This cumene process involves contacting, in an alkylation zone, a first benzene recycle stream and a propylene feed stream with an alkylation catalyst to form cumene. Each rolling bearing includes an inner race with a rolling bearing inner surface and an outer race with a rolling bearing outer surface. The first entity may be a client and the second entity may be a server. The chelated iron is preferably present in the range of about 0. A glass fiber package of the present invention includes a glass fiber aggregate which contains alkali-containing glass wool fiber having an average fiber size of 5 \u03bcm or less and containing 5% or more by weight of alkali metal oxide components is packed in a compressed state so as to give a form which is able to be handled as a freight where the bulk density is 80 to 135 kgm3.
