SNFA bearings are normally packaged in individual boxes, even when they belong to a bearing set. In this case, boxes are grouped together. Marking is with labels applied to each of the boxes. The label bears the following information:

• bearing set designation
• grease type (for SNFA greased bearings)
• packaging date
• actual contact angle (for single Universal bearings only)

Boxes are cardboard and are marked with the SNFA trade name and the description "Precision Bearings." The box contains bearing mounting instructions (in four languages).

Bearings with ceramic material balls or with Chromex� 40 rings are contained in boxes bearing a red or yellow label with the wording "CERAMIC" or "CHROMEX�40."
