New from THK, the Type SHS-LE integrates the global standard THK Type SHS LM Guide with a THK linear encoder (linear position sensor). This combined model allows for compact machine designs that require less assembly time. THK’s Type SHS Caged Ball LM Guide performs with high speed and precision. Each row of balls is arranged at a contact angle of 45°, enabling the SHS to be used in all directions.
Featuring high-speed performance and load capacities that exceed existing full ball standards, THK’s new Type BSM Ball Screw is ideal for use in machine tools. The Type BSM utilizes a newly developed circulation structure and a large lead to meet high-speed performance demands. The DN value is 170,000, contrasted with 130,000 in conventional products. The unique groove design and double groove structure of the Type BSM improve load capacity, and meet the requirements of machine tool applications.
THK America, Inc.’s new Roller LM Guide Type HRX is designed to meet the demands of a variety of applications and environments. The Type HRX boasts a duplex face-to-face structure (DF Structure) and a full roller design for resilient performance in even harsh settings. Features include a highly rigid, yet simple structure, caged rollers and an extensive dust proof option.
For high rigidity during heavy loads, the Type HRX roller is designed to evenly distribute weight along the roller diameter and length. Roller performance is further enhanced through the incorporation of Caged Technology.
THK’s Caged Technology employs a synthetic resin cage with a patented curvature that cradles each roller and separates it from the next. The spaces between the rolling elements retain grease and act as a lubrication system for longterm maintenance-free operation. Smooth motion is achieved with the Type HRX, as the separation of balls eliminates friction and minimizes torque fluctuation.
Backlash-Free and High Accuracy Circular Motion
THK’s four-way equal load Type HCR Curved LM Guide provides backlash-free and high accuracy circular motion. It features four rows of raceways precision-ground on an LM rail and an LM block. LM blocks are arranged at the load points, allowing for large circular motion of 5m or greater and the capability of receiving loads in all directions. Multiple LM blocks can individually move on the same rail.
ENGINEERING MAKES THE DIFFERENCE
As the pioneer of the linear motion system and the patent innovator of Caged Technology, THK continues to be the preferred world leader in re-circulating, ball linear motion guide technology. When engineers select THK as their motion control partner, they get the benefit of THK’s industry-leading Global Engineering Team of Linear Motion Experts.
THK has developed a line of products that incorporate THK’s latest innovation – Caged Technology that separates rolling elements with a synthetic resin cage that retains grease and reduces maintenance costs.
Caged Technology offers these specific benefits:
- Quiet Operation that Minimizes Metal Contact. Collision noise between balls is eliminated by the ball cage resulting in quiet operation.
- Orderly Ball Movement. Since the balls are held by the ball cage in the form of a belt, they are aligned uniformly and move in a circulating manner. There is no skewing of the balls, while sudden variations in friction are also eliminated, allowing for stable movement.
- Original Cage Structure Exhibiting Excellent High-Speed Performance. The use of ball cages eliminates generation of heat caused by friction between balls resulting in excellent high-speed performance.
- Grease Holding Structure (Consecutive Grease Pockets) for Long-Term, Maintenance-Free Operation, and Long Service Life. Grease Pockets are provided consecutively over the entire ball circulation path to constantly lubricate the balls enabling long-term, maintenance-free operation, and Long Service Life.
