Decoding the designation:

NSTU — narrow-slot take-up housing, sized to slide in the narrow rail section of a Dodge take-up frame.

DL — D-LOK concentric clamp collar, which grips the shaft evenly all the way round instead of biting at two setscrew points.

207 — bore code for a 2-7/16 in shaft.

What these specs mean in practice:

Locking Method: D-LOK concentric clamp collar. A concentric grip centres the insert on the shaft, so the assembly runs with less vibration at speed than a setscrew unit and resists creep under reversing or shock load. Dynamic Load Rating: 11,791 lbf and Static Load Rating: 8,100 lbf set the load ceiling for a 212-series ball insert. Closure Type: Single-lip seal, which keeps grease in and coarse debris out on general conveyor duty.

Housing style and bolt pattern:

Housing Style: Narrow-slot take-up. The housing has machined guide faces that run in the slot of the take-up frame, and a threaded boss that takes the frame’s adjusting screw. Overall Length: 6.69 in. Overall Height: 5-3/4 in.

Fitting notes:

Expansion Type: Non-expansion — the insert holds the shaft in axial position, so a floating unit belongs at the opposite end of the shaft. The unit slides into a Dodge NS415 narrow-slot take-up frame, and the frame’s screw draws it along the rail to tension a belt or chain.

Quantity and configuration:

Unit Quantity: 1 Pc. Take-up cartridge complete with its ball bearing insert and D-LOK collar. The matching frame is the Dodge NS415.

Interchange guidance:

Part Number: NSTU-DL-207. Base Number: 064430. Searchable variants: NSTUDL207, NSTU DL 207, NSTU-DL207. The setscrew equivalent on the same housing is the Dodge NSTU-SC-207, item 125162 — same envelope, setscrew locking rather than a concentric collar.
