The TTR2 (Titanium Roller) AirBlock® has evolved from Harken’s successful line of Titanium Roller Bearing blocks. Lightweight and strong, these compact load-bearing blocks are 98% efficient, harnessing power other blocks lose to friction.
Titanium rollers handle bearing loads, while high-wear composite thrust bearings handle side loads for reduced maintenance.
Sideplates are 6061-T6 hardcoat-anodized aluminum for durability.
