Webof failed bearings. The first bearing fails after about 30⋅ 10 6 revolutions, and the last one after 1,800⋅ 10 6 revolutions. The result is a factor of 60 from the first to the last! The L 10 life-time in this case— where 10% of the bearings failed and 90% are still working— would be about 120⋅ 10 6 revolutions. This Web20 nov. 2003 · Reduce the load on the bearing from 1165 Lbs to 925 lbs. This would result in keeping the original 6311 bearing but it now would be rated at 50,000 Hrs. B) Change in bearing size due to increased machine reliability: For a two bearing machine the L10h rating required to achieve 90% overall machine reliably is 95% X 95% = 90.3%. For the …
WebDeep groove ball bearings are versatile, self-retaining bearings with solid outer rings, inner rings and ball and cage assemblies. These bearings with their simple design, high resistance and low-maintenance, are available in single-row and double-row designs, as well as sealed and unsealed. Webeight bearings, and assume further that each of these eight bearings has a minimum calculated base L-10 of 200,000 hrs, very comfortably over the 166,440 hr target. That means the L-10 system life (finding the bearing that shows the prescribed evidence failure) is as follows: • L-10 system = ((1/L 10A) 3/2 + (1/L 10B) 3/2 + …(1/L 10n)
WebExample: A 100lb fan running at 1200RPM requires a 40,000 hour life. The Cr/P factor is 14.2. Multiplying that factor by the weight of the fan (14.2×100) will provide you the minimum required capacity of the bearing, in this case 1,402lbs. A bearing with a capacity larger than this will provide you with the 40,000 hours required. WebThe basic formula for calculating bearing L 10 rating life is: where: C = Dynamic Capacity (dN or Lbs) P = Equivalent Bearing Load (N or Lbs) N = Rotating speed in RPM. e = 3.0 for ball bearings, 10/3 for roller bearings.
