6.2.2 Timing Belt Replacement 

The timing belt is used in the robot for the driver system of the J2, J3, J5 and J6 -axis. Although the belt 

tension has been adjusted before the robot delivery, the timing belt will wear depending on the working 
conditions. The belt tension might be lower than the standard after operating for a long time. The timing 
belt should be periodically checked, maintained and replaced.   
(RA605-GB, RT605-GB replacement of the timing belt are similar, take RA605-GB as an example) 
 

 

Timing Belt replacement period 

    When the maintenance time is up to (six month), check the belt tension. If the tension is insufficient, 
adjust the belt tension. If the belt is excessively worn (wearing about half of the tooth width), the belt tooth 
is cracked or the belt is broken, replace the belt, but you are required to re-origin the points to correct the 
points.   
 
 
 
 
 

 

Belt Tension 

It is very important to keep proper belt tension. The belt tooth jumping will happen if the belt tension 

is too loose. If the belt tension is too tight, it will cause damage to the motor or bearing. Measuring methods 
of the belt by using fingers or tools are shown in Figure 6-2. When the belt is adjusted to the certain extent, 
you can feel the tension by your finger. If belt is too loose, it will vibrate; on the contrary, you will hear the 
sharp sound if it is too tight, and the belt is excessively worn. The sonic tension meter is used to measure 
the belt tension. The specifications and standard tension of belt are shown in Table 6-4.

When replacing the belt, the robot system origin may 
deviate. In this case, the position data must be rechecked if 
the origin is offset.  Please refer to section 4.1 for Zero-
position setting.
