The John Crane Type 1 series elastomer bellows mechanical seal—including the 1A variant—is renowned as an "industrial workhorse." It features a full‑convolution elastomer bellows that provides automatic adjustment for shaft eccentricity, axial movement, and primary ring wear. A single‑coil, non‑clogging spring architecture drives reliable performance in dirty or low-lubricity fluids, ensuring minimal drive torque and reduced stress on the bellows
The 1A is essentially a variant of the Type 1, designed for high-speed, general-duty pump applications. It falls under the same performance family, offering balanced sealing via the bellows—without the external spring typical in Type 1B.
