UCF215 Pillow block bearings

UCF215 Pillow block bearings Before 1990, China has been using the former Soviet Union’s completely numerically represented rolling bearing code method, which is very different from the international common bearing code method represented by English letters and numbers.
The basic code of the old standard bearing is composed of seven Arabic digits, and the prefix code can be added to the front of the code, and the supplementary code can be added to the back.
Seven digits from the right is the first digit, one and two digits indicate the bearing inner diameter, for example: 00 is 10MM, 01 is 12MM, 02 is 15MM, 03 is 17MM, 04 is an integer multiple of 5, 09 means the inner diameter is 45MM. Large inner diameters that cannot be expressed by two digits are marked by numbers directly after /. For miniature bearings with an inner diameter of less than 10MM, the first digit directly indicates the inner diameter.
