SLS/MLS Screw Drives OVERVIEW

1 SLS/MLS Screw Drives OVERVIEW APPLICATION BENEFITS Rigid, low-profile design is ideal for space-sensitive applications Consistent carrier tracking and long actuator life Wide base for ease of mounting. GUIDANCE SYSTEM Pre-engineered and fully enclosed the SLS slide guidance system consists of recirculating bearings on ground steel shafts, offering stability and endurance. Uses the same patented Band Retention system as the BCS 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. STANDARD MOUNTING Actuators are provided with T-nuts in the base of the cylinder body. Four T- nuts for the first 24 inches of stroke are standard. Two nuts are provided for each additional 2 inches of stroke. The SLS tube and work table accept /4" threaded square nuts (MLS, M6 threaded square nuts). 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 Mounting Plates: Provide clearance height for motors and motor mounts when mounting an actuator on a flush surface. Mount to either tapped holes in cylinder heads or to T-nuts, they provide the means for top mounting access. Kits include plates and mounting screws. 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. 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 Tol-O- Matic NEMA 23 and 34 face motors. For gearhead specifications and dimensions, see page F-. Switches: Reed, dc Hall-effect and ac TRIAC. See section I.

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= Thrust x V= Speed <. Max. Thrust Rating Max.
