High efficiency Bevel Ball Linear Actuators from Joyce/Dayton are the
original mechanical linear actuators designed for near-continuous duty
operation. BB Series linear actuators provide higher speeds and less heat
generation than other mechanical linear actuators, with more precise
positioning and repeatability than hydraulic cylinders.
Featuring spiral bevel gear driven ball screws, BB Series linear actuators
provide efficiencies up to 86%, high duty cycles, travel speeds to 48 FPM
and static capacities up to 100 tons. They carry a J-10 life cycle rating
with fully predictable service life expectancy.
BB Series linear actuators are ideal for either single operation or multiple
linear actuator systems. Motorized versions are available; for precise
positioning Bevel Ball linear actuators can operate with stepper or servo
motors and other variable speed drives. Other options include limit
switches, encoders, geared potentiometers, direct drive and reducer mounts,
protective boots and left hand threaded screws.
Bevel Ball linear actuators also act as a miter gear box, simplifying
multiple linear actuator systems and reducing cost.
Bevel Ball linear actuators come in translating screw (shown), and rotating
screw (keyed for traveling nut) designs. A threaded end is standard; load
pad, clevis, plain and special ends are optional.
Note: BB Series linear actuators are not self-locking, and will lower under
load. A motor brake or other external locking system is required.
