Weicon WEICONLOCK\u00ae AN 306-30 High-Strength Retaining Compound is an anaerobic industrial adhesive designed to permanently secure parts in cylindrical assemblies. In metal-to-metal fits such as bearings, shafts, bushings, and hubs, it cures where air contact is cut off, fills the gap, and focuses on preventing the joint from loosening. Its high-viscosity structure helps the adhesive stay controlled along the joint line during application. The manufacturer is WEICON GmbH & Co. KG, headquartered in Germany.<\/p>\n
Securing cylindrical assemblies with WEICONLOCK 306-30
\nThis product is positioned specifically for reliable retention of cylindrical fits, particularly on passive metals (e.g., stainless steel). In press-fit assemblies or joints with larger surface areas, the recommended approach is to wet both surfaces thinly and evenly. The bond formed after curing stands out with a \u201cdifficult to remove\u201d character in applications aiming for maintenance-free fixing. In this sense, it can be considered an industrial adhesive alternative that provides an extra safety layer in addition to mechanical locking.<\/p>\n
Anaerobic chemistry and performance framework of 306-30
\nIts green, fluorescent formulation supports application control, while the high-viscosity range helps limit flow. The product can also be used on threaded connections up to M36 and aims to reduce the risk of seepage\/loosening in cylindrical tolerances with a maximum gap-bridging capacity of 0.2 mm. Since the shear strength is specified in the 20\u201330 N\/mm\u00b2 range, it is positioned to create a strong bond for high-strength fixing tasks. Handling strength at room temperature is given as approximately 2\u20135 minutes, and the final strength window is defined as about 2\u20134 hours, which helps plan commissioning after assembly. With a temperature resistance specified from -60 \u00b0C to +200 \u00b0C, it makes industrial adhesive selection more predictable for equipment exposed to temperature changes.<\/p>\n
Surface preparation and application method
\nCleaning and degreasing the surfaces before assembly directly affects bond quality in anaerobic systems. The product should be applied evenly with the dosing nozzle, and it is preferable not to let the tip come into direct contact with metal; this approach helps reduce the risk of unwanted reaction inside the packaging. For press-fit and larger parts, wetting both surfaces as a thin film supports more uniform curing. In slip fits, lightly twisting the parts during assembly can help the adhesive spread better and contribute to more stable retention.<\/p>\n
Applications, compatible systems, and key advantages
\nBearing seats, shafts, bushings, gear hubs, and similar cylindrical fits are among the product\u2019s typical application areas. In machine manufacturing, maintenance\/repair, power transmission systems, and process equipment, it offers a permanent fixing approach where vibration and dynamic loads could loosen the joint. High viscosity increases control on the assembly line, while the high-strength nature aims to achieve a joint that behaves like a single piece. In this way, it supports process reliability as an industrial adhesive solution used in addition to mechanical methods such as pinning or set screws. A minimum shelf life of 24 months at room temperature also provides a practical advantage for consumables planning.<\/p>\n","protected":false},"excerpt":{"rendered":"
