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 select the load on the bearing. Principal business personnel to understand the user′s actual load are compatible with the selected FAG bearings, 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 select models are generally not a problem.
2, bearing clearance options: users at the time of purchase bearing usually only inform on what type, grade and rarely claim on clearance, operational staff must ask the conditions for use of FAG bearings, speed, temperature, combined with tolerance of the bearing of which are directly related to the choice of bearing clearance. At 3,500 rpm the motor speed below mostly CM clearance, such as a high speed motor requires a relatively large clearance. Bearing clearance after Assembly as large and cylindrical hole up in narrow and lead to a reduction, clearance reductions = interference x60% (bearing housing is aluminum). Before Assembly of the bearing clearance is 0.01mm, Assembly interference of 0.01mm, the bearing clearance is 0.004mm. In theory while bearing zero clearance status of noise and life to achieve the best, but in actual operation, taking into account issues such as temperature rise, bearing clearance after Assembly is 0.002mm-0.004mm better.
3, choice of grease: grease is generally chosen based on speed of FAG bearings, temperature, torque and noise requirements and other aspects to choose required business performance to various oil very well.
4, selection of bearing type a, b, c: FAG bearing lubrication can be divided into oil and grease. Oil-lubricated bearings are generally used bearings, grease lubricated bearings generally use rubber seals shields or seals. Dust cover for high temperature or use the good parts, seals-contact and non-contact sealed type sealed two-contact sealing, dustproof performance good, but starting torque, non-regulated braking torque is small, but good sealing performance, no-contact.
FAG bearing mounting surface and with parts of surface, such as scratches, rust, dust, grit, dust, and soil, a bearing installation difficulties, resulting in incorrect Assembly position; these attachments to form a second loss, easy to mount the bearing working surface with abrasive, affect the quality of Assembly. Therefore, install the front axle, bearing block hole of the shell surface, face, shoulders and connecting components such as bushings, washers, mating surfaces such as end caps, a careful inspection. If there is corrosion, use fine nail file nail file, polishing cloth, but also clears the bearing Assembly and connecting parts on the surface of the substrate.
