Ace Glass 8065-64 Bearing Trubore, Economy, 45/50, 19mm

Self-aligning three-piece bearing. Complete consists of inner Trubore glass bearing, nylon bushing with FETFE O-Ring, and threaded adapter. Unique design eliminates costly replacement since inner bearing will spin if shaft binds, or will self-align at O-Ring seal in the event the motor is slightly cocked. Inner bearing and bushing can be used with any joint size.
