Product category: Specialized products / Accumulator bladder and diaphragm / Bladder accumulator diaphragm for bonded structure
Internal SKU: SCH-1023
SCHWERLL publishes this product as a bladder for adhesive-structured bladder-type accumulators. It is an elastomeric bladder component used within the accumulator assembly; the available product evidence does not establish universal replacement interchangeability or a complete accumulator supply configuration.
The official product description references simulation-based bladder geometry and compression/expansion design, virgin-rubber material, dedicated adhesive bonding / integral molding and production on a specialized manufacturing line.
The manufacturer also describes qualitative low-permeability, stable deformation/oil-drain behavior and long-term durability. These statements are qualitative; the available evidence does not publish numeric permeability, cycle-life or service-life values. The source also describes multiple rubber materials qualitatively, without a component-specific compound and medium compatibility matrix.
SCHWERLL’s official product page references NF ISO 37 / ISO 37 material testing for the bladder. The available evidence does not identify the specific compound, specimen, batch, laboratory or measured result. Elastomer compound, media compatibility, temperature range, dimensions and host-accumulator fitment must therefore be confirmed for the supplied component.

No standalone Post56 bladder pressure rating is established by the available evidence. The published 350 bar and 400 bar values belong to complete BAK/BAKH and BAKM accumulator families. Host accumulator pressure is an important fitment input, but it must not be represented as an independent pressure-vessel rating of the bladder component.
The official SCHWERLL product page references NF ISO 37 / ISO 37 in the bladder material testing context. ISO 37 is a rubber tensile stress-strain test method, not a product certification. The available source does not provide the exact compound, batch, laboratory or test results, so required test documentation should be confirmed for the supplied component.
Confirm the host accumulator manufacturer and model, nominal shell size, bladder geometry and interfaces, hydraulic fluid, precharge gas, operating temperature, host accumulator pressure and required elastomer compound. Exact SCH-1023 manufacturer part-number mapping and interchangeability have not been established by the available evidence.
Please provide the following customer inputs for fitment and material review. These inputs do not establish universal fitment, supplied options or component ratings.
