BC2 Pneumatic Band Cylinder

Product catalog summary

Features
The BC2 Solid Bearing Rodless Cylinder is equipped with auxiliary carriers for enhanced load and bending moment capacity, floating mounts for non-parallelism compensation, tube support mounts for intermediate support, foot mounts for end mounting, and shock absorbers for smooth deceleration and increased speed. Switches are available in Reed, Hall-effect, and Triac types with quick-disconnect couplers.

Performance
Designed for durability, the BC2 series includes adjustable cushions for end-of-stroke deceleration, a formed end cap wiper seal for internal protection, and a stainless steel sealing band for extended performance. The load-bearing carrier design ensures low friction and long wear, with an adjustable carrier bracket for easy tension setting.

Specifications
Models such as BC205, BC210, BC212, and BC215 are available, each with specific dimensions, maximum bending moments, and load capacities. Cylinders are built-to-order with stroke lengths up to 350 inches, available in inch and metric sizes.

Application Guidelines
Selection and application guidelines include carrier bracket adjustments, tube support requirements, and auxiliary carriers for increased load capacity. Regular adjustments and maintenance are recommended for demanding applications.

Ordering Information
Ordering codes are provided for each model, with options for different mounting and fastener configurations. Detailed specifications and 3D CAD models are available on the Tolomatic website.

Specifications

Switch Types: Open PNP, Open NPN, Mechanical Contacts.
Operating Voltage: Up to 200 Vdc, 120 Vdc, 120 Vac, and 5-25 Vdc.

Procedures

Installation: Ensure the notched face of the switch is oriented towards the magnet. Contact Tolomatic for specific actuator side requirements.
Wiring Diagrams: Provided for various switch types including Reed, Triac, and Hall-Effect switches.

Performance

Shock Absorbers: Optional for rodless cylinders to increase lifespan and application range. Two types available: standard and adjustable.
Velocity vs Load: Graphs provided to determine final velocity based on load.

Guidelines

Application Requirements: Compile data such as available pressure, load weight, orientation, velocity, and stroke length.
Cylinder Selection: Use force vs. pressure charts to select appropriate cylinder size.
Load and Bending Moments: Consider the effect of bending moments and use auxiliary carriers if necessary.
Internal Cushion Capacity: Consult cushion data charts to ensure proper velocity and load handling.
Tube Support Requirements: Determine based on load weight and support distance.

Recommendations

Lubrication: Use dry, filtered air and consider external lubricators to extend service life.
Consultation: Contact Tolomatic for unconventional applications or selection assistance.

Specifications and Guidelines

Lubrication: Pneumatic actuators require a constant supply of oil lubricators, with a minimum of 1 drop per 20 standard cubic feet per minute. In systems with water, double the lubrication rate. Use non-detergent, 20cP @ 140˚F 10-weight lubricant for optimal performance between +32˚ to +150˚F (+0˚ to 65.5˚C).
Sanitary Environments: Use "Food Grade" lubricants with ORAL LD50 toxicity ratings of 35 or higher, such as Multitherm® PG-1.
Velocity Calculations: Differentiate between final and average velocity for rodless cylinders. Use 2x average velocity if final velocity cannot be calculated directly.

Application Guidelines

Cushion Needle Adjustment: Adjust cushion needles for smooth deceleration. Consult Tolomatic for proper adjustment.
Filtration: Use dry, filtered air (10 Micron or less) to prevent moisture-related issues.
External Lubricators: Optional but can extend actuator life. Ensure constant supply to avoid premature wear.

Service Parts and Ordering

Service Parts: Includes foot mount kits, shock field retrofit kits, and repair kits. Specify stroke length when ordering repair kits.
Switch Ordering: Various switch types available, including Reed and Hall-effect, with specific configurations for different models.

Ordering Configurations

Model and Mounting: Options include BC2 Band Cylinder and metric mountings.
Stroke Length and Bore Size: Specify desired stroke length and bore size when ordering.
Auxiliary Carrier: Options available with or without piston, specify "D" distance between carriers.

Critical Notes

External Lubricators: May wash away factory lubrication; maintain constant supply.
Shock Absorbers: Ensure air cushion is disabled for proper performance.
Compatibility: Not all codes are compatible with all options; consult Tolomatic for guidance.

BC2 Solid Bearing Rodless Cylinder PERFORMANCE BC2 THEORETICAL FORCE vs PRESSURE BC2 CARRIER BRACKET BOLT ADJUSTMENT ABT BC2 carrier bracket adjustment bolts should be adjusted to suit each individual application, depending on the degree of rigidity required. A good starting point is to tighten the nut on the bolt until there is no lateral movement of the bolt. Then, equally tighten each nut on the carrier bolt while moving the carrier by hand along the length of the stroke. When all lateral play in the carrier is eliminated and free movement along the length of the stroke is maintained, your...
