Product Number: ESL
The ESL is a 230 mm enclosed spring mounting designed for mid-range load-bearing applications that demand high deflection and low natural frequency isolation. With an overall diameter (A) of 230 mm, a working height (C) of 200 mm, internal geometry dimensions of B 80 mm, D 175 mm and E 150 mm, and an M12 thread (G) with a 12 mm stud diameter (F), this mount occupies the central band of the enclosed spring mounting range, sized above lighter-duty siblings and below the heavy-duty ESL-HD, making it suited to applications where the load requirement sits firmly in the mid bracket. Constructed using rubber-to-metal bonded technology, the ESL can be loaded in shear, compression, or a combination of both, which gives installation engineers flexibility when addressing complex vibration paths. The enclosed housing protects the spring element from the operating environment, and the mount is rated to a maximum working deflection of approximately 20 mm, the standard figure for the enclosed range (the ESL-HD provides 40 mm for extreme applications). Softer rubber grades within this geometry deliver greater deflection and better isolation under lower loads, while harder grades carry higher loads with reduced movement; the ESL's mid-range sizing makes it a practical choice across a broad span of Shore A selections. Typical application sectors for this mount include marine installations, power generation plant, railway and mass transit equipment, and agricultural machinery, environments where structural protection and operator comfort must be maintained alongside reliable vibration attenuation.

A. The ESL has an overall diameter (A) of 230 mm, a spring housing diameter (B) of 80 mm, a working height (C) of 200 mm, an internal dimension D of 175 mm, an internal dimension E of 150 mm, a stud diameter (F) of 12 mm, and an M12 thread (G).
A. The ESL is rated to a maximum working deflection of approximately 20 mm under normal operating conditions. This is the standard figure for the enclosed spring mounting range; the heavy-duty ESL-HD is rated to 40 mm where greater deflection is required.
A. The ESL is suited to marine, power generation, railway and mass transit, construction and off-highway, agriculture, automotive, and military and defence applications — wherever high deflection and low natural frequency isolation are required to protect surrounding structures and improve operator comfort.
A. Yes. The ESL may be loaded in shear, compression, or a combination of both, allowing installation engineers to address vibration from multiple directions within a single mount.
A. Yes. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds can be specified on request, as can additional and custom sizes beyond those held in the standard range.
A. The ESL occupies the mid-range position in the enclosed spring mounting family. Smaller variants include the ESL25/100, ESL25/200, ESL25/1000, ESL25/1200, and ESL25/1400. The ESL-HD is the heavy-duty enclosed variant rated to 40 mm deflection. Open spring mounting alternatives are the ESM and ESS.
A. Softer Shore A rubber grades produce greater deflection and provide better vibration isolation under lower loads, while harder grades carry higher loads with reduced movement. The appropriate grade depends on the static load and isolation frequency required for the specific installation.
A. We accept all major credit and debit cards, along with PayPal.
