ZJX Adjustable Self-Centering Lens Holders

Three adjustable curved arms grip round optical components across a broad diameter range, making ZJX mounts useful when a fixed-bore holder would not fit. Dedicated images label 50, 80, 120 and 150 mm clear openings and a 5 mm-to-model-maximum clamping range. Family details identify an M4 side mounting hole and a locking knob. “Self-centering” describes the mechanism but is not a stated centering-error or repeatability specification; obtain those numbers for critical optical alignment. English artwork illustrates the family only.

Four grip ranges

The ZJX-50, -80, -120 and -150 images label clear openings of 50, 80, 120 and 150 mm respectively, with corresponding clamping spans of 5–50, 5–80, 5–120 and 5–150 mm. Verify contact geometry, optic thickness and secure grip for the actual part.

Adjustment and lock

Three curved arms adjust around the optic. Exterior adjustment posts and a lock knob are visible; arm synchronization accuracy, maximum grip force and acceptable edge shape are not specified.

Mounting

The family detail labels an M4 side mounting hole and illustrates post-mounted use. Confirm whether any post, base or optic is included; the installation scene does not establish the packing list.

Precision limits

The source gives no grip depth, minimum contact area, load capacity, vibration performance, centering error or repositioning repeatability. Do not infer optical precision from the product name.

Selection checklist

Match optic diameter to clamping range

Check clear aperture and edge-contact position

Check M4 mounting and available clearance

Request centering and load data for critical setups
