PIVOT BEARING & PIVOT BEARING BRACKETS

MODELS PT AND PBB
The model PBB Pivot Bearing Bracket and Model PT Pivot Bearing have been designed for use with other Dane components. The pivot bearing bracket is designed to accept the outer race of the pivot bearings and provide a convenient and secure means for clamping a pivot bearing up to 10.63 inches from its mounting surface. The pivot bearing provides a stable, accurate pivot and features ball bearings with double rows of balls. PT1 through PT6 are lubricated and sealed for life; PT0 is lubricated and shielded. A wide range of bearing shaft and side dimensions plus keyway specifications are available for unmatched versatility. CAD files are available.

2. Length, "A" dimension
3. Length, "C" dimension
4. Keyway Angle 
(as applicable)
A 'right hand rule' is used for the angle. With fingers wrapped around either shaft and with the thumb pointing away from bearing housing, the fingers point in the direction of positive angle used for order number.
