First, the design features (A) assembly installation: the outer ring made of split, you can easily adjust the bearing radial clearance to the ideal value, without using packet assembly method that can achieve high accuracy. The shaft is also very easy to install, without additional adjustment of other devices, simplifies machine structure (B) processing is easy: With the middle of adjustable links, so that the machining tolerance band can be greatly relaxed,

Lubrication of the bearing performance of imports can be divided into the following areas:1, first of all imported bearings of the various parts of lubrication, reducing friction and wear imported bearings 2 to the import of rolling contact bearings often form a proper film surface, to extend the import of bearing fatigue life;3, taken away by imported bearings lubricated internal friction or other reasons due to the heat generated;

A: angular contact ball bearings feature:  1. To face configure line towards the load bearing polymer bearing axis. Axial load carrying in both directions, although each is only by a bearing (or series bearing) load. Rigidity of this configuration is not back to back arrangement so high, is not suitable for the overturning moment. 2. To configure the bearings back to back line towards the load bearing axis divergence.

One of imports properly installed precision bearings Installation of bearing products for imports for one-off installation up and pay attention to something, and if not installed, then the import will not long bearing life. So, we need the import the import bearings installed, you should know to install their own methods of imported bearings, so as to ensure that imported bearing damage during installation. Following me to introduce comprehensive check the accuracy of imports bearing installation method:

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,
