(Note 1) An adapter plate is available for lubricating the actuator guide from the grease nipple with the bellows still attached. For details, contact THK.

(Note 2) The degree of shrinkage differs when the bellows are used in applications outside of horizontal use (e.g. vertical or wall-mounting use). For details, contact THK.


		A (degree of shrinkage)
	KR33	7
	KR46	7

(Note) Calculate the length of the bellows by the following equation:

S: Stroke length (mm)

Lmin =

(A-1)

Lmax = Lmin • A A: Degree of shrinkage (see table at right)
