Decoding the designation

3 — the SealMaster 3-series medium-duty insert, built to drop into SealMaster machined housings.

13 — the size within that series, giving the 1-3/16 in shaft and the 2.8350 in outside diameter.

D — the execution supplied on this insert.

What these specs mean in practice

Bore / Shaft Size: 1-3/16 in. Outside Diameter: 2.8350 in. Overall Width: 1.6880 in. Outer ring width: 0.9380 in. Internal Clearance: Standard.

The overall width runs well past the outer ring width, so the inner ring extends on both sides of the balls. That extension is what carries the setscrew locking collar and gives it a long grip on the shaft, which steadies the insert against tipping under a belt pull. Locking Method: Setscrew locking collar — the collar sits against the extended inner ring and its screws bite into the shaft, which is the quickest form to fit and to strip and holds well where rotation runs consistently in one direction. Standard internal clearance suits general plant service at ambient shaft and housing temperatures.

Housing style and mounting form

The insert seats in a SealMaster machined housing at this outside diameter, across the pillow block, flange and take-up ranges, and is replaced independently of the housing it runs in.

Mounting data

Interchange guidance

MPN Variants: 3-13D, 313D, 3-13 D, 3-13. SealMaster runs the same 3-series medium-duty insert at other sizes, so the 3-1 is the 1 in shaft member of the same family. The SealMaster ER-13 is a separate insert series carrying the same 13 size code.
