    جمبع انواع ال(bearing) ونوع الحمل الذي يعمل عليه بالصور

    Single Double
    Angular contact ball bearings are non-separable bearings that can accommodates radial loads and also thrust load in one direction. These bearings are suitable for use in high-speed applications and often matched with other angular contact ball bearings in. Various arrangements.
    most angular contact bearings have a contact angle

    both thrust ball and thrust roller bearings are bearings
    that are able to accommodate axial load only. Such bearings are not able to withstand radial loads. Generally, these bearings
    are not uses for high-speed applications?




    Spherical roller bearings are bearings that consists of a spherical outer race way and a cage assembly incorporating two rolls of barrel shaped rollers grounded into an inner ring. This type of bearings are suitable for high load applications and has self-aligning ability thus are able to compensate for shaft deflections and misalignment of the bearing seats. Such bearings have excellent capacity for both radial load and axial loads in both directions. These bearings are also suitable when there is vibration and impact load.



    Cylindrical roller bearings are able to support heavy radial loads and are suitable for high-speed applications. In general, such bearings are separable, enabling easy mounting and dismounting, except for the full complement design type that are not separable. There are many different types of roller bearings to choose from: NU, NJ, NUP, N, NN, NNU, NCF, NNF, …


    Taper roller bearings are made up of a roller and cage assembly called the cone and an outer ring called the cup. In most cases, the cup and cone are separable. This type of bearings has a high capacity for radial loads, axial loads and combined loads. Normally, taper roller bearings are used in pairs as such bearings can only transmit axial loads in one direction. There is a need to counter balance the axial loading by having another taper roller bearing symmetrically opposing each other. Both inch and metric sizes are available.

    Deep groove ball bearings are economical are the most widely used bearing type. Both single row and double roe deep groove are available and they can accommodate both radial and thrust load. Deep grove ball bearings are non separable self-alignment capacity is limited. Single deep groove ball bearings are for used in high-speed applications.

    Standard
    Self-aligning ball bearings are of the double row type, with a spherical outer ring raceway. Their Self-aligning capability allows them to compensate for misalignments, shaft deflections, and housing deformations


    Super Precision Bearings









    Super Precision deep groove ball bearings are design to achieve quiet running. They are therefore especially appropriate for application with high demand for ultra speed, quiet running and minimum vibration. Major applications for such bearings are in cold air units, starters for aircraft, vacuum pump, textile machines and machine tools.



    Ball screw support bearings have been developed especially for ball screw spindle support. They fulfilled the requirements for high accuracy, greater rigidity, low friction and also allows for quick position changes at high speed.







    Spindle bearings are single row angular contact ball bearings developed primarily for high-speed work spindles in machine tools. Spindle bearings differ from the regular angular contact ball bearings by their contact angle, degree of accuracy and cage design. Advantages offered by such bearings are higher rigidity, optimum rotational accuracy, excellent acceleration and low vibration output. Spindle bearings have a contact angle of either 15 degree or 25 degree.








    Typical applications of these very small bearings are: gyroscopes, measuring instrument and medical equipments. The special features of such bearings are low and consistent torque and quiet operation with minimal vibration at very high and low operation speeds.







    Cylindrical roller bearings are normally used in applications whereby there is a need for high capacity load ratings and when a high precision is required. They are mostly employed as the "loose" bearing in combination with the "fixed" spindle bearings.




    Needle Bearings





    Shell Type needle roller bearings are light-weight but are rated for heavy loads. They employ a shell type outer ring made from a thin special steel plate, which is accurately drawn, carburized and quenched to provide the minimum sectional height of the bearing. Three types of shell type needle bearings are available for selection according to customer's operating conditions. They are the caged type, the full complement type and the caged with seals type. The caged type has a structure in which the needle bearings are accurately guided by the cage and thrust rings. It is useful for applications at high-speed rotation. The full complement type needle roller bearings are suitable for heavy load application at low speed rotation.



    Machined type needle bearings are bearings with a small sectional height, high rigidity outer rings and a large load rating. There are two types of machined needle bearings for selection, the caged type and full complement types, both types available in metric and inch series. In addition, these bearings can also be supplied with or without inner rings.




    Needle roller cages are bearings for use in engine connecting rods. These bearings have superior performances proven in racing motorcycles and are widely use in high performance engines for small motor vehicles, outboard marines, and high-speed compressors as well as general-purpose engines.



    Combined Type Needle Roller Bearings are combinations of radial bearings and thrust bearings. Caged needle bearings are used as radial bearings and thrust ball or thrust roller bearings are used as thrust bearings. They are compact and economical and can be subjected to radial load and axial loads simultaneously. These bearings are widely used for machined tools, textile and industrial machinery.










    Capilube bearings are bearings that are lubricated with a newly developed thermosetting solid type lubricant. A large amount of lubricating oil and fine particles of ultra high molecular weight polyolefin resin are solidified by heat treatment to fill the inner space of such bearings. As the bearings rotate, the lubricating oil oozes out onto the raceway in proper quantity, keeping the lubrication performance for a long period of time.

    موضوع رائع
    بس ياريت لو تحط عليه تعليقاتك
    وتشرح للناس اللى داخله الموضوع ايه مميزات نوع عن الاخير
    يعنى لو هاركب رومان بلى لعمود دوار راسى لماكينه تخريم
    ياترى استخدم اى نوع؟؟؟؟؟؟؟؟؟؟؟
