In order to understand and investigate remaining amount of lubricant, after the sampling, to a good wash b [...]

  • Premature aging of rolling bearing analysis

    Premature aging of rolling bearings will cause the device to shut down, is now combined with the author's motor maintenance practices, describes the experience of preventing premature aging of rolling bearings. Causes of premature aging of rolling bearings: fits tight, poor lubrication, installation is not pollution, strong vibration, material fatigue, corrosion and so on.  1. tie too tight  When forced into the inner ring of the bearing shaft, t [...]

  • Grease failure analysis of abnormal SKF bearing vibration phenomenon

    There is a close relationship between the failure of lubricating grease SKF bearings and bearing working conditions, in which the most important is speed and temperature, single row deep groove sealed ball bearings, the grease filling amount of free space of the 1/4 bearing, SKF bearing speed n=3000 rpm, relationship of grease under no load condition and the service life the outer ring of the bearing temperature.SKF bearing grease in the bearing [...]

  • Clearance of bearing box and shaft and SKF bearings

    1, standard typeInstallation method of bearing box with a clamping ring and the fixing plate.Install the SKF bearings can cause bearing deformation by the positioning screw, should try to avoid.2, flange typeMounting flange linear bearing, and bearing inside the hole surface precision matching must be accurate.3, adjustable type (small type)The bearing and the bearing box opening is vertical, can get the circumferential direction uniform preload. [...]

  • The vehicle mounted SKF bearing inspection after

    The vehicle mounted SKF bearings, not rashly driving, need to check and to the following:1, try with the hand of a rotating shaft SKF bearing assembly, observe the following:1) whether the rotation system with collision or interference with the fixed parts,2) the rotation system is the axe stable flexible block, no loosening, pill and moving phenomenon;3) end SKF bearing inner ring is reliably conflict in the shaft shoulder end surface, which is [...]

  • Plus loads of SKF bearing failure analysis

    Rolling bearing in using process in the due to itself quality and external conditions of causes, its hosted capacity, and rotating precision and wear performance, will occurred changes. Dang SKF bearing of performance indicators below using requirements and cannot normal work Shi, bearing block on occurred has fault even failure, bearing once occurred failure, accident situation Hou, machine, and equipment will will stopped go, appeared features [...]

  • SKF bearing selection and use

    1. the choice of bearing type: bearing type is generally determined by the user's technical staff according to the conditions of use of the products and choose load for SKF bearings. Principal business personnel to understand the actual load is related to the selected user SKF bearings conform, if the bearing does not meet the requirements, you should advise the customer as soon as possible a new election model, but unless a special product in se [...]

  • Resolution SKF bearing the heat of internal lubrication technology

    Loss of SKF bearings for various reasons, all the design and manufacturing process of influencing factors are associated with bearing losses, bad judgment to parse. But under normal circumstances, generally can be used from both factors and internal factors considered and analysed.Loss of SKF bearings using factors mainly refer to installation and adjustment, maintenance, maintenance, repairs necessary to meet technical requirements. Installation [...]

  • Impact of SKF bearings on precision

    Typically, the axis is based on two bearings in radial and axial support, known as the locating bearing side of SKF bearings, which accommodate both radial and axial loads, fixed relative axial displacements between shaft and housing. The other side called the free end, only take radial loads, axial can be relatively mobile.Locating bearing shaft and housing are fixed and must at the same time, a more appropriate bearing radial bearing is subject [...]

  • SKF bearing basic machining process

    In the middle of practice, I learned that in real-world production and Assembly process, a group of the same type of bearing with a circulation card operation products. Circulation cards are printed on the products of the processing operation. When a bearing in the vehicle during the processing, circulation of this card, in skilled hands, the lathe when he finished the procedure, he stuck in the appropriate form, sign with your own name, this mea [...]
