1 BCS/MCS Screw Drives OVERVIEW APPLICATION BENEFITS Moderate load carrying capabilities at an economical price Easily retrofittable and interchangeable Adjustable carrier and self-lubricating bearings for easy maintenance GUIDANCE SYSTEM A patented* adjustable carrier bracket transmits the load to the cylinder body, instead of the screw for true tracking, superior load support and controlled minimum friction load. Two self-lubricating Delrin bearing rods, pass force directly to the cylinder tube. Patented** Band Retention system uses a T-shaped elastomer strip bonded to a stainless steel band, inserted directly into the body housing forming a tight metal-to-metal seal for clean operation. * U.S. Patent No **U.S. Patent No STANDARD MOUNTING Mounting holes are provided on the underside of the cylinder heads. To mount, transfer the location of holes to the receiving surface. Drill mounting holes /32" larger than diameter of the mounting screws and attach securely with appropriate screws. ACTUATOR/MOTOR FACTORS Actuator's operating temperature range (4-3 F, 4-54 C) should take into consideration heat generated by the motor and drive, linear velocity and work cycle time. For large frame motors or small actuators, cantilevered motors need to be supported, if subjected to continuous rapid reversing duty and/or under dynamic conditions. AVAILABLE OPTIONS Tube Supports: Provide intermediate support of actuator body at the recommended intervals. They are designed to fit into the dove-tailed grooves running the entire length of the cylinder tube. Mounting Plates: Provide clearance height for motors and motor mounts when mounting an actuator on a flush surface. Mounted to the tapped holes in cylinder heads, they provide the means for top mounting access. Kits include plates and mounting screws. Floating Mount Bracket: Compensates for non-parallelism between the actuator and an external support/guidance system. These mounts should be used on independently-guided loads to eliminate actuator binding. Use of the Float Mount, adds.4" (.36 mm) to the backlash. Auxiliary Carrier: Increases rigidity, load-carrying capacity and bending moments Motor Mounting and Gearhead Reduction: In-line Motor Mounting This motor mounting option uses a spacer and coupler to join the motor to the actuator shaft. Reverse-parallel Motor Mounting These factory assembled configurations allow offset mounting of the motor to either side of, or below the actuator. Available in : or 2: drive ratios, they offer quiet, zerobacklash coupling of the motor to the actuator screw shaft. Gearhead Reduction Gearheads are available for applications requiring reduction for inertia matching or higher torque at lower speeds. High efficiency, single stage, true planetary gearheads are available in 5.5: and : ratios for reduction solutions with most Tolomatic NEMA 23 and 34 face motors. See page F-.

FRICTION FORCE LOAD WEIGHT (kg) BCS/MCS BCS/MCS5 BCS/MCS LOAD WEIGHT (lb) FRICTION FORCE (N) LOAD WEIGHT (lb) BCS CARRIER BRACKET BOLT ADJUSTMENT (ALL SIZES) BCS 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 carrier bracket is adjusted properly. Some applications may require fine tuning of this adjustment to gain more lateral play or a higher degree of rigidity. In demanding applications, carrier adjustments should be done periodically. * CAUTION: Over-tightening increases drive torque of motor and drive.

PV LIMITS: Any material which carries a sliding load is limited by heat buildup. The factors that affect heat generation rate in an application are the pressure on the nut in pounds per square inch and the surface velocity in feet per minute. The product of these factors provides a measure of the severity of an application. P x V. x Speed. Thrust ((Max. Thrust Rating)) ((Max. Speed Rating)) ELECTRIC MOTION CONTROL FROM TOLOMATIC C-9
