The designs and profiles shown in the part numbers, written as each brand writes them, with the number of part numbers: Lz (3), HMS5 (2), HMSA10 (2), Lx (2), and CRW1 (1).
Sizes are in millimetres: d is the diameter of the shaft the lip runs on, D the diameter of the housing bore the seal is fitted into and h its width.
Two seals with the same size are not necessarily the same seal: the lip design, the dust lip, the spring, the materials and the operating conditions they accept depend on the design and the brand. That is why we quote by part number: send us the part number shown on the seal, the box or the drawing, or the size together with the design and material you need.
If the part number can no longer be read, measure the shaft, the housing bore and the width of the old seal, and look the size up in the seals-by-size index: each size with a page lists all its part numbers.
