23rd September 2015 Bearing products 0 Comments



Deep ditch ball bearing (Deep Groove Ball Bearings) ( GB/T
276-1994)It is the most ordinary kind of type in rolling bearing. The deep ditch ball bearing of the basic model is by an outer lane, an inner circle, a group of steel balls keep the shelf constructed with one group. Uniline’s deep ditch ball bearing type code is 6.




Principle

The deep ditch ball bearing is used mainly for bearing the pure radial load, can also bear radial load and axial load at the same time. When it only bears the pure radial load, contact the angle as zero. When the deep ditch ball bearing has backlash of greater radial, have performance that angles are exposed to the bearing, can bear larger axial load. The coefficient of friction of the deep ditch ball bearing is very small, the terminal rotational speed is very high too, especially under the high-speed operation operating mode that the axial load is very large, the deep ditch ball bearing has superiority even more than the thrust ball bearing.




Type of the deep ditch ball bearing

Bring the sealed circle



Take the dustproof lid: Or the two-sided dustproof lid made of iron the form. Take the non- contact-type rubber to seal and enclose: Or too two-sided to exposed to sealed circle the form.



Take the contact-type rubber to seal and enclose: Form or two-sided to seal, enclose with the inner circle keeping in touch while being contact-type.



The outer lane tape stops moving the trough:



N: The outer lane tape stops moving the trough



NR: The outer lane tape stops moving the trough and stopping working up the ring.




Characteristic



The deep ditch ball bearing is the most representative rolling bearing, have wide use range. Suitable for the operation of the even extremely high rotational speed of the high rotational speed, and very durable, do not need to safeguard frequently. The coefficient of friction of this kind of bearing is small, the terminal rotational speed is high, simple in construction, the manufacturing cost is low, it is apt to reach and make precision higher. Size range and form are changed variously, apply to trades such as accurate instrument, electrical machinery, car, motorcycle and general machinery with low noise,etc., use the most extensive kind of bearing in the mechanical industry. Mainly bear radial load, can also bear a certain amount of axial load.



Choose and increase as compared to axial bearing capacity at the time of the great radial backlash, contact the angle as zero while bearing pure radial strength. When there is function of axial force, it is greater than zero to contact the angle. Generally adopting and pressing the wave shape keeps the shelf, the car makes the entity to keep the shelf, adopt nylon shelf too sometimes.



The deep ditch ball bearing is installed after on the axle, within the range of axial backlash of the bearing, can limit the axial displacement of axle or outer cover two directions, so can be making a reservation axially bidirectionally. In addition the bearing have transferring the intersection of heart and ability certain also, as 2 ‘ when the 10 ‘ of inclined relative to outer cover holing, can still work normally, but there is a certain influence on bearing life-span. It is mostly that the stencil plates press the wave shape to keep the shelf that the deep ditch ball bearing keeps shelves, the large-scale bearing adopt the car to make metal entity and keep the shelf more.




Application

The deep ditch ball bearing can be used in various common machinery, gearbox, instrument and apparatus, electrical machinery, household appliances, internal-combustion engine, traffic vehicle, agricultural machinery, machinery of the building, engineering machinery,etc..
