What SBB TECH does

SBB TECH (에스비비테크) is a South Korean manufacturer of ultra-precision power transmission components, publicly listed on KOSDAQ under ticker 389500 and headquartered in Gimpo, Gyeonggi Province, with a reported headcount of 51-100 employees. The company specializes in three product families: (1) robot gear reducers, including the ROBO Drive Harmonic Type (SCSG/F, SSHG/F, SCSD, SSHD, SCSF-MINI series), the ROBO Drive RV Type, and a proprietary Saddle Worm (장고형 웜) reducer built on an enveloping worm and helical gear architecture; (2) precision bearings, notably the ROBO BEARING ultra-thin series (3/4" to 16" shaft diameters), ceramic, hybrid, and PEEK bearings, plus CMP (Chemical Mechanical Planarization) parts for wafer processing; and (3) robots and actuators, including the MR-05 modular positioning module, integrated ACTUATOR (RA) drive modules, and a semiconductor robot line (XP ROBOT, PRODUCER, VHP/VHP+, HP/HP+, wrist and buffer assemblies for Applied Materials-class systems such as ENDURA and CENTURA).

The company monetizes exclusively through B2B hardware sales of these components via direct sales and a quote-based inquiry system, with no publicly disclosed pricing and no third-party distributor channel. End customers cluster in three verticals: semiconductor equipment OEMs, robot and industrial automation manufacturers (with Korean Air and Hanwha Robotics referenced in inquiry logs), and aerospace/defense/medical precision equipment buyers. SBB TECH asserts it localized Korea's first domestic robot reducer in 2009 and that its bearings were the first Korean domestic bearings applied in overseas semiconductor production lines and defense applications, establishing a domestic-first-mover position. The business operates under the Songhyun Group (송현그룹) corporate umbrella and conducts annual shareholder meetings through its 26th fiscal term, consistent with a small-cap publicly listed supplier serving large industrial OEMs.

Core offering

SBB TECH designs, manufactures, and sells ultra-precision power transmission components including robot gear reducers (harmonic, RV type, and saddle worm types), ultra-thin precision bearings, integrated actuators, modular precision positioning robots (MR-05), and semiconductor manufacturing components (CMP parts, wafer-handling robots). The company sells these components directly to semiconductor equipment manufacturers, robot manufacturers, and industrial automation companies, with Korea's first domestically localized robot reducer launched in 2009.

Product overview

SBB TECH (에스비비테크) is an ultra-precision power transmission product specialist that developed Korea's first domestically-produced robot gear reducer in 2009. The company offers three main product lines: (1) Robot Gear Reducers including ROBO Drive [Harmonic Type] with multiple series (SCSG/F, SSHG/F, SCSD, SSHD, SCSF-MINI) and ROBO Drive [RV Type] for precision motion control; (2) Robots including MR-05 modular robot for factory automation, ACTUATOR integrated drive modules, and specialized semiconductor robots (XP ROBOT, PRODUCER, VHP/VHP+, HP/HP+, WRIST series) for wafer handling; and (3) Precision Bearings including ROBO BEARING ultra-thin series, CERAMIC BEARING, HYBRID BEARING, PEEK BEARING, CMP parts, and specialty ceramic components. The products serve semiconductor manufacturing, robotics, aerospace, defense, medical equipment, and factory automation industries.
