Product Characteristics
Deep groove ball bearings from the four basic components, which are in raceway (inner), outer raceway (outer ring), and Ball Cage. Under normal circumstances of operation, within the raceway, outer raceway and ball bearing load, while maintaining separation of aircraft for the ball and play the role of maintaining stability. Single row deep groove ball bearings to the heart of simple structure, both inside and outside the ring is not isolated and easy to use, such as precision instruments, low noise motors, automobiles, motorcycles, woodworking machinery, textile machinery shaft, and mining machinery, electrical and mechanical equipment, plastic machinery, office equipment, medical equipment, fitness, defense, aviation, aerospace and sports equipment and general machinery, machine-building industry is the most widely used in a class of bearings. Mainly used to bear radial load, it can withstand a certain amount of axial load. Increase the bearing radial clearance, the thrust bearing has the heart of nature, can withstand large axial load. Such bearings may limit the axial movement in both directions. According to the size of clearance to allow, the outer ring relative tilt 8 '~ 16'.
Product Classification
At present, production DWCF Deep Groove Ball Bearings can be divided into the following types:
1, single row deep groove ball bearings
2, with dust cover of the single deep groove ball bearings
3, with dust cover, a separate ring of deep groove ball bearings
4, there are only moving the outer ring and stop ring groove single row deep groove ball bearings of
Single row deep groove ball bearings
General in the installation, sealing, with no special requirements for the components, such bearings can be used.
With dust cover of the single row deep groove ball bearings
Difficulties in the lubrication and inspection of lubrication difficulties and special conditions may be the use of such bearings. Dust cover with the gap between the inner ring. With dust cover on both sides of the bearing has been in the manufacture of lubricants into the right, so do not have clean installation lubricants and processing. Work in the allowed period of time do not have lubrication lubricant plus.
Ring with single row deep groove ball bearings of
The general framework of multi-ring rubber sealing ring of steel. It is a contact seal, dust cover and with the deep groove ball bearings compared. Waterproofing performance and better protection against dust, but large number of frictional resistance, a certain speed limit.
There are only moving the outer ring and stop ring groove single row deep groove ball bearings of
Ring can be used to do stop the axial positioning of the shell to simplify the installation.
Size range
Deep Groove Ball Bearings DWCF basic dimensions have been listed in the data table size
Diameter size range: 10mm ~ 1320mm
Diameter size range: 30mm ~ 1600mm
Size range Width: 9mm ~ 300 mm
Tolerance
DWCF standard deep groove ball bearings with a general level, all in line with the GB307.1.
radial clearance
DWCF standard deep groove ball bearings with C2, the standard (CN), C3, C4 and C5 level of internal space, all in line with the GB4604. Value of radial clearance forms detailed in the foreword, its value is not applicable to the installation and non-load bearing. Internal clearance greater than or less than the standard value of bearing can be manufactured in accordance with user requirements.
Cage
Deep groove ball bearings generally use steel or brass stamping Cage Cage entities. When the outer diameter of less than 400 mm, using steel stamping without Cage, code-named after the home, when the diameter is greater than 400 mm when the number of entities with Brass Cage not post code.
allows the angle error
Deep groove ball bearings allow the inside and outside the ring tilt angle of the relative error, according to the radial clearance, the following list
Allowed by the radial clearance angle
The basic 8 '
Group 3 12 '
Group 4 16 '
