Specifications:
The document provides specifications for BCA isolators with bottom plates, manufactured by CEF Polymers. The isolators are designed for load management and vibration isolation, with various models available based on load capacity and deflection.

Load and Deflection:
The table lists different BCA models with their respective minimum and maximum load capacities (ranging from 2 kg to 1250 kg) and maximum deflection (ranging from 2.5 mm to 7.5 mm).

Dimensions:
The dimensions for each model type (BCA 40, 60, 80, 100, 150, 200) are provided, including parameters such as diameter, height, and bolt size.

Materials and Construction:
The isolators are made from rubber NR rings bonded to top and bottom fixing plates, with an additional cover plate for rubber protection and mass distribution. They feature anti-slip properties and are available in hardness levels of 45, 60, and 75 Shore A, with a tolerance of +/- 5 Shore A.

Performance Characteristics:
The isolators offer natural frequencies between 16 and 8.5 Hz, are fail-safe, and provide shock damping. They are resistant to oil, grease, and ozone, and are suitable for construction-borne noise isolation and off-road vehicle applications.

Additional Information:
Load/deflection curves are available upon request, providing further insights into the performance under different conditions.
