The most effective way to guarantee the efficiency of your screw capper!
In the bottling industry a starwheel or timing screw are frequently used to help fill, cap or label bottles or cans. As the bottles are rapidly moved through the machine, sometimes a mis-feed or jam can occur causing damage to the starwheel or drive mechanism resulting in unscheduled maintenance and machine downtime. As productivity is scrutinized, and equipment is forced to run faster, the frequency and severity of jams increases. Overload clutches limit torque to a preset level and provide rotational timing for these applications. Select a Centric overload clutch as the torque timing device for your machine. Centric clutches from Boston Gear can increase productivity, allow higher operating speeds, and reduce your downtime costs. Boston Gear speed reducers and Warner Electric electropacks can also be incorporated to help maintain smooth, consistent performance in your bottling machinery.
For OEMs who provide rotary capping machines and beverage companies who use them, Warner Electric has a product for you… Warner Electric magnetic capping headset! Many capping headsets tighten caps with a pulsating or hammering impact magnetic torque which causes vibrations that lead to cap over-tightening, inconsistent removal torques, and accelerated wear on spindle assemblies and retention knives. Warner Electric capping headsets feature smooth torque magnetic technology with no pulsations. This smooth torque technology eliminates cap over-tightening and reduces variation in removal torque – improving end product consistency. This technology reduces shock on the system, enabling longer life of machine components, retention knives, and capping headsets. With models that are drop in replacements for most OEM models and design to withstand the harsh beverage environment, Warner headsets provide approximately twice the life of comparable OEM headsets – significantly reducing your rebuild costs!

Sure-Flex is a TB Wood's original! Sure-Flex Couplings utilize a rubber (EPDM or Neoprene) or Hytrel™ thermoplastic flex element (sleeve) to transmit torque and accommodate shaft misalignments. Sure-Flex couplings have exceptional torsional flexibility, and the
4-way flexing action absorbs virtually all types of shock, vibration, misalignment, and
end float. Sure-flex couplings are an excellent choice when low cost, high flexibility, vibration damping, and easy installation are primary concerns.
| • | Easy assembly |
| • | Spacer, bushed hub, and clamping hub designs in stock |
| • | Flexible design accommodates misalignment and protects equipment |

Dura-flex couplings "split-in-half" element design allows for easy element installation/ replacement without moving connected equipment or disturbing the shaft connection. Spacer design can accommodate a large range of shaft spacing with few parts. Patented design minimizes bond stress for long coupling life. Highly flexible and able to accommodate shaft misalignment while minimizing vibration and preventing damage to connected equipment.
