Ball Race & Concealed Bearing 

Architectural Grade Full Mortice Hinges

Ball bearing hinges have become the industry standard in many commercial and institutional applications. The ball race comprises hardened chrome alloy bearings and a (type 1008) steel sustainer for vertical support. A plated steel or stainless steel non-rising pin is included for lateral support. 

The CB concealed bearing system is a revolutionary concept in bearing construction and materials developed by our manufacturing partners at Stanley. It eliminates metal to metal contact between knuckles by creating its own bearing surface between the washer and the sleeve. As the stainless steel washer extends into the sleeve it eliminates metal to metal contact between the pin and barrel resulting in a
smooth, quiet operation superior to that of a ball bearing assembly.
