Custom PA66 Industrial Cable Reel Hub
A cable reel hub forms the interface between a spool assembly and its supporting shaft. A loose bore can allow movement during winding, while an unsuitable flange can interfere with the reel side plate. SWKS supplies custom injection molded PA66 hubs for industrial cable handling equipment, with the bore, flange and attachment features developed around the customer assembly drawing.
Geometry Built Around the Reel Assembly
The illustrated configuration combines a hollow barrel with a circular mounting flange and radial ribs. The bore locates the hub on the shaft, the flange provides an attachment surface, and the ribs support the transition between these sections. This is an illustrative custom configuration; dimensions and final geometry are subject to drawing review and sample approval.
Depending on your installation, the design can incorporate a stepped bore, a locating shoulder, clearance holes, a keyed interface or insert mounting features. Features that transmit torque must be checked against winding tension, start-stop duty and the shaft connection. A round bore alone should not be assumed to provide a positive drive.
PA66 Grade Selection
PA66 offers a useful balance of stiffness, toughness and wear behavior for many industrial components. The appropriate grade depends on load, temperature, humidity and contact conditions. Unfilled and glass reinforced grades have different behavior, so reinforcement content is selected during technical review rather than treated as a standard specification.
Nylon absorbs moisture, which can affect dimensions and mechanical properties. For a shaft fit, specify the operating environment and conditioning state used for inspection. Critical bore measurements and assembly clearances are reviewed against these requirements. Flame rating, electrical properties, UV resistance and chemical compatibility require confirmation for the selected resin grade.
Details to Confirm Before Tooling
- Shaft diameter, bore tolerance, fit type and allowable runout.
- Flange diameter, thickness, hole positions and mating surface.
- Torque path, winding tension, rotational speed and operating cycle.
- Operating temperature, humidity and exposure to oils or cleaning fluids.
- Resin grade, reinforcement, color and permitted material sources.
- Inspection conditions, sample approval criteria and order quantity.
Injection Molding Review
Rib thickness, transitions and gate position need to suit the selected PA66 grade. Excessively thick sections can create sink marks or uneven shrinkage, while sharp rib roots concentrate stress. Tooling review considers draft, ejection and accessible inspection datums so that the hub can be molded and checked consistently. Where close fits are required, discuss whether the bore should be molded to size or finished in a secondary operation.
Applications and Related Components
Potential applications include cable take-up and pay-off equipment, industrial spool assemblies, reel support systems and custom winding machinery. Suitability depends on the approved assembly design and operating conditions. Explore our custom molded nylon parts and plastic injection parts for related industrial assemblies.
Quotation and Sample Approval
Send a STEP, STP or IGS model together with a dimensioned drawing identifying critical fits. Please also provide expected order volume, material requirements and intended equipment. Tooling scope, sample schedule, inspection requirements and production lead time are confirmed after review. Production follows the agreed drawing and approved samples.
