Sep 18, 2012 Type SBKH features re-circulation structure, where balls are picked up in tangential direction and lead-angle direction by end caps, that accommodates high-speed operation at DN value of 130,000. THK Caged Technology lends to smooth motion and minimized noise, while motorized drive facilitates maintenance and promotes energy conservation, machine control, and positioning accuracy. Available screw shaft diameters range from 83–120 mm.

Caged Ball LM Guides delivers low-waving, rigid performance.

THK America, Inc.    Schaumburg, IL 60173 5340
Sep 17, 2012 Available in 5 models with LM rail widths from 30–60 mm, Type SPR and Type SPS LM Guides feature 8 rows of raceways, small diameter balls, and extended length blocks. Ball deformation is minimized, which promotes rigidity, while number of balls reduces amplitude of rolling element. Also included, THK Caged Technology eliminates need for frequent lubrication and fosters long-term, maintenance-free performance. Resulting rigidity and low-waving performance promote equipment accuracy.

LM Guide features lightweight design.

Aug 13, 2008 Designed with cold drawn hollow rail and aluminum block, Light LM Guide enables high-speed operation. Unit includes hardened steel raceways and THK Caged Technology, which employs synthetic resin cage with patented curvature that cradles each ball and separates it from next one. Spaces between rolling elements retain grease and act as lubrication system for long-term, maintenance-free operation.

Linear Guide Ball Bushings are optimized for smooth motion.

THK America, Inc.    Schaumburg, IL 60173 5340
Jul 30, 2008 LG bushings employ rotation prevention function, where 4 rows of circular arc grooves are arranged on shaft, to ensure precision movement. Product is dimensionally interchangeable with linear bushing, as outer tube has same OD. Since outer tube and shaft are interchangeable, combination of outer tube and shaft may be selected. Tube OD ranges from 8-15 mm, with tolerances from 0 to -0.011, while tube lengths range from 12-30 mm, with tolerances from 0 to -0.2 and shaft ODs from 4-8 mm.

Compact Ball Screw is optimized for high speeds.

THK America, Inc.    Schaumburg, IL 60173 5340
Jul 18, 2008 SBK Ball Screw employs THK Caged Technology, which promotes smooth operation as well as long-term, maintenance-free operation while also preventing collision noise between balls. Recirculation structure, where balls are picked up in tangential direction, and lead-angle direction by end caps makes this product suited for high-speed operation at DN value of 130,000. Models are available with screw shaft ODs from 15-32 mm and nut diameters from 38-58 mm.

Miniature LM Guide utilizes caged ball technology.

THK America, Inc.    Schaumburg, IL 60173 5340
Jul 17, 2008 Available in heights from 6-6.5 mm, block widths from 12-17 mm, and block lengths from 14.2-19.4 mm, Model SRS5M/WM employs synthetic resin cage with curvature that cradles each ball and separates it from next one. Spaces between rolling elements retain grease and act as lubrication system. With low particle generation, guide is suitable for precision equipment applications, including medical, semiconductor equipment, and measuring instruments.

Linear Actuator targets clean room environments.

THK America, Inc.    Schaumburg, IL 60173 5340
Jul 17, 2008 Featuring corrosion-resistant, maintenance-free design, Model CGL15N/CGL20N includes seal mechanism and full size cover for minimized particle generation. THK Caged Technology employs synthetic resin cage with curvature that cradles each ball and separates it from next one. Spaces between rolling elements retain grease and act as lubrication system. Offering high-speed capabilities, CGL15N/CGL20N is compliant with ISO 14644-1 Class 4 at 2,000 mm/s.

Linear Motion Products suit variety of applications.

THK America, Inc.    Schaumburg, IL 60173 5340
Sep 07, 2006 Linear Motion Products utilize ceramic rails, blocks, and balls, contributing to non-magnetic characteristics and expanding range of applications. Ceramic components, as well as use of titanium stoppers and resin circulation parts, result in lightweight overall product and eliminate possibility of corrosion. Ceramic products are strong enough for chemical environments and suitable for high-temperature applications.

Compact Roller Ring is designed for rigidity.

THK America, Inc.    Schaumburg, IL 60173 5340
Sep 07, 2006 Type RU Roller Ring features double-row roller structure and integrated inner and outer rings that contribute to design rigidity. Use of small rollers minimizes differential slip and torque required for rotation. To facilitate installation, product features mounting holes on inner and outer rings. Housings and presser flanges are not required, and few assembly parts are needed. Design configuration is flexible per customer specifications.
