The journal surface is hardened as a rolling surface, and the bearing is pressed into the seat hole without axial positioning.

Zirconia ceramic bearingAll ceramic bearings have the characteristics of anti magnetoelec.tric insulation, wear and corrosion resistance, oil-free self lubrica-tion, high temperature and cold resistance. They can be used in ex-tremely harsh environments and special working conditions. Theferrule and rolling element are made of zirconia (ZrO2) ceramic ma-terial, and the retainer is made of polytetrafluoroethylene (PTFE) asthe standard configuration.Generally, glass fiber reinforced nylon66(grpa66-25),special engineering plastics (PEEK, Pl), stainlesssteel(AlSl SUS316,SUS304),brass (Cu), etc.

The outer ring double guard (or double lock ring) with cage needle roller bearing NA, NKI type, can be installed respectively inner ring and outer ring (with lock ring, a full set of needle roller and cage), high speed, divided into single and double row two. Such needle roller bearings with inner rings may be used if the shaft cannot be used as a raceway, i.e.

There are several types of 7000C (∝=15°), 7000AC (∝=25°) and 7000B(∝=40°). The lock of the bearing is on the outer ring, generally the inner and outer rings can not be separated, and can withstand the combined radial and axial load as well as the axial load in one direction. The ability to bear axial load is determined by the contact Angle, and the contact Angle is large, the ability to bear axial load is high.

Single row angular contact ball bearings mainly used forundertaking combined load both from radius and axle andalso for pure axle load,rotator speed is high.Material of bearings is choosed on refining bearing steelGCr15 (100Cr6，SUJ2,S2100) and other type of bearingsteel,balls are adopting GCr15 (100Cr6，SUJ2,S2100) orceramic. The bearings are classified as 7000C (15°)70000AC(25°)、7000B (40) in accordance with theircontact angle,other bearings with different contact angular areavailable on request.New domestic modelsOld domestic modelInner diameter (mm)Outer diameter (mm)Width(mm)Cr(kN)Cor(kN)G

Engineering Machinery Bearing have a large carrying capacity and are suitable for supporting structures with limited installation dimensions.The surface of the journal is hardened as the rolling surface, and the bearing is fitted into the seat hole with a press fit, and there is no need for it to be axially positioned.The bearing should be injected with an appropriate amount of grease before installation.Usually, no relubrication is required after assembly (BK type bearings are used in the support of the journal without the protruding end, the end face is closed for sealing, and can withstand

The sliding bearing seat is composed of an upper cover, a base, a split bearing bushing (aluminum bronze) and mounting bolts, which mainly bear radial load. Easy to use, no need to install bearings. The load-free part of the inner surface of the bearing bush is provided with an oil groove, and the lubricating oil flows into the gap through the oil inlet hole and the post groove.

I.

Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis, which means that they are designed to accommodate combined loads, i.e. simultaneously supporting radial and axial loads.The axial load carrying capacity of angular contact ball bearings increases with increasing contact angle.

Product Description:In some high-performance automotive components, such as suspension system components for high-performance sports cars or off-road vehicles, chassis reinforcement, etc., 5456 aluminum rods can be used in manufacturing.

(1)Linear motion bearing is a kind of low-cost metal for producing linear motion system, which is used for infinite stroke cylindrical shaft.. Because point contact ball bearing with shaft, so using the load is small.  (2) the flange linear bearing can be divided into: round flange type, method type, elliptical flange type, guided round flange, guiding method, guide the elliptical flange type, extended round flange type.(3)According to the specification is divided into two series of LM and LME series.

Thrust roller bearings are used to bear axial and radial combined loads based on axial loads, but the radial load shall not exceed 55% of the axial load.

Bearing seat is an important part of supporting and fixing bearing, and its processing technology design directly affects the accuracy, life and reliability of bearing seat. Bearing housing is usually made of high-strength alloy steel or cast iron to meet its requirements for high load and wear resistance. Secondly, the design of the process flow is the core of the bearing seat processing technology. Usually, the processing of the bearing seat includes casting, roughing, finishing, heat treatment, surface treatment and other links.

Inch taper/tapered roller bearings belong to separable bearing, as the outer ring, also called cup, is separable and easy for assembly.

Product Description:The thickness specifications of CSB galvanized steel coil are diverse, and the thinner thickness is suitable for some products that are more sensitive to weight and cost and do not need to bear too much pressure, such as internal shielding covers of electronic equipment, small packaging boxes, etc.

Product Description:The 6061-T6 Aluminum Pipe is a heat-treatable aluminum alloy known for its excellent mechanical properties, good corrosion resistance, and high strength-to-weight ratio.

The main role of automobile hub bearing is to load and provide accurate guidance for the rotation of the hub, which is a very important component to bear both axial and radial loads. The traditional automobile wheel bearings are composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance adjustment of bearings are carried out on the automobile production line.

The seal is an important protective part of the flange bearing, which can prevent dust, water vapor and other impurities from entering the bearing inside, while maintaining the stable state of the grease or lubricating oil inside the bearing to improve the service life and performance of the bearing.Generally speaking, flange bearings have the advantages of simple structure, easy installation, large carrying capacity, good wear resistance, etc., and are widely used in all kinds of industrial machinery and equipment, such as wind turbines, agricultural machinery and metallurgical equipment.

Iko tapered roller bearings have high load bearing capacity and wear resistance. Because of the conical roller design, the bearing can share the load evenly when bearing heavy loads, and the bearing capacity is effectively improved. At the same time, the use of high-quality materials and advanced manufacturing technology to ensure the bearing's wear resistance and extend the service life.Iko tapered roller bearings have high rotation accuracy and running stability.

Product Description:ASTM A36 carbon steel plates are used in the manufacture of mechanical parts such as bases, brackets, etc.

First of all, one of the characteristics of FAG deep groove ball bearings is a simple structure, consisting of an outer ring, an inner ring, a steel ball and a cage. This simple structure makes the installation and maintenance of deep groove ball bearings more convenient and fast.Secondly, the bearing capacity of FAG deep groove ball bearings is large and can withstand both radial and axial loads.

NTN deep groove ball bearing is a common rolling bearing, widely used in various mechanical equipment and industrial fields.
