Decoding the designation

KG — linear ball bearing supplied already mounted in its housing, as a ready-to-bolt unit.

X — the self-aligning inch-series linear ball bearing insert, closed type.

16 — inch-series size 16, a 1.000 in shaft diameter.

PP — a lip seal at each end of the bearing.

What these specs mean in practice

The housing unit removes the bore-machining job from the design: the flange bolts to a flat face and the shaft alignment is carried by the bearing rather than by the accuracy of a housing bore.

The X-series insert is self-aligning. Each ball circuit sits in a segment that swivels inside the outer sleeve, so shaft deflection and small mounting misalignments are taken up without edge-loading the ball tracks.

Lip seals at both ends keep swarf and grit out of the ball circuits, which is what determines service life on an open round shaft in a machining or handling environment.

Dynamic Load Capacity 810 lbf applies to the ball bushing insert and is the figure the travel-life calculation runs on.

Mounting data

Four-bolt square flange, bolted through the housing face. Shaft seat diameter: 1.000 in (25.4 mm), running on hardened and ground round shafting.

Quantity and configuration

Unit Quantity: 1 Pc. One complete housing unit with its bearing insert and both end seals fitted.

Interchange guidance

KX16-PP is the bare bearing insert used in this unit, on the same 1.000 in shaft with the same 810 lbf capacity. KGXO16-PP is the open-shaft-support version of the same unit for supported rail. KXO16-PP is the open insert.
