Universal Series TY

This belt drive actuator has a caged ball LM Guide combined with a lightweight and compact aluminum base.
Options such as a stainless steel cover, a motor bracket or a sensor make it useful for a variety of applications.

A maximum stroke of 4749 mm* is possible due to the belt drive method.
A maximum travel speed of 3400 mm/s is possible when an AC servomotor (rated rotational speed 3000 min.^–1) with a 3:1 reducer is used.

Maximum Travel Speed

Unit: mm/s

Model no.	TY20
Reduction ratio	1/3	1/5	1/9
Maximum travel speed	3400	2000	1100

• Note 1)

  Please note that when the stroke is short, it may not reach the maximum travel speed.

• Note 2)

  The maximum travel speed for actuators with a stainless steel cover is 2500 mm/s.

• Note)

  The timing pulley has a large pitch circle diameter, so THK recommends the use of a reducer.

Built-in Caged Ball LM Guide model SHS.
Long service life and long term maintenance-free operation are possible because there is no mutual friction between the balls and grease retention is improved due to the effect of the caged ball.

QZ Lubricator is equipped as standard*.
The QZ Lubricator supplies an optimal amount of lubricant to the raceway of the LM rail, substantially extending maintenance intervals.

* For Model TY, the QZ Lubricator is equipped on a single side only for each LM block.

A tightly sealing stainless steel cover prevents foreign matter from entering the actuator.

* Please note that, with a stainless steel cover, maximum base length and maximum travel speed will be restricted. (Maximum base length: 3540 mm; maximum travel speed: 2500 mm/s)
