Product Details
Deep groove ball bearings ; deep groove ball bearings are bearing the most common type . Basic deep groove ball bearing is composed of an outer ring, an inner ring, a set of balls and a group holding structure into . Deep groove ball bearing type has two kinds of single and double row deep groove ball structure also split seal and open two structures, open means bearing structure without seal , sealed deep groove ball into dust seal and oil seal. Dust Gland Material steel stamping , just play simple to prevent dust from entering the bearing raceways . Oil- proof seal for the contact , which can effectively prevent the grease within the bearing spillover . Single row deep groove ball bearing type code 6 , double row deep groove ball bearing code is 4. Its structure is simple , easy to use , is the production of the most common , the most widely used class bearings. Deep groove ball bearings mainly take radial load , but also to support radial load and axial load. When the only radial load , the contact angle is zero. When the deep groove ball bearings with a larger radial clearance , with angular contact ball bearing performance, can bear large axial load , deep groove ball bearing friction coefficient is small , limit speed is also high.
Silicon nitride, the chemical formula of Si3N4, is an important structural ceramic materials. It is a hard substance itself has lubricity and wear resistance, the atomic crystal; high temperature oxidation. And it is also resistant to thermal shock, the air is heated to above 1000 ℃, rapidly cooled and then heated rapidly, it will not shatter. It is precisely because the silicon nitride ceramics have such excellent features, people often use it to manufacture bearings, gas turbines leaves, mechanical seal rings, permanent mold and other mechanical components, in addition to hydrofluoric acid, which does not react with other inorganic acids (reaction equation: Si3N4 +12 HF ═3SiF4 ↑+4 NH3 ↑), anti-corrosion ability.

FAQ
a) How to prolong service life of bearings?
Accurate installation and using,alignment,timely monitor,re lubrication etc.
b) Reason for bearings failure?
Usually is incorrect using method,pollution,improper use of lubricant,damage happened
in installation and handing,also including installation error.according to the traces can
know the reason why is failure.
c) How to choose bearings?
Analyse mechanical device and use conditions.clear the requiremment of
bearings.select type of bearings,select distribution way of bearings.selet dimensions of
bearings,select installation method of bearings.
d) When select bearings specifications,what you need to consider?
The precision of the bearings(rotating precision,dimensional tolerances)internal
clearance and preload bearing material and heat treatment.structure of cage and material.
e) Payment method,packing way,transport method,time of delivery? T/T,PAYPAL,WESTERN UNION,L/C Tube,box,carton,pallet, By sea,by air 3-15days after receipt of payment.
