Easier Set-Up For Trunnion Style Actuation Solutions

Easier Set-Up For Trunnion Style Actuation Solutions

TRD now offers mountable trunnion supports for 1½” to 8” bore trunnion mounts. The TB-1000 support will take all 1½” to 5” bores, and the TB-1375 support will fit 6” and 8” bores. Trunnion blocks are available in aluminum and stainless steel constructions.

All supports feature IGUS® “High-Load” bearings as standard. These bearings are made of T-500 composite which provide over ten times the strength of bronze bushings for heavy duty performance and long life. T-500 is rated for intermittent food and wash down applications.

Trunnion supports can be used with all NFPA mounts MT1, MT2, and MT4, as well as TRD solid one-piece steel trunnion styles SMT1 and SMT2. (See TRD Bulletin 07-04 for additional information on solid steel one-piece trunnions.)

All trunnion blocks are in stock and available for immediate order. Contact factory for delivery for large orders or special requirements.
