car hub bearings used to be the most used in pairs of single row tapered roller or ball bearings. With the development of technology, car wheel hub unit has been widely used. The use range and usage of wheel bearing units are growing, and it has now developed to the third generation:The first generation is composed of double row angular contact bearings.The second generation has a flange for fixing the bearing on the outer raceway, which can be simply inserted onto the axle and fixed with a nut.

The insulated bearing is a specially designed bearing whose internal structure can effectively isolate the external environment and prevent conductive and conductive heat. Insulated bearings are usually used in special industrial environments or in equipment requiring special protection.Structure composition: The insulated bearing is composed of an inner ring, an outer ring, a rolling body, a cage and a seal.

Product Description:Q215 carbon steel coil is one of the commonly used materials for manufacturing welded steel pipes. Through crimping, welding and other processes, carbon steel coils can be made into steel pipes of different diameters and wall thicknesses, which are widely used in water supply and drainage, gas transmission, heating pipes and other fields. It can also be used to manufacture various accessories in the pipeline system, such as elbows, tees, quads, etc.

Inner and outer ring design: The internal and outer rings of the insulated bearing are made of insulating substances or different treatment, so that the modern-day interior the bearing can now not be carried out via the internal and outer rings, so as to reap the impact of electrical insulation.Seal design: The seal format of the insulated bearing is strict, which can efficaciously forestall the infiltration of exterior media and preserve the insulati
