Cylindrical roller bearing the outer flange of the bearing mounted together

Wheel bearings are used in automotive axles for Cylindrical roller bearing and rotating at the hub of providing precise guidance components, both axial load and radial load, is an important part of the car load and rotation. Traditional automotive wheel bearing is composed of two tapered roller bearings or ball bearing combination, bearing installation, oiled, sealed and adjust the clearance is carried out in the car on the production line. Cylindrical roller bearing This structure makes it difficult in a car assembly plant, high cost, poor reliability, and maintenance car maintenance, but also the need for bearing cleaning, oiling and adjustment. Wheel Hub Bearing In standard angular contact ball bearings and tapered roller bearings developed on the basis, it sets bearing as a whole, with good assembly performance can be omitted clearance adjustment, light weight, compact structure, large load capacity, for can advance into the grease sealed bearings, seals and hub maintenance omitted from the outside wheel, etc., have been widely used in cars, and in the truck also has a tendency to gradually expand the application. History Car wheel double row cylindrical roller bearing  are used in pairs over a maximum single row tapered roller or ball bearings. With the development of technology, the car has been widely used car wheel unit. The growing scope and use of hub Cylindrical roller bearing unit has now developed to the third generation: The first generation is a double row angular contact bearing components. The second generation of the outer raceway for Cylindrical roller bearing a fixed flange bearing sleeve may simply be fixed with a nut on the axle. Makes the car maintenance becomes easy. The third generation wheel hub bearing units are using a bearing unit and ABS anti-lock brake system compatible. Wheel hub unit designed to have the inner flange and an outer flange, the flange is bolted to the drive shaft, the outer flange of the bearing mounted together.

slim section ball bearing of the larger temperature change

slim section ball bearing used in vibration. Them to press fit mounted to the shaft, eliminating the friction corrosion which may be caused by axial clearance is not tight, self-aligning bearing system can also be formed with good performance and reliability. Toroidal roller bearings can performance structure with smaller and lighter to achieve the same or better, for example in the planetary gear box. slim section ball bearing They simplify the bearing arrangement on the longitudinal axis of the larger temperature change. The use of this kind of bearing vibration are reduced, for example in the paper machine and fan. It is a long and slightly single row bearings symmetrical roller coronary. Bearing inner and outer ring raceway are concave in shape, Tapered bearing around the bearing center symmetric distribution. Thus the best combination of raceway characteristics, slim bearings load distribution in favor of bearings to reduce friction. slim section ball bearing with self-directed, regardless of whether the inner ring relative to the outer ring axial displacement and / or misalignment, roller is always in a uniform load distribution on the roller length position. It's a very strong load capacity, even in has to compensate for angular misalignment or axial displacement. So, bearing layout in the operation is reliable, extended service life.

Backing bearings is very important

The bearing arrangement includes not only the rolling bearing, but also with the bearing components related, such as the shaft and the bearing seat. A very important part of the lubricant is also bearing configuration, as lubricants to corrosion abrasion proof, so that the bearing can give full play to the role of. In addition, the seal is also a very important component, Backing Bearings the seal performance is very important for lubricant clean, Backing bearings keep clean the bearing service life have a profound impact. In order to design of rolling bearing configuration, Stainless steel turntable bearing need – select the suitable bearing type and Determine the appropriate size of the - bearing, But this is not enough. There are several other aspects to consider: - such as the other parts of the bearing arrangement proper form and design, - correct fit and bearing internal clearance or preload, - fixed device, Seal - proper, The type and dosage, lubricant, and - installation and removal methods. slim bearings Each individual will affect the performance, reliability and economy of the bearing arrangement. Work required depends on whether similar bearing matching experienced. In case of lack of experience, there are special requirements, or the need for bearing configuration cost and any other subsequent appearance to give special consideration, Backing bearings need to do more work, such as a more accurate calculation or test.

Why do so many industries need to Cylindrical roller bearing

Cylindrical roller bearing are widely used at present market is very hot, and in this process, the field of machine tools use some relatively wide. Scope of application: this bearing needle roller bearings are used for gearbox, motorcycle, automobile, Cylindrical roller bearing the small end of connecting rod. Gear. Because the cylinder temperature reducer, increase, so the bearing high temperature. With thin and long needle bearing roller (roller length is 3~10 times the diameter, the diameter is generally not more than 5mm), so the radial structure is compact, its diameter size and load capacity compared with other types of bearings at the same time, minimum diameter, especially for radial installation support results in limited size. full complement cylindrical roller bearing According to the use of different occasions, can be used without inner ring bearings or Cylindrical roller bearing and cage assemblies, the shaft neck surface and the surface of shell holes matched with a bearing directly as bearing inner and outer rolling surface, to guarantee load capacity and operating performance and have the same ring bearing, shaft or housing holes raceway surface hardness, the machining precision and the surface quality of bearing ring raceway and similar.

slim section ball bearing Classification and Features

(1) GE ... E Type: Single every outer ring, no oil tank. slim section ball bearing Can withstand the radial load and smaller axial load in either direction. (2) GE ... ES type: single slit outer ring, with oil tank. Can withstand the radial load and smaller axial load in either direction. (3) GE ... ES-2RS type, GEEW ... ES-2RS type: single slit outer ring, with oil tank, sides with a ring. Can withstand the radial load and smaller axial load in either direction. (4) GE ... ESN type: single slit outer ring, GE ... XSN type: slim section ball bearing double-slit outer ring (split outer ring), with oil tank, with snap groove on the outer ring. Can withstand the radial load and smaller axial load in either direction. slim section ball bearing But by the snap ring axial load to bear, its ability to withstand axial load is reduced. (5) GE ... HS type: inner ring with oil tank, double half of the outer ring, the wear and tear clearance can be adjusted. Stainless steel slewing bearing Can withstand the radial load and smaller axial load in either direction. (6) GE ... DE1 type: inner ring of hardened bearing steel, the outer ring of the bearing steel. When the inner assembly extrusion, with oil tank and oil hole. Inside diameter of less than 15mm bearings, no lubrication groove and hole. Can withstand the radial load and smaller axial load in either direction. (7) GE ... DEM1 type: inner ring of hardened bearing steel, the outer ring of the bearing steel. Crossed Tapered Roller Bearing When assembling extruded inner bearing into the bearing housing, the pressure on the outer ring of the bearing axial end ditch fixed.
