As the cable carrier moves (cycles), the pins and holes in the link connections will wear or the no-back-bend limiting portion will wear, causing sag in the unsupported length portion (see the figure to the right).

This will result in the product being determined as having reached the end of its service life when it is no longer possible to guarantee protection of the cables/hoses and stable operation of the cable carrier.

This determination is made when the smaller of 1 or 2 below is reached.

Unsupported length sag limits (guideline)

1.10% of unsupported length

2.Cable carrier bending radius (R) amount

(ex.)

Unsupported length ：
500mm(⇒500mm×0%=50mm)→Sag amount limit (guideline): 50 mm

Cable carrier bending radius ：R55

■Should the cable carrier become broken, cracked, or otherwise damaged due to deterioration caused by age, the cable carrier is determined to have reached the end of its service life.

Cable carrier may reach the end of its service life relatively quickly in the following cases.

• 1.High acceleration/deceleration or operating frequency
• 2.Presence of wear caused by abrasives such as dust.
• 3.External vibrations.
• 4.Poor installation.
