Proper lubrication of KOYO bearings' anti-friction bearings is critical to their successful operation. For ordinary or sleeve type bearings, there are different principles in different practices. In order for the party to maintain anti-friction bearings, these principles must be understood and applied.
[a] size limit. KOYO bearings usually have limited installation space. In most cases, the shaft (or bearing inner diameter) is based on mechanical design or other design limitations. Therefore, the choice of bearing type and size is based on the inner diameter of the bearing. Therefore, the main bearing size table is based on the size and preparation of the diameter table in the international scope.
There are a variety of forms, preferably in the use of mechanical devices, designed to measure bearings (the purpose is to easily purchase the bearing, in which it is placed on one side, some bearing catalogue entry models, but some non-standard bearings in mainland China KOYO bearing size size China, no spot, futures will be very long, sometimes, let time to consider the choice of bearings and the capital after replacement) Bearing load, its properties apply to the bearing load, size, direction is constantly changing . Normally, the basic load rating is shown in the size of the table. However, axial and radial loads, etc., are also an important factor in bearing selection. When the size of the ball and needle bearings, needle bearings, usually have a higher load capacity and withstand greater vibration and shock loads.
[B], speed, KOYO bearing type, size, accuracy, cage, load, lubrication, cooling method and other factors determine the speed based on the promise. The table lists the precision bearings and greases in the lubricant scale, according to the agreed speed. Normally, deep groove ball bearings, self-aligning ball bearings and cylindrical roller bearings are used for high speed operation.
[C], KOYO bearing tolerances, dimensional accuracy and rotational accuracy of bearings are based on the International Organization for Standardization (ISO) and JIS scale. For high precision and high speed machinery, it is recommended to use 5 or more precision bearings, deep groove ball bearings, angular contact ball bearings or cylindrical roller bearings for high running precision and mechanical. Elastic deformation occurs when the contact pressure between the rigid body and the moving bearing raceway. Some machines require less elastic deformation. Has a small elastic deformation than a ball bearing roller bearing
[four], and in some cases, KOYO bearings pre-tightening to increase rigidity. This process is commonly used for deep groove ball bearings, angular contact ball bearings and tapered roller bearings with inner ring offset, shaft bending, shaft or housing tolerance changes, and inner and outer rings with errors that will result in eccentricity. In order to prevent excessive degrees, the eccentric angle of self-aligning ball bearings, self-aligning roller bearings, spherical bearings is a better choice. Voice frequency and torque, the production scale of moving bearings is highly accurate, and therefore, voice and torque are small. Deep groove ball bearings and cylindrical roller bearings combine low sound and have special requirements for low torque applications.
[5], installation and removal, some applications often need to be disassembled and installed to ensure testing and maintenance. Can be installed inside and outside, such as bearing ring: cylindrical roller bearing, needle bearing, tapered bearing combined in this occasion. Self-aligning tapered bore and self-aligning ball bearings in the cylindrical sleeve roller bearings also simplify the installation process.
