"RollerDrive(R)" is a positioner for factory automation that achieves high-precision indexing by completely eliminating backlash through a preloaded structure. Due to rolling contact, it maintains initial accuracy almost indefinitely. Maintenance other than oil changes is unnecessary, and the grease-lubricated version is completely maintenance-free. We offer a wide range of models, including the standard "RGV series," the large-diameter "RGR series," and the ultra-compact "MR series." 【Features】 ■ Zero backlash for high precision ■ Maintenance-free due to rolling transmission ■ Compact with orthogonal axes ■ Excellent stability allowing for high-speed positioning ■ Integrated output shaft bearings (RA/RU series) *For more details, please refer to the PDF document or feel free to contact us.

Are you facing any of these concerns when selecting a positioning device? - Unable to find a positioning device that can handle heavy loads... - Unable to find a product that can achieve stable positioning under uneven load conditions... The "Roller Drive RGV Series" is a rotational positioning device that achieves high durability and stable operation for applications with high and uneven loads. We have numerous implementation records for machines with a load mass of 50 kg or more and devices with a load inertia of 5 kg·m² or more. This is because the more stringent the load conditions, the greater the advantages compared to other mechanisms. Additionally, our unique zero-backlash technology enables the realization of high output torque with compact servo motors and extends their lifespan. We offer options for rust-proof, dust-proof, and waterproof specifications, as well as a wide range of reduction ratios and sizes. If you are interested, please feel free to download the materials or contact us. 【Features】 - Maintenance-free with grease sealing - Waterproof and dust-proof options available - Compatible with servo motors from various manufacturers - A wide range of reduction ratios and sizes available

The "Laura Drive RGV Series" is a rotational positioning device that achieves high durability and stable operation in drive units subjected to high loads and uneven loads. Do you have any concerns when selecting a drive unit? - I can't find a positioning device that can stably drive a large table... - It's difficult to shorten the takt time with a large table... This product has numerous implementation records for index tables with a table diameter of Φ600 or more and machines with a load mass of 50kg or more. It contributes to increased productivity through high-speed positioning of large tables and reduced running costs due to being completely maintenance-free. Additionally, our unique zero backlash technology enables the realization of high output torque and extended lifespan with small servo motors. We offer options for rust-proof, dust-proof, and waterproof specifications, as well as a wide range of reduction ratios and sizes. If you are interested, please download the materials or feel free to consult us. 【Features】 - Maintenance-free with grease-sealed specifications - Waterproof and dustproof options available - Compatible with servo motors from various manufacturers - A wide range of reduction ratios and sizes available

The SL series is a parts feeder that combines two movements—horizontal and vertical—using a cam to generate elliptical vibrations for transporting workpieces. While conventional electromagnetic feeders are affected by changes in the amount of workpieces, the SL series can provide stable feeding regardless of variations in workpiece quantity or load. It can accurately transport powders, which are typically considered difficult to handle. ■ Features - Compatible with a wide range of feeding speeds - Smooth transportation, minimizing damage to workpieces - Improved operating rate with consistent amplitude and high stability - Low noise and low center of gravity - Reduced maintenance work - Recoil elimination through a damping mechanism (DSU) ■ Applications Straight-line transportation of workpieces * It may be able to handle workpieces that are difficult to transport with other mechanisms. ■ Specifications 【SL25】Recommended chute length: 350mm, Recommended chute mass: 3kg 【SL90】Recommended chute length: 600mm, Recommended chute mass: 8kg 【SL200】Recommended chute length: 900mm, Recommended chute mass: 10kg
