Frequently asked questions
What is Belzona 7111 used for?
Belzona 7111 is a high-performance epoxy chocking system used to support, align and secure marine and industrial machinery. It creates solid, even support beneath equipment, helps distribute operating loads, fills irregular gaps and can reduce movement and vibration. Typical applications include engines, gearboxes, pumps, compressors, motors, bearings and other heavy machinery.
Can Belzona 7111 replace machined steel chocks?
Yes. Belzona 7111 can eliminate the need for precision-machined steel chocks in many machinery installations. The pourable epoxy conforms to irregular surfaces and fills gaps beneath equipment, creating a close-fitting support that helps maintain machinery alignment and distribute loads evenly.
What marine equipment can be chocked with Belzona 7111?
Belzona 7111 can be used for chocking a wide range of marine propulsion and auxiliary equipment. Applications include main propulsion engines, marine gearboxes and reduction gears, stern tube bearings, strut and cutlass bearings, steering gear, rudder carriers, generators, pumps and other onboard machinery.
What industrial machinery can be chocked with Belzona 7111?
Belzona 7111 is suitable for precision chocking of pumps, pump skids, compressors, electric motors, gearboxes, drive systems, turbines, generators and heavy machinery baseplates. The system provides stable equipment support while helping maintain alignment and reduce movement caused by operating loads and vibration.
How strong is Belzona 7111 and what chocking thickness can it be applied at?
Belzona 7111 has a published compressive strength of 213.1 MPa (30,908 psi) under the specified cure conditions and a recommended application thickness of 12–100 mm (0.5–4 in). It has a working life of approximately 30 minutes at 25°C and a published shelf life of five years. Always refer to the latest Belzona Product Specification Sheet and Instructions for Use when designing an application.
