Most Frequent Causes of Bearing Failures


Most Frequent Causes of Bearing Failures
 
Did this bearing really fail again!? Here are a few reasons for bearing failure to consider when experiencing difficulty with your bearing:
1.     Inadequate Lubrication: 54% of bearing failures are due to the lack or excess of lubrication in the bearing. The bearing should have 20% to 30% lubrication.
2.     Improper Sealing: If you bearing is susceptible to contaminants, make sure it is sealed to protect it.
3.     Overload or Excessive Speed
4.     Damage from surrounding parts
5.     Improper mounting or mishandling
6.     Manufacturing defects.

Rusting and corrosion is oxidation of the steel


Rusting and corrosion is oxidation of the steel. by www.vxb.com This can cause pits on the surface of the rings and rolling elements causing the bearing to cease. What causes corrosion? Well, there are a few causes of corrosion: Ingress of water, condensation of moisture in the air, poor packaging/storage conditions, and handling the bearing with bare hands. To prevent rusting one must ensure proper storage and proper sealing mechanism. These measures will prevent corrosion during long periods of mom-operation.

Would you like a cone or cup?


Would you like a cone or cup? This bearing comes with both! This single-row tapered roller bearings has the capacity to carry radial and axial load in one direction simultaneously (cone + cup). The sliding motion between the inner ring and flange and the roller end is the primary heat generation source. They have optimized the design of this critical area to reduce heat build up. The featured 30219 bearing is a metric standard taper bearings and measures 95mm x 170mm x 34.5mm and is made of chrome steel. http://www.vxb.com/page/bearings/PROD/Kit7101

No one wants to be caged; unless you are a ball bearing!

No one wants to be caged; unless you are a ball bearing! There are 3 types of cages we offer, here at http://www.VXB.com. The first is the riveted steel cage. This cage is held together by rivets and it made of chrome steel or stainless, depending on the type of steel the bearing is made of. This type of cage is good for high speed applications. The second option is Nylon. The nylon cage is good for low friction. The third option is Bronze. Bronze cages are good for high temperature applications. A bearing with no cage is a full compliment bearing and that is usually found in high temperature bearings, the different Cage Options for a Bearing.

Walking the dog? Around the world?


Walking the dog? Around the world? Well none of these fun tricks would be possible without the help of this little Yo-Yo bearing. http://www.vxb.com/page/bearings/PROD/Kit1069 This particular bearing has ceramic balls which minimizes friction, making them perfect for the speed we often aim for in a yo-yo. Some of the yo-yo models it fits are Tamiya, Kyosho, Duncan, ProYo, Freehand, Turbo Bees, Cold Fusion. The dimensions are 5mm x 10mm x 4mm. The inner and outer races are made of chrome steel for durability. 5x10 Yo-Yo ceramic bearings.

Living in the hot life! 1,000ºF is what this little bearing handle.

 



Living in the hot life! 1,000ºF is what this little bearing handle. That is pretty hot if you ask me. http://www.vxb.com/page/bearings/PROD/HighTemperatureBearings/Kit18121 This bearing is made of Silicon Nitride races and ball bearings. Ceramic is non magnetic, non conductive, and produces the least amount of friction. You will notice, this bearing has no cage and that allows for the ball bearings to expand in the heat. The bearing needs to be used in an application with no vibration, light load on the bearing, and no heavy impact as the bearing is brittle. The featured bearing measures 8mm x 22mm x 7mm, 608 Full Compliment Ceramic High Temperature Bearing.

Highest Temperature: 1000 (degrees Fahrenheit) = 537.78 (degrees Celsius)

Not 1, but 2 rows please.



Not 1, but 2 rows please. Double row angular contact ball bearings are used for radial loads, and can also carry thrust in either direction. 
http://www.vxb.com/page/bearings/PROD/Kit8356 Their radial load- carrying capacity is not double the corresponding single row bearing, but is 1.55 times the single row bearing for a 20º contact angle and 1.47 times for a 30º contact angle. The featured bearing measures
35mm x 72mm x 27mm and is made of chrome steel. We offer a large selection of sizes in angular contact bearings, 5207ZZ Double Row Angular Contact bearing.

No washer needed here…when using a bearing with cage and roller assembly

 



No washer needed here…when using a bearing with cage and roller assembly, http://www.vxb.com/page/bearings/PROD/Kit8683 a separate raceway washer is not needed if the gear side is used as a raceway. This saves space and allows the bearing to be even more compact. If the bearing is placed in a housing, that will not allow the gear side to be used as a raceway, using an integrated bearing facilitates handling and mounting. Thrust bearings are often used in automobile drive trains, compressors, hydraulic pumps, machine tools, and industrial machinery.

    Bought this bearing to replace the front passenger side strut bearing on my 97 Geo Metro. The bearing came in the mail within a few days of placing my order, and it seems to be holding up well so far.... Eric, Burlington, VT

    Get a load of this…for the last 20 years


    Get a load of this…for the last 20 years, Nachi has had the highest load rating in the world! Bearing life is directly related to load ratings. A larger diameter roller relates to less stress, less stress relates to a longer bearing life. Stamped steel retainer coupled with floating aligning ring permits longer length rollers. All spherical roller bearings are heat stabilized so the bearings can operate to 400F with no reductions in bearing life.
