Q 1. What are the key dimensions of the ECC2174-45-45 eccentric bush?

A. The ECC2174-45-45 has an inner diameter (A) of 24 mm, outer diameter (B) of 75.3 mm, overall length (C) of 51.0 mm, flange diameter (D) of 70 mm, and a dimension E of 10.5 mm.

Q 2. What stiffness and deflection figures does the ECC2174-45-45 offer?

A. The ECC2174-45-45 has a radial stiffness (F1) of 750 N/mm and an F2 stiffness of 600 N/mm, with a maximum deflection of 3.5 mm and a maximum load rating of 270 kg.

Q 3. Why choose a 45 Shore A grade over a harder grade for this bush?

A. A softer 45 Shore A grade gives greater deflection and better vibration isolation at lower load. It is the appropriate choice for lighter, more sensitive, or compact installations and for lower-frequency isolation requirements where compliance and energy absorption matter more than maximum load resistance.

Q 4. What applications is the ECC2174-45-45 designed for?

A. This bush is suited to pivot bearings, mechanical linkages, cab mounts, and engine mounts across construction and off-highway, agricultural, marine, power generation, railway and mass transit, and automotive applications. It is particularly well matched to lighter duty and sensitive installations where vibration isolation is the primary requirement.

Q 5. Does the ECC2174-45-45 require lubrication or scheduled maintenance?

A. No. The rubber-to-metal bonded construction of the ECC2174-45-45 requires no lubrication and is entirely maintenance free.

Q 6. Can this bush be loaded in different directions?

A. Yes — the ECC2174-45-45 may be loaded in shear, compression, or a combination of both, giving flexibility across a wide range of mounting configurations.

Q 7. Are other sizes or grades of eccentric bush available?

A. Yes. The ECC2174-45-45 is part of a wider range that includes ECC1165-45, ECC1165-60, ECC1270-45, ECC1270-60, ECC1270-75, ECC1355-45, ECC1355-60, and ECC2174-60. Custom sizes, stainless steel metalwork, and oil-resistant or high-temperature rubber compounds are available on request.

Q 8. What is your returns policy?

A. We accept returns within 30 days of purchase for items that are unused, undamaged, and in their original packaging. Returns are available only for UK-delivered orders and must include proof of purchase. Before returning an item, please contact us at [email protected] to obtain a Return Merchandise Number (RMN).

Q 9. When will my order be dispatched?

A. In-stock orders placed before 14:30 Monday to Friday are usually dispatched the same day.
