Under usage conditions where moment loads are applied, such as vertical use with cantilever support, several times to over a dozen times the load acts on the linear bearings, which can lead to early failure. To address this issue, the 'U Ultra Series' has been developed through years of research. It is compatible with almost all of our linear bearing series, and since the outer dimensions remain unchanged, it allows for an ultra-long lifespan that is 18.5 times longer than conventional products, leveraging our accumulated experience and processing technology without the need for design changes. 【Features】 ■ Achieves an ultra-long lifespan 18.5 times longer than conventional products ■ Reliable performance even under harsh usage conditions ■ Compatible with almost all of our linear bearing series ■ No design changes required as outer dimensions remain the same *For more details, please refer to the PDF document or feel free to contact us.

The "Ozack MF Series" is a linear bearing that eliminates the need for grease replenishment, thereby reducing maintenance costs. It features special seals all around, excelling in dust and oil supply, and the newly developed seal structure significantly reduces grease leakage. When combined with CG (clean-compatible grease), it is suitable for clean environments; with VG (vacuum grease), it is suitable for vacuum environments; with HG (high-temperature and low-temperature grease), it is suitable for high and low-temperature environments; and with FG (food equipment grease), it is ideal for use in food equipment. 【Features】 ■ The newly developed seal structure significantly prevents grease leakage. ■ Lubrication performance is improved and can be maintained over a long period. ■ Rust-resistant types are standardized, making them suitable for use in corrosive environments. ■ The special seals have functions for retaining and supplying lubricating oil, as well as preventing foreign object intrusion. ■ The incorporation of grease and improved sealing performance results in quieter operation. *For more details, please refer to the PDF materials or feel free to contact us.

Introducing the G series that fills and supplies the appropriate amount of grease!! Achieving approximately twice the durability compared to standard products. In a reciprocating bearing mechanism, the rolling elements temporarily stop when moving back and forth, changing direction in the reverse direction. At that moment, the speed of the rolling elements temporarily drops to zero, causing the oil film to break and resulting in a slip phenomenon, which negatively affects lifespan. The G series, which fills and supplies the appropriate amount of grease, is guaranteed by experimental data to have twice the durability of conventional products, providing higher reliability. We have prepared various environmentally friendly greases to accommodate a wide range of environments. *For more details, please refer to the PDF document or feel free to contact us.
