Extending Motor Bearing Life | Pumps & Systems
Dec 17, 2011· "If (and it''s a big if) ball bearings are kept clean and properly lubried, their average or L-10 life should be 3 ½ centuries-3,180,000 hours." We did the math and came up with an L-10 life calculation of 3,175,926 hours or 362.30 years that ten percent of those bearings will fail because of metal fatigue.

Motor Bearings, Not Just a Piece of Metal
2.5 Sleeve Bearings The bearing life of a Sleeve Bearing is practically infinite, provided that the operation follows the operating condition specified for this type of the bearing. Motors have sleeve bearings at both ends. The bearing on the D end is the guide bearing and means that it can tolerate a limited non axial force.
Motor Bearings: sleeve, unit, spherical, ball bearings
Sleeve bearings, under normal operating conditions, will last as long or longer than ball bearings. Bearing temperatures are a major factor in determining the useful life of a motor. The following are some typical expected life hours at various bearing temperatures. Do not substitute ball bearing motors for sleeve-bearing motors if noise will

Electric Motor Bearings
These bearings don’t require a cage and race in the same way that ball bearings do. Electric motor roller bearings are used for belted appliions with motors 150 HP and above. The surface of the cylindrical shape rolling elements helps to account for the high level of radial load that the belts put onto the bearings.
Electric Motor Ball Bearings Types & Options
Jun 29, 2016· Sealed Bearing. Generally used in smaller motor appliions. These limit the entry of contamination greatly. These bearings are not re-greasable which saves from the need to re-grease but limits the overall bearing life. These bearings have limited life spans and require replacement upon any signs of issues. Shielded Bearing

H-30 Service Life Service Life - Oriental Motor U.S.A. Corp.
The service life of a bearing greatly affects the service life of a motor. The service life of a bearing can be expressed in 2 ways: ① Grease life is affected by grease deterioration due to heat. ② Mechanical life is affected by rolling fatigue. In most cases, the motor life is estimated based on ① the grease life, since the bearing life
Follow these procedures when checking endplay in a ball
The reduction in L10h bearing life will be proportional to the amount of pre-load. By way of example, a .040” pre-load can decrease L10h bearing life to a matter of hours. Tip: When a stock motor is modified for a direct couple appliion, the DE roller bearing should be replaced with a standard ball bearing.

Plant Engineering | So, how long should bearings last?
Aug 09, 2013· The L 10 life is the age to which approximately 90% of bearings of a sufficiently large population under similar conditions will survive. The “10” in L 10 refers to the 10% of bearings that will not reach the L 10 life.. The life of a bearing should be approximately five times the calculated L 10 life (again, as a solid rule of thu, usually around eight to 12 years).
