how to calculate bearing size according to sleeve size
Answers
Answer:
Explanation:
Sometimes you may need to identify a bearing due to general wear and tear. Most bearing references now are laser stamped but these wear and rub off more quickly than the previous method, which was engraved deep in the bearing's metal .
Each bearing has an inside diameter, outside diameter and width diameter in that order. Most bearings are metric in size, but can also be imperial. On our site, each bearing shows its principal dimensions.
d = Inside diameter
D = Outside diameter
B/T = Width diameter
You can search for a bearing entering this information on the home page in the boxes provided.
Once you have identified the bearing's code some bearings come complete with seals or shields. This is known as the suffix in the bearings reference.
Bearing Example
6205 2RS1C3
The bearing type design that you need is a single row deep groove ball bearing with the following dimensions and suffix.
d = 25mm
D = 52mm
B/T = 15mm
Result = 6205
The bearing also has a seal either side of the bearing.
2RS1 = 2 Rubber seals
2RSR = 2 Rubber seals
DDU = 2 Rubber seals
2Z = 2 Metal shields
ZZ = 2 Metal Shields
