TSUBAKI (Tsubakimoto Chain) Power Lock TF Series

It can be mounted at any position on the shaft, and positioning and phase alignment can be done easily and freely.
After fastening, there is no backlash, and there is no need to worry about shaft discoloration or seizure due to vibration or impact.
The material can be used effectively without reducing the strength due to notches in the shaft such as keyways and splines.
Since it has a strong force against thrust, no measures such as retaining it are required.
Since it has a strong friction holding function after fastening, there is no risk of it loosening naturally, and you can use it with confidence.
Since the ratio of the inner diameter to the outer diameter is small, the boss outer diameter can be designed to be small.
The coaxiality when mounting the boss is excellent, and a guide for alignment is not required, so the boss hole can be straight, and the shaft is also straight, so troublesome processing is not required.
With a simple structure consisting of four parts: inner ring, outer ring, spacer and tightening bolt, it can be tightened strongly just by tightening the tightening bolt.
