Description

TN twin-rod pneumatic cylinders

TN cylinders use two parallel rods connected to a common moving plate. Select bore and stroke for the required travel, then match the port and mounting layout. The ordering example TN25x20 denotes a 25mm bore and 20mm stroke.

Ordering field	Example	Meaning
Series	TN	Double-acting twin-rod cylinder
Bore × stroke	25×20	25mm bore × 20mm stroke

TN cylinder body, extended twin rods and mounting faces — TN construction views show the moving plate, twin rods and body mounting holes.

Stroke and position switch selection

Compare listed standard strokes with the separate allowable and maximum stroke limits. The allowable-stroke figure is a travel limit, not a dimensional tolerance.

Bore (mm)	Standard strokes (mm)	Allowable stroke (mm)	Maximum stroke (mm)	Switch option
10	10, 20, 30, 40, 50, 60, 70	70	100	CS1-G
16	10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 125, 150	150	200
20	10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 125, 150	150	200
25	10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 125, 150	150	200
32	10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 125, 150	150	200

10mm bore outline

Dimensions are in millimeters. Use A, B, C and D with the stroke additions shown on the drawing; E changes with the stroke threshold.

TN10 twin-rod cylinder outline and M5 port dimensions — 10mm bore outline with mounting-hole references and two M5×0.8 ports.

Bore	A	B	C	D
10	58	12	46	10

Stroke ≤ (mm)	10	20	30	40	50	60	70
E (mm)	30	30	35	40	45	50	55

32mm bore outline

TN32 twin-rod cylinder outline and PT1/8 port dimensions — 32mm bore outline with mounting-hole references and two PT1/8 ports.

Bore	A	B	C	D
32	108	30	78	35

Stroke ≤ (mm)	10	20	30	40	50	60	70	80	90	100	125	150	175
E (mm)	45	50	55	60	65	70	75	80	85	95	102.5	115	122.5

The 175mm dimensional entry describes an extended-stroke configuration and does not change the 150mm allowable-stroke figure in the selection table.
