Lot of 2 adjustable pressure‑roller carriage assemblies as pictured. Each carriage rides on four V‑groove guide wheels and carries a segmented urethane roller. One unit includes a fine height adjustment via a knurled dial/lead‑screw (0–9 index marked “LOWER”) to set roller pressure against the web or part. Machined aluminum and steel construction with black anodized blocks; segmented urethane roller provides compliant grip and tracking. Likely intended for packaging, conveyor, labeling, or other automation where a hold‑down/drive roller is needed. Likely used in Bell & Howell MailStar series of letter inserters.

Condition note: From a closing industrial facility. Untested but presumed to be working well.

Approximate specifications (per carriage):

- Overall length: ~6.75 in; width (roller OD): ~2.75 in; height to top of wheel block: ~2.5 in (height adjuster unit extends higher)

- Urethane roller OD: ~2.5 in; width: ~2.75 in; segmented rings

- Four V‑groove guide wheels on spring posts; three tapped holes on the top of the block for mounting

- Materials: aluminum frame, steel wheels/hardware, urethane roller segments

Includes: two carriages total; one with dial height adjuster and one without, exactly as shown in pictures.

Applications: web/film hold‑down, conveyor or packaging machine guide/drive, material handling fixture, custom automation.
