Bell Type Mounts DBL

The DBL series is extremely versatile and can be used to solve various compression force applications (such as generators, pumps, compressors, etc.). Compared to traditional complex shock absorbers, they are a simpler and more e****mical choice. These mounting parts can be configured with threads (VBL) or assembled with nuts (DBL), and are designed with a flange base to simplify the installation of the final product. This range of shock absorbers can accommodate loads of about 30 kilograms to about 2500 kilograms/mounting.

FAQ

1.Your description says DBL is a "more economical choice." Does saving money mean I'm compromising on performance or durability for my pumps and generators?

This is a vital distinction. "Economical" here refers to value-engineered simplicity and cost-effective installation, not reduced performance. The DBL delivers robust vibration isolation for common industrial equipment by using an efficient, proven bell-type design without unnecessary complex features. You get reliable performance for dampening vibrations from rotary equipment without the higher cost of over-specified or overly complex systems. It’s about smart spending—getting the right level of isolation for applications like standard pump bases or generator set mounting without paying for capabilities you don't need.
2. I'm not an engineer. With a load range from 30kg to 2500kg, how do I simply figure out which exact DBL model I need for my specific machine?

You don't need to be an engineer. The key is the total weight of your equipment and the number of mounting points. For example, if your air compressor weighs 1000kg and sits on four feet, each mount needs to support about 250kg. We provide a clear load capacity chart for the DBL series. You match your calculated load per mount to the chart to find the correct model. For standard machines like industrial fans or mid-sized compressors, this process is straightforward. We can also assist with this basic load calculation for machinery isolation if you provide your equipment's details.
3. What's the real difference between the "threaded (VBL)" and "with nuts (DBL)" configuration? Which one is easier for my maintenance team to install?

The choice impacts installation method and flexibility:
DBL (with nuts): This configuration is typically the simplest for bolt-through applications. You place the mount, pass a bolt down through the machine foot and the mount's center hole, and secure it with a nut underneath the flange. It's very straightforward.
VBL (threaded): Here, the mount has a threaded insert. You screw a bolt directly down into the mount from the machine foot. This can be slightly neater. For most on-site retrofit projects, the DBL (with nuts) style is often preferred for its ease of alignment and installation flexibility. The integral flange base on both types prevents sinking and simplifies positioning.
4. My equipment is in a rough industrial environment with oil mist and dirt. Is the rubber in the DBL suitable, or will it degrade quickly?

The DBL series uses a general-purpose industrial elastomer that provides good resistance to common conditions like moderate oil splashes, dust, and ambient moisture typically found in workshops and plant floors. For severely contaminated or chemically aggressive environments, we would recommend a different series with specialized compounds. For the vast majority of enclosed compressor installations or pump rooms, the DBL's material offers a great balance of environmental resistance and cost-effectiveness for standard factory conditions.
