how it works:

deep groove ball bearings mainly take radial load , but also to support radial and axial loads . when the only radial load , the contact angle is zero. when the deep groove ball bearings with a larger radial clearance , with angular contact bearings can bear large axial load , the friction coefficient is small deep groove ball bearings , the speed limit is also high.

bearing type :

1 , single row deep groove ball bearings

2 , with a dust cover single row deep groove ball bearings

3 , with a dust cover , a ring of single row deep groove ball bearings

4 , snap groove and snap ring on the outer ring of single row deep groove ball bearings

5 , ball gap of deep groove ball bearings

6 , double row deep groove ball bearings

in accordance with the deep groove ball bearing sizes can be divided into :

( 1 ) miniature bearings ---- nominal diameter size range of 26mm or less bearing ;

( 2 ) small bearings ---- nominal diameter size range of 28-55mm bearings ;

( 3 ) small and medium sized bearings ---- nominal diameter size range of 60-115mm bearings ;

( 4 ) the large bearing ---- nominal diameter size range of 120-190mm bearings

( 5 ) large bearing ---- nominal diameter size range of 200-430mm bearings ;

( 6 ) large bearings ---- nominal diameter size range of 440mm or more bearings.

installation:

deep groove ball bearing mounted one: press-fit : the bearing inner ring and the shaft so that a tight fit , the outer ring with the bearing hole is relatively loose fit , can press the bearing be pressed onto the shaft , then the shaft together with the bearing together into the bearing hole , press-fit the inner end surface of the bearing pad of a soft material of the fitting sleeve of metal (copper or soft steel ) ,bearing outer ring and bearing bore tight fit , while the inner ring and the shaft is relatively loose fit , the bearing can be pressed into the bearing hole , then assemble the outer diameter of the sleeve hole should be slightly smaller than the diameter of the seat if the bearing rings and the housing bore when the shaft is a tight fit , the outer ring is installed to the indoor coil and simultaneously pressed into the shaft and the housing bore , the assembly structure of the casing should be able to simultaneously close the end face of the charge and the outer ring of the bearing inner ring .

deep groove ball bearing mounted method two: heating with : heating bearings or bearing, using thermal expansion will fit into tight loose fit installation method is a commonly used method of installation and effort over this method is suitable for a large amount of interference . the bearing installation , the thermal loading of the bearing before the bearing or separable rings into the tank uniform heating 80-100 ℃, then taken out from the oil on the shaft as soon as possible , in order to prevent the cooling face and the inner shoulder fit is not tight , you can then tighten the axial bearing cooling . bearing bearing outer ring and light metal tight fit,use of heating and hot charging method bearing avoided with the surface by abrasion . when the tank is heated by the bearings, should be at a certain distance from the bottom grid network , or hung with a hook bearing , the bearing can not be put on the bottom to prevent the heavy impurities into the bearing , or uneven heating , the tank must have a thermometer , strictly control the oil temperature must not exceed 100 ℃, in order to prevent tempering effect , reducing the hardness of the ferrule .

processed form :

1,a multi- step process : general bearing production process takes 20 ~ 40 , and more than 70 channels .

2 , forming : work surface rotary bearing parts are molded surface , suitable for use molding processing.

3 , precision machining : the vast majority of the surface of the bearing parts to go through grinding, precision grinding size and geometry are in μm units .
