FAQs
To install QM/8125/21, attach the cylinder to the designated foot-mounting points on your frame using the supplied fasteners, align the bore with the drive element, and ensure proper end-positions are preset. Verify return springs or cushions are configured per your stroke requirements, and confirm that clearances around the 125 mm bore support smooth travel through the 45 mm height and 140 mm length profile. This approach minimizes misalignment and optimizes cycle consistency across the line.
The QM/8125/21 features a 125 mm cylinder diameter, 45 mm height, 140 mm length, and 65 mm width, with a weight of 2.4 kg. These dimensions define its compact footprint for tight automation bays while maintaining substantial force capacity. When selecting mounting accessories, ensure compatible end fittings and actuator guides match the 125 mm bore and overall package size.
Yes. Norgren provides CAD resources and a datasheet for QM/8125/21 to streamline design-in and integration. Access CAD files to verify mounting envelopes, stroke limits, and interface dimensions, then cross-check against your machine frame and linkage. The datasheet offers full dimensional data and installation notes, helping engineers assess fit and performance before procurement.
For this class of actuator, CE safety compliance is typically pursued to meet European safety standards, and IP-rated protection is commonly specified for devices exposed to dust, moisture, or washdown environments. While the data here does not list explicit certifications, engineers should verify CE markings and IP rating in the specific product variant and with the supplier before deployment in critical safety or washdown zones.
QM/8125/21 offers predictable actuation with a robust 125 mm bore and durable German engineering, contributing to higher uptime and lower rework due to mis-stroke or misalignment. The availability of CAD resources and datasheets reduces engineering time, while standardization of mounting and dimensions minimizes spare parts variety, leading to lower total cost of ownership over the actuator’s lifecycle.
