Drafting quality lives or dies on roller condition. The LM-SP40 set delivers bottom fluted rollers and matched top roller cots ground to original drawings: flute geometry, hardness and concentricity inspected piece by piece, with the measurement record in the box.
Rollers ship in matched sets for a complete drafting zone, so replacement restores the geometry the frame was commissioned with rather than mixing wear states. Journals arrive protected and greased, ready to seat in existing bearings.
The set fits Loomstead frames as standard; adapter specifications for common third-party frames are available on request.
