According to ISO plan for dimension series bearings are provided with two digit numbers. The first number indicates the width series 8, 0, 1, 2, 3, 4, 5 and 6 in order of increasing width. The second number indicate diameter series 7, 8, 9, 0, 1, 2, 3, and 4 in order of ascending outer diameter of bearing. Thus bearing number SKF 2015, 3115 and 4215 shows bearings belonging to different series with 75 mm bore diameter but width is increasing. SKF 2015, 3115 and 4215 shows width is increasing ascending outer diameter of bearing same bore diameter 75 mm. (i.e. 15 × 5)

Bearing Identification
In this question, we are given three ball bearings identified as SKF 2015, 3115, and 4215. We need to determine which characteristic of the bearings is common and which one is increasing or decreasing.
Options:
a) Bore is common but width is increasing
b) Outer diameter is common but bore is increasing
c) Width is common but outer diameter is decreasing
d) Bore is common but outer diameter is decreasing
Explanation:
To solve this question, we need to understand the basic parameters used to identify ball bearings. These parameters include the bore (inner diameter), outer diameter, and width of the bearing.
1. Bore: The bore is the inner diameter of the bearing, which determines the size of the shaft that can fit inside the bearing.
2. Outer Diameter: The outer diameter is the overall diameter of the bearing, including the outer ring.
3. Width: The width is the thickness or height of the bearing, which determines the space it occupies.
Analysis:
Let's analyze each option given in the question to determine the correct answer.
a) Bore is common but width is increasing:
This option implies that the inner diameter of the bearings remains the same, but the width increases. Therefore, the bore is common among all three bearings, and the width is increasing.
b) Outer diameter is common but bore is increasing:
This option states that the outer diameter of the bearings remains the same, but the bore increases. Therefore, the outer diameter is common among all three bearings, and the bore is increasing.
c) Width is common but outer diameter is decreasing:
This option suggests that the width of the bearings remains the same, but the outer diameter decreases. Therefore, the width is common among all three bearings, and the outer diameter is decreasing.
d) Bore is common but outer diameter is decreasing:
This option indicates that the inner diameter of the bearings remains the same, but the outer diameter decreases. Therefore, the bore is common among all three bearings, and the outer diameter is decreasing.
Conclusion:
After analyzing all the options, we can conclude that the correct answer is option 'a' - Bore is common but width is increasing. This means that the inner diameter of the bearings (bore) remains the same, while the width increases.
