Notes: Note 1: Type H1 is a flat ring without a notch. The data without parentheses is the size of a general narrow ring, and the data in parentheses is the size of a balanced sealed narrow ring; Note 2: Type H2 is the size of an unbalanced seal. The data without parentheses is the size of an unbalanced sealed narrow ring, and the data in parentheses is the size of an unbalanced sealed large end; Note 3: The unbalanced seal specification (without a notch) is the outer diameter. The data without parentheses is the size of the sleeve, and the data in parentheses is the size of the shaft; Note 4: The size of the ≤120 balanced seal shaft (or bushing) is consistent with the standard GB/T 6556 (mechanical seal type, main size, material and identification mark); for specifications ≥125, the size of the sleeve is in 10 steps, for example, the large end of φ125 is φ135, and the large end of φ130 is φ140; Note 5: The H1 type is a flat ring size, and the data in the parentheses, for example, the big end of φ125 is φ135, and the big end of φ130 is φ140. Note 6: The size of the ≤120 balanced seal shaft (or shaft with the specification ≥125 or more) has the sleeve size in 10 steps, for example, the big end of φ125 is φ135, and the big end of φ130 is φ140.
