Carr Lane SP-32-8-.1562 | 1/2" OD x 1/2" Length Serrated Press-Fit Bushing

Serrated Press-Fit Bushings (SP)

Bushings are similar to P bushings, but with top serrations to prevent rotation in soft materials. SP bushings are recommended in high-torque situations for materials such as magnesium, aluminum, masonite, or wood. Serrations also resist axial force to prevent pushing the bushing through the jig plate.

Application Information

SP bushings have top serrations to prevent rotation in softer materials, such as magnesium, aluminum, masonite, or wood. Finish-ground OD ensures accurate ID location.

ID Tolerance

Standard ID Tolerance:

From #80 to 1/4" +0.0001/+0.0004

Over 1/4 to 3/4" +0.0001/+0.0005

Over 3/4 to 1-1/2" +0.0002/+0.0006

Over 1-1/2 to 2-3/4" +0.0003/+0.0007

Reamer ID Tolerance (Special):

From #80 to 1/4" +0.0005/+0.0008

Over 1/4 to 3/4" +0.0006/+0.0010

Over 3/4 to 1-1/2" +0.0008/+0.0012

OD Tolerance

Standard OD Tolerance:

13/64 to 1"       0/-0.0002

No-Counterbore Option on Long Bushings

Extremely long bushings with a small ID size are counterbored according to ANSI standards for proper drill-bearing length to eliminate binding and heat buildup. Add "-NCB" for applications that require these bushings without a counterbore.
