Ordering and Guidelines
Guidelines for application, selection, and ordering assist in choosing the appropriate cylinder configuration. Service parts and maintenance recommendations ensure long-term performance.

Specifications
Detailed specifications for the BC3 series include dimensions, weight, maximum stroke length, pressure, and temperature range. The BC320 model is highlighted with both U.S. Standard and Metric measurements.

Procedures
Instructions for converting to single end porting and ordering auxiliary carriers are provided, emphasizing the need to determine the minimum distance between carriers.

Standards and Recommendations
Guidelines for tube support requirements and the use of configured CAD solid models to determine critical dimensions are included. It is noted that switches cannot be mounted on the same face as tube supports.

Performance Data
Charts illustrate the relationship between load and velocity, pressure and force, and load versus distance for various configurations. Theoretical force versus pressure data is also provided.

Dimensions and Models
Detailed dimensions for models BC310, BC315, and BC320 are provided in both inches and millimeters, along with diagrams for optional tube supports, foot mounts, and dual 180° carriers.

Key Features
The BC3 series features multiple port locations, including single end porting for flexible air hookup. The dual 180° carrier option increases load capacity and bending moments.

Ordering Codes
Order codes for different configurations, such as BC320, BC3M20, and BC3MM20, are listed, along with codes for optional features like tube supports and foot mounts.

Switches
Ten sensing choices, including DC reed and Hall-effect switches, are available, each with specific wiring configurations. Installation instructions emphasize correct orientation and caution against overtightening.

For intermediate support, tube support brackets can be mounted to the BC3 model. Made of black-anodized aluminum, the brackets are attached to the bottom and sides of the cylinder tube with rail nuts. The number of tube support brackets required and their placement depends on the overall length of the BC3 model and the load weight being moved and supported. Refer to the tube support data chart below. Note: Switches cannot be mounted on the same face of the actuator as tube supports.

DUAL 180° CARRIER The Dual 180° Carrier option may be used when load factors exceed those of a single carrier actuator. This option allows the load to be rotated 90° from the cylinder's carrier providing an additional load bearing mounting surface. NOTE: The Dual 180° Carrier option requires its own proprietary tube supports and foot mounts. See dimensional information below. Breakaway pressure will increase when using the Dual 180° Carrier option. BORE SIZE MAX.
