Product information "Guide bushing, conical | SM 1273-55"

with collar
with conical bore
for indexing plungers SM 1273-51

Material:
ST: special steel
hardened (HRC 62 ±2) and ground
NI: stainless steel
hardened and ground

The positioning bushings SM 1273-54 and SM 1273-55 with conical bore are used for
the detent bore of indexing plungers SM 1273-51 and allow precise positioning.
The length l7 of the indexing pin is determined by the depth of penetration of the indexing
pin into the cone of the bushing.
The length l8 must ensure complete disengagement of the indexing pin.
When engaged, the pin must have at least 0.5 mm residual stroke so that the conical part of the pin is seated in the cone of the positioning bush without play.
To accommodate the positioning bushings (outer Ø with tolerance n6), the locating holes hould have tolerance H7.

RoHS-compliant: yes

Compliance: RoHS compliant
Material: Stainless steel, Steel
Speciality: Bore - conical

Larger guide lengths further increase the precision.Two different plunger pin lengths l1 are available for each indexing plunger diameter d1.The length l7 is determined by the penetration depth of the plunger pin into the cone of the bushing. The length l8 must ensure that the plunger pin fully disengages, bushing length and plate thickness plus any gap can then be selected within certain margins.If engaged, the pin must have a minimum remaining stroke of 0,5 mm to make sure that the conical section of the pin is located without clearance in the cone of the guide bushing. For a safe remaining stroke length: l9 = l1 - 0,5 mm.To accommodate the positioning bushings (outer Ø with tolerance n6), a locating holewith tolerance H7 is usually provided. Type C is used for such applications where the plunger has to stay in its retracted position.To achieve this, the knob is rotated by 90° degrees after being retracted.A notch keeps the plunger in this position. RoHS-compliant: yes
