B3W Actuators
The B3W features a robust integrated and enclosed bearing design for the toughest environments.
Tolomatic’s B3W is a linear belt driven rodless actuator series that has a enclosed carrier support bearing design that provides long life and high load capability. The bearings and belt are protected by a stainless steel dust band that provides a IP44 rating against dust and debris. The B3W is the ideal choice for tough environments, especially those with high amounts of particulate and require long operating life.

- Stroke lengths up to 574 in (15.6m)
- Travel speeds up to 200 in/s (5 m/s)
- IP44 rating against dust and debris
- Auxiliary carrier and dual wraparound carrier options available for increased load capability

The Dual 180˚ carrier requires its own proprietary tube supports and foot mounts. See dimensional information. Breakaway torque will also increase when using the Auxiliary carrier or the Dual 180˚ carrier options. When ordering, determine working stroke and enter this value into the configuration string. Overall actuator length will automatically be calculated.
Deflection Considerations: In applications where substantial Mx or My moments come into play, deflection of the cylinder tube, carrier and supports must be considered. The deflection factors shown in the Load Deflection charts on the following page are based on cylinder mounted with tube supports at minimum recommended spacing. If more rigidity is desired, refer to the Auxiliary or Dual Carrier options.
*Loads shown in table are at minimum “D” dimension, for ratings with longer “D” dimension see graphs in B3 Catalog 3600-4176
