Improved Transfer Arm Heads for Sidel Blow Molders

Transfer arm heads carry the grippers that move preforms and bottles between the oven, the blowing wheel and the exit. Worn heads cause gripper instability, misloads and dropped bottles. UM's improved transfer arm heads are machined instead of cast, lighter, and built to last longer than the OEM heads.

What UM Improved

• Machined from aluminum instead of cast: stronger and about 20% lighter.
• Ball bearings replace the bushings. Bearings wear much more slowly than bushings, and as they wear they do not cause the gripper instability that worn bushings do.
• Replaceable striker plate and spring holders.

Rebuild Instead of Replace

On the OEM cast head, damage to the striker plate, the spring holders or the spring means replacing the whole head. The UM head can be rebuilt with a kit, so you only replace the worn parts. UM also supplies maintenance and rebuild kits for Universal biaxial transfer arm heads on SBO 6 to SBO 20 machines.

Ordering Transfer Arm Heads

Send the machine model and series, whether the head is quick-change or not, the OEM part number if known, and a photo of the installed head. Check the grippers and cam followers at the same time, since worn parts there also affect transfer stability.
