A massage system having a massage table, support members and a massage machine is disclosed. The massage table may securely attach to the massage machine by the support members. Attachment members that massage the user's body are preferably different roller type attachments of different sizes. Multiple rollers may be attached to the massage machine one at a time. A user may select from different massage treatment options by a control panel. The user may lie face down on the massage table and the massage machine will provide a soothing back massage corresponding to the option they chose.

Massage system

In pressure forming splines or teeth in the sleeve of a clutch hub and the like, a rotatable toothed mandrel and a pair of sliding toothed racks are offset relative to one another such that when the sleeve of the clutch hub blank is placed on the mandrel, a ring-shaped lip portion of the sleeve adjacent the open sleeve end is not intermeshed between the mandrel teeth and rack teeth and thus is not splined and such that a transition region between the cylindrical oil seal surface and the sleeve is splined. The clutch hub thus includes splines on the sleeve terminating short of the open sleeve end in an unsplined ring-shaped lip portion and extending at the other end contiguous with splines formed in the transition region between the oil seal surface and sleeve. A clutch hub can thereby be manufactured having, in combination, a longitudinal tooth taper (bellmouth) within required close tolerances, e.g., within 0.010 inch, preferably within 0.005 inch, and an oil seal surface with roundness within required close tolerances, e.g., within 0.005 inch.
