TM Series - Models TM21, TM26, and TM35

Our TM Series features a streamlined and compact design which allows for significant weight reduction without sacrificing durability or frame rigidity. We use tapered roller bearings in these models that require no periodic grease lubrication. No period lubrication assures reliable performance over time without the risk of efficiency loss or failure, unlike other machines where bearing lubrication is required and can be catastrophic when overlooked. The ™ series worm shaft, using the recommended geared machine oil, employs a unique design that protects the shaft. Models in this series are the TM-21, TM-26, TM-35.
