The super 8 is an adjustable, self aligning bearing. Check out the spb 8 adj on the danahermotion web site. By duplicating the slot to adjust the tolerance of the hole you can increase the preload. With extreme caution you can make the hole slightly undersized or the shaft slightly oversized (by about .0001~.0002") and you can achieve a preload. You want to use good aluminum (t6) or the bearing plates will Brinell the housing and you will develop play over time. |
