Grease-filled linear bearing "G Series"

Grease-filled linear bearing "G Series"

Achieve double the durability by sealing in grease!

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.

Technical Data: The Impact of Shaft Deflection on Lifespan

Technical Data: The Impact of Shaft Deflection on Lifespan

If there is significant deflection at the axis, the lifespan calculation of the linear bearing is determined by a formula.

If there is significant deflection in the shaft, it will affect the lifespan of the linear bearing. In such cases, the lifespan of the linear bearing will be calculated using a specific formula. This document includes methods for calculating the impact of shaft deflection on lifespan, as well as formulas for both "free support at both ends" and "fixed support at both ends" scenarios. Please make use of this information. [Overview of Contents] ■ Impact of shaft deflection on lifespan ■ Shaft deflection calculation formulas *For more details, please refer to the PDF document or feel free to contact us.
