Norgren QA/8100/41 Swivel Bearing - 125 mm Diameter
Part Number: QA/8100/41
Quick Summary
Norgren QA/8100/41 is a precision swivel bearing used to support high-load rotary motion in automated machinery. Engineers often struggle with misalignment, wear, and downtime when mounting rigid bearings in compact automation layouts. In practice, CE conformity and IP ratings are common expectations, and SIL considerations may apply to safety-critical lines; verify the datasheet for exact certifications. The design supports efficient installation within automation and control systems, improving uptime. By pairing German engineering with a compact footprint and readily available CAD resources, manufacturers can shorten commissioning time, reduce spare-parts inventory, and improve overall equipment effectiveness (OEE).

FAQs
To ensure reliable performance, begin with clean mounting surfaces and align the bearing with the mating flange pattern. Use appropriate fasteners, verify torque specifications from the CAD drawing, and confirm the assembly allows free rotation without binding. Lubrication should follow the manufacturer’s guidance, and protective shields should be installed to minimize contamination in automation environments.
Yes. The QA/8100/41 is designed for compatibility with common Norgren components and standard pattern mounts used in automation and control systems. Access CAD models and datasheets to verify hole spacing, mounting clearance, and enclosure compatibility before procurement, which reduces rework and accelerates installation.
Key specs include a cylinder diameter of 125 mm, dimensions of 50 mm height, 75 mm length, and 28.5 mm width, with a weight of 0.34 kg. Country of origin is Germany, reflecting the engineering quality.
