Designed to accept a large selection of Hilliard thrusters. These thrusters include spring applied hydraulic released, spring applied pneumatic released, hydraulic applied spring released, and pneumatic applied spring released. The 400 requires a minimum disc diameter of 24" and is offered in 2 sizes to accommodate a 1" and 1-1/2" thick disc. The design of the caliper allows the user to quickly convert between right and left-handed designs eliminating the need for multiple part numbers.

The SH thruster is a failsafe thruster that is spring applied hydraulically released. The spring applied thrusters are offered in multiple sizes to meet the needs of our customers. The T400 SH thruster produces a maximum braking force of 8366 pounds at the maximum operating pressure of 1875 psi with a maximum pressure of 2250 psi. (This thruster is only to be used on the A400 caliper)

The Hilliard MK350 is an electromagnetic, fail safe caliper brake. Spring applied, electric released, it is suitable for holding duty and emergency for applications such as conveyors, elevators and cranes. Alternative mounting arrangement: pin mounting, base mounting horizontal and base mounting angle. 

The MK350 is capable of producing a maximum 350 LBF of braking force with up to 210 VDC release voltage and 100 VDC holding voltage. Mounted on pins allowing for axial movement, it has an optional manual release mechanism for a momentarily brake release with a standard open-end or socket wrench.

The Hilliard MK750 is an electromagnetic, fail safe caliper brake. Spring applied, electric released, it is suitable for holding duty and emergency for applications such as conveyors, elevators and cranes. Alternative mounting arrangement: pin mounting, base mounting horizontal and base mounting angle.
