Bell Type Mounts FRSQ

FRSQ bell-shaped 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. What is the "safety lock in the middle," and why is it a big deal for reliability?

The internal safety lock is a critical durability feature. In some mounts, under extreme shock or over years of fatigue, the rubber can potentially separate from the metal core—a catastrophic failure. The FRSQ's internal mechanical safety lock physically bonds and locks the rubber to the metal skeleton at the core. This isn't just adhesive; it's a positive mechanical interlock that prevents core separation in heavy-duty shock absorbers, ensuring the unit fails safe and maintains integrity. This is why we highlight its use in high-reliability engine mounting systems.
2. My engine room is hot and oily. The note about "grooves to remove oil" sounds good, but does the rubber itself also resist breaking down from constant oil exposure?

You've identified the two-part defense strategy of the FRSQ. First, the protective grooves on the metal cover act as a channel to divert spilled oil and fluids away from the main rubber body, reducing constant contact. Second, and crucially, the rubber compound itself is formulated to be highly resistant to degradation from engine oils, fuels, and high ambient heat. This dual approach—physical contaminant drainage and oil-resistant elastomer formulation—provides extended service life in the harsh environment of marine engine compartments or industrial generator enclosures.
3. How does the "rubber and iron parts completely adhered" process make a difference in everyday performance versus a cheaper mount?

This refers to a high-quality vulcanization bonding process. In cheaper mounts, the rubber might be simply pressed onto the metal, leading to de-lamination under stress. The FRSQ's complete vulcanized adhesion creates a single, unified component. This eliminates internal micro-movements that cause heat buildup and premature failure. In practice, this means more consistent damping performance over a wider temperature range and longer service life under continuous vibration, which is why it's specified for durable mounting in drivetrain and power generation equipment.
