Share of machinery bearing the space and location, in the mechanical design, the general first determine the shaft size, and then, depending on the shaft bearing sizes. Axis is usually chosen small ball bearings, roller bearings, shaft selection. However, when the diameter of bearing in the machine direction is limited, then use needle roller bearings, special light and ultra-light series of ball or roller bearings;

1. On the installation site selection and requirements  Installation site should lathes, grinders and other machinery and equipment away from some distance. Site should be cleaned regularly to keep dry and clean, prevent iron filings, sand, dust, moisture into the bearings. 2. Test bearing type, ready to install tools Test bearing type, size, compliance with installation requirements and in accordance with the bearing structure with the various features and components,

(1) interior design ACD - contact angle of 25 degrees. B - contact angle of 40 degrees. CC - a contact angle of 12 degrees. CD - contact angle of 15 degrees. BE - contact angle of 40 degrees BE-type bearings, ball up, with glass fiber reinforced polyamide 6.6 cage. Double row angular contact ball bearings A - 90 mm outer diameter less than or equal bearing of standard design, are not equipped with the ball gap,

1, shaft parts and materials of rough(1) shaft parts of the rough Shafts can use requirements, production type, equipment condition and structure, using bar, forgings and other blank forms. Little difference for the outer diameter of the shaft, generally the main bar; The big difference for the outer diameter of the stepped shaft or major axis, are often used in forging, so that saves on materials and mechanical processing to reduce the workload,

Regular inspection of the bearings, bearings in the best condition for the maintenance is very important work, you can also find problems reflected. Bearing in use on the precautions and knowledge. First of all, we want to stress is to keep the NSK bearing lubrication and clean is very important. So when we check NSK Bearings should be obtained before cleaning the surface of NSK bearings, and bearing surrounding the demolition of parts.

The six types of ball bearings: 1. Three point contact ball bearing Single row angular contact ball bearings when subject to pure radial loads, each load of the ball by two contacts with a channel, but with little contact with the other channel. Under pure axial load, each ball with only one contact with each channel. Two. Locking counterbored ball bearing ball bearings Outer ring of a rib removed all or part of the groove-type ball bearings.

Spiral bearing three characteristics:1. The main advantage of spiral bearing outer ring can be reused many times, making the event as due to the damage caused by the impact of temperature and bending to its re-processing possible. In this case, bearing also need to be adjusted. Structural design of such structures, not only spiral package bearing the outer ring needs to be change, all the other bearing components can be used again.

Follow the method of Roller Bearing Mill, in the hollow shaft and the Roller Bearing installation form more unreasonable to use the factory mill operation in the future work to bring some disadvantages. To solve this problem, we offer you the mill the best hollow shaft Roller Bearing assembly installation method.  Industrial use of fine grinding mill with Roller Bearings have been widely in China to promote and save the power consumption,
