Weicon WEICONLOCK AN 301-38 Anaerobic Retaining Compound is a high-strength industrial adhesive developed to secure cylindrical metal assemblies and provide sealing between mating parts. This anaerobically curing product hardens when air contact is cut off and it remains between metal surfaces; in this way, it fills gaps and ensures connection security in interference-fit parts such as bearings, shafts, and bushings. Its medium-viscosity structure supports controlled application while focusing on creating a permanent bond that is difficult to disassemble. Supplied in Germany by WEICON GmbH & Co. KG, the product also stands out with NSF approval information for drinking water applications.<\/p>\n
WEICONLOCK AN 301-38 product description and technical structure
AN 301-38 is classified as a methacrylate resin-based, single-component, anaerobically curing industrial adhesive. It is specifically designed for retaining cylindrical assembly elements such as bearings, shafts, and bushings. The product is green in color and has a medium-viscosity character; this structure provides both controlled flow and balanced gap-filling performance between surfaces. Technical data indicate a viscosity of 2,000\u20133,000 mPa\u00b7s at 25 \u00b0C, a maximum gap-filling capacity of 0.20 mm, and suitability for use on assemblies up to M36.<\/p>\n
AN 301-38 performance features and durability structure
This anaerobic retaining compound is developed to create high-strength, difficult-to-remove connections. Technical data specify a breakaway torque of 30\u201340 Nm, a prevailing torque of 45\u201360 Nm, and a shear strength of 20\u201325 N\/mm\u00b2 according to DIN 54452. It is stated to achieve initial handling strength in approximately 5 minutes at room temperature and reach final strength within 2\u20134 hours. Its temperature resistance is defined as -60 \u00b0C to +150 \u00b0C; for this reason, the product offers a functional industrial adhesive solution in industrial assemblies exposed to mechanical stress and temperature variations.<\/p>\n
Application method and compatible systems
The product is applied evenly to the surface directly from the bottle or dosing tip and cures in areas where it is in contact with metal and isolated from air. Although the best results are achieved on cleaned and degreased surfaces, the manufacturer states that application is also possible on lightly oily surfaces. In press-fit or larger cylindrical assemblies, it is recommended to apply a thin and even layer to both surfaces; in slip fits, rotating the parts against each other during assembly improves distribution. In this respect, the product stands out as a technical industrial adhesive used in close-tolerance metal systems such as bearing-shaft, bushing-housing, sleeves, liners, and similar assemblies.<\/p>\n
Application areas, advantages, and standard information
AN 301-38 can be used in machinery manufacturing, maintenance and repair, pump and gearbox assembly, bearing seating systems, automotive supply industry, general industrial equipment production, and metal part securing processes. It offers particular advantages in cylindrical connections where vibration, loosening, and micro-leakage risks need to be reduced. Its gap-filling capability, high strength, and cured structure with chemical and solvent resistance make it suitable for long-lasting assembly requirements. The product is stated to have NSF approval information for drinking water applications; however, since its safety classification includes warnings for skin and eye irritation\/damage and respiratory tract irritation, SDS instructions must be followed during use.<\/p>\n","protected":false},"excerpt":{"rendered":"
