NSK bearings focused on the Assembly to control the height of the bearing. Due to high tolerances than radial bearings NSK bearing clearance tolerance is much more relaxed. So as long as the shaft washer or washer Raceway Groove height in the process of asking was assured that the bearing Assembly without matching, where you can assemble, meet requirements of separation and isolation of bearing parts can be exchanged.
For bearings, in addition to controlling the height of the Centre of the road and from the ferrule end face, other than to ensure total height of cylindrical roller bearings, but also controls the size of raceways are located at the Center diameter. To ensure tolerances of the contact angle, machining and testing of these are not in parts. When the requirements when the parts are guaranteed, bearing Assembly process was simple and smooth, which is why the part accuracy testing of thrust bearing instead of a finished product testing reasons.
1, the choice of bearing type: bearing types are generally determined by the user′s technical personnel by the conditions of use of products to choose and load bearing. Business personnel to understand the user′s actual load are compatible with the selected NSK bearings, cylindrical roller bearings do not meet usage requirements, should advise the customer as soon as possible a new election model, but unless special offers on select models generally do not have any problems.
2, bearing clearance options: users at the time of purchase bearing usually only inform on what model, grade, rarely on bearing clearance request, the business person must ask the bearings use conditions, speed, temperature, with the tolerance of the bearing of which are directly related to the selection of bearing clearance.
3, oil choice: choice of oils are generally based on speed, temperature of the bearings and torque, noise requirements and other aspects of selecting, require business to know about grease performance is.
4, selection of bearing type a, b, c: lubrication of cylindrical roller bearings can be divided into oil and grease. General is the choice of the form of oil-lubricated bearings bearings, grease lubricated bearings are generally use rubber seals shields or seals. Dust cover for high temperature or use the good parts, sealing-contact seals and two non-contact seal, contact sealing, dustproof performance large starting torque, small non-connecting sealing torque, good sealing performance of no-contact.
NSK bearings are separable pieces more needs of most small and medium bearing cage and ball form components, this required when assembling steel balls and cage pressure, pressure-cage type-related. For large bearings, some cage without pressure, all parts are detachable, cylindrical roller bearing packing should set binding and firm. Double direction bearings and accessories parts bearing a single column is very strong, machining tools, ear as needed for Assembly, this is the bearing of a point. Differentiation and bearing Assembly process.
