Overview: Newport Model 270 Lab Jack
The Newport Model 270 is a high-load, manual vertical lab jack designed for precise and stable vertical positioning of optical or mechanical equipment.
Key Features & Design:
-
Innovative Hinge Mechanism
Utilizes three orthogonal hinge pivots that form a box-like structure when raised, enhancing its stability and resistance to wobble, tilt, or twist—especially at greater heights. -
Vertical Motion & Stability
A side-mounted drive screw actuates height adjustment by controlling the pivot pins of the side-hinges, while an end hinge prevents any deviation from vertical motion.
Dimensions & Mounting:
-
Top platform measures ~4.375″ × 6.5″ (about 111 × 165 mm).
-
Equipped with an array of 1/4-20 threaded holes on the top (spaced on 1-inch centers).
-
The base may offer M6 threaded holes for metric compatibility.
Travel Range & Load Capacity:
-
Though exact travel and load specs for Model 270 are not always clearly stated, it’s suggested to be comparable to the newer Model 271, which offers 44.5 mm (1.75″) travel and a load capacity of up to 900 N (~200 lb).
-
Some seller listings describe Model 270 with a 2.3″ (≈58 mm) travel and a platform size of 6.5″ × 4.3″, with 1/4-20 holes.

Tips for Procurement or Use
-
Verify Specifications: If exact travel and load ratings are important for your use, consider reaching out to Newport directly or consulting technical documentation—Model 271 specs can offer insights for comparison.
-
Mounting Options: The presence of both imperial and metric threading makes it adaptable for a wide range of lab setups and optical tables.
-
Consider Model 271: For officially documented performance (44.5 mm travel, 900 N load), Newport’s Model 271 is a closely related and more thoroughly specified alternative.
