Parker Pneumatic HBC, HBT, HBR Series

Vertical Eccentric Load Capacity

HB Series units mounted vertically will have the same Eccentricity Eccentricity
eccentric load capacity regardless of orientation. The graphs
provide maximum load capacity for an eccentric mounted
load on a 4" stroke cylinder. The load is assumed to be
mounted at the face of the tooling plate.
Note: Actuator life may vary depending on the severity of
the following variables:
• Acceleration
• Velocity
• Vibration
B

EXAMPLE:
An HBT15 with ball bearings carrying
an eccentric load with an eccentricity
distance of 15" would have a load
capacity of 40 lbs. Guided Cylinders Actuator Products
