Question

g 02-series a straight (cylindrical) roller bearing is subjected to a radial load of 20 kn. the life is to be 8000 h at a speed of 950 rev/min and exhibit a reliability of 0.95. what basic load rating should be used in selecting the bearing from a catalog of manufacturer.

Answer 1

To select the basic load rating for a 02-series roller bearing, use the formula: Basic Load Rating = (Radial Load × Life)/(Speed × Reliability). Substituting the given values, the basic load rating is 177.78 kN.

Step-by-step explanation:

In order to select the appropriate basic load rating for a 02-series straight roller bearing, we need to consider the given radial load, life, speed, and reliability. The basic load rating is a value that indicates the load capacity of the bearing and can be obtained from the manufacturer's catalog.

To determine the basic load rating, we can use the formula:

Basic Load Rating = (Radial Load × Life)/(Speed × Reliability)

Substituting the given values, we have:

Basic Load Rating = (20 kN × 8000 h)/(950 rev/min × 0.95) = 177.78 kN

Therefore, the basic load rating to be used in selecting the bearing from the catalog is 177.78 kN.
