TT SERIES ROTARY INDEXER


The TT series Rotary Indexer compliments our line of RT and RTX fixed rotary indexers to allow us to accurately size our customer’s rotary indexing table application. The TT series fills in the gap where our RTX and RT series fixed rotary indexers may be slightly large or too small for a specific application. The Motion Index Drives TT Series fixed rotary indexer ranges from the smaller TT075 up to the TT315. With exception to the TT315, the standard TT Series rotary indexing tables have aluminum housing and flame hardened steel cams. The TT Series is manufactured with a fixed number of stations from 2 stations up to 108 in some models.

TT125 Indexing Table for Medical Manufacturing
Features
- 90-Degree Indexing: Capable of indexing at 90 degrees in a very short index time.
- Aluminum Housing: Durable aluminum construction for reliability.
- Steel Rotating Top Dial: Provides sturdy performance during operations.
- Tapered Roller Bearings: Utilized on the input shaft for enhanced stability.
- High Capacity Central Top Dial Bearing: Ensures smooth and efficient operation.
- Accuracy & Repeatability: Standard accuracy of +/-30 arcseconds and repeatability of +/-15 arcseconds.
- 3 Phase AC Gearmotor: Equipped with a 24VDC brake for efficient index time of ~0.5 seconds per 90-degree motion.
Functionality
The TT125 Indexing Table was engineered to meet the high demands of medical manufacturing, particularly in response to the COVID-19 pandemic. It allows for rapid production of medical-grade face masks by indexing at 90 degrees swiftly and efficiently. The integration of a 3 phase AC gearmotor with a 24VDC brake ensures an index time of approximately 0.5 seconds for each 90-degree motion, making it ideal for high-volume manufacturing environments. Its robust construction and precise engineering contributed to its effectiveness in producing the necessary quantities of face masks, thereby aiding in the prevention of COVID-19 spread.

Custom Trunnions with TT251 Fixed Cam Indexers
Features
– TT251 fixed cam indexers allowed for infinite positioning and index angles.
– Complete trunnion assembly with frames and risers.
– The system can utilize any motor type required by the customer, including AC motors with encoders, servo motors.
Functionality
The TT251 indexers were custom-designed with special cam profiles and output follower wheel, to achieve an output rotation specific to the application. The system uses oversized cam followers that always remain engaged with the cam profile, ensuring smooth, high-precision rotation during the welding process. Despite its capability to handle high loads, the system was extremely compact relative to its inertial load capacity, allowing for space-saving in tight automation setups.
