Bell Type Mounts FRS

FRS bell-type series shock absorbers can achieve very high shock absorption effects in both axial and lateral pressures, especially when used in engines and engine systems, the shock absorption effect is very obvious. The rubber and iron parts inside the product are completely adhered, and in addition, there is a safety lock in the middle to lock the product, which is very reliable and durable. In addition, there are grooves on the metal cover to help remove oil and other pollutants and prevent contact with the rubber part.

FAQ

1. I see this is an FRS series. What does "FRS" stand for or indicate in terms of its special use?

Great question on the naming. While specific letter codes can vary, our FRS series is generally engineered for applications demanding a focus on durability under frequent stress cycles and stable performance in variable conditions. Think of it as a robust variant optimized for equipment that runs continuously with consistent vibrations or undergoes regular operational cycles. It's an excellent choice for the long-term isolation of industrial fans, blowers, compressors, and medium-duty machinery where reliable, maintenance-free performance is the priority.
2. Our main challenge is space. We need to retrofit isolation under existing machines in a crowded plant. Is the FRS mount compact enough, and is installation feasible without major disassembly?

Space constraints are common, and the FRS series is designed with retrofit-friendly installations in mind. Its bell shape provides high performance in a relatively compact footprint. The key is our "jack-and-place" installation method. Using standard hydraulic jacks or lifting equipment, your maintenance team can safely lift a machine corner just enough to slide the FRS mount into position. This makes it ideal for upgrading vibration control on existing production line equipment with minimal downtime and no need for full machine dismantling.
3. We have many machines of similar type but different weights. Is there a simple rule or chart to standardize on one or two FRS models across our factory floor?

Yes, simplifying inventory is a smart strategy. We provide a simplified FRS selection guide based on machine categories and weight ranges. For instance, all your mid-size centrifugal pumps within a certain weight band can typically use the same FRS model. By providing a list of your equipment types and their approximate weights per support point, we can help you consolidate and standardize vibration isolator part numbers, reducing complexity in your maintenance and procurement processes.
