LOW COST, HIGH EFFICIENCY ACTUATOR TYPE VLA
THK’s Type VLA Actuator has fewer components and a lower overall cost, by using a THK LM Guide for its base. Long-term cost savings are also realized through the Type VLA’s incorporation of patented Caged Technology, a QZ Lubricator, and electro-mechanical components. The VLA’s electro-mechanical components offer improved energy efficiency, as well as cleaner and quieter operation. Contamination from lubricants, audible noise and damaging friction are greatly reduced.
TY SERIES OF HIGH SPEED LINEAR ACTUATORS
THK’s new TY Series Linear Actuator is designed to reach super high speeds of up to 5 m/sec. (16.4 ft./sec.), and accelerations up to 5Gs. Integrated with THK’s own Type SHS LM guide, as well as the QZ lubricator, the TY Series operates long-term and maintenance- free. The TY Series features a compact cross section. Meeting the demands of servo applications, THK’s new actuator provides standardized planetary gearboxes in 3:1, 5:1 and 9:1 ratios for optimum load inertia matching. Utility hardware is offered to allow for the easy construction of multi-axis systems, as well as to facilitate a variety of drive input shaft configurations.
INCREASED LOAD RATINGS WITH NEW LONG BLOCK TYPE SRS-N LINEAR MOTION GUIDE
THK’s new Type SRS-N features a longer block with block body consisting of resin molding for reduced weight and an increased load rating and moment capacity. Type SRS-N increased block lengths start from size 9 to 15. The dynamic load rating for the Type SRS-N starts at 3.48 C (kN),while static load ratings start at 3.34 Co(kN). Featuring patented THK Caged Technology, the Type SRS-N performs with smooth, quiet motion.
NEW DOUBLE-ROW TYPE RW ROLLER RING DELIVERS INCREASED RIGIDITY IN A COMPACT BODY
THK’s Type RW Double-Row Roller Ring features compact, yet highly rigid construction. The double-row roller structure at 45° and integrated inner and outer rings of the Type RW result in 20 to 30 percent higher rigidity than competitor models. The Type RW’s use of small rollers reduces differential slip and therefore the torque required for rotation is small. Installing the Type RW is easy due to the inclusion of mounting holes on the inner and outer rings. Housings and presser flanges are not required, and few assembly parts are needed. Design configuration is flexible per customer specifications.
