Variations
Rated to a maximum load of 23.0 kg with a controlled deflection of 5.0 mm, this 15 x 20 mm Female Flat Buffer with M4 thread (1520FFB04-60) occupies the balanced mid-point of the range, calibrated at 60 Shore A to deliver an even trade-off between vibration isolation and load-bearing support across a broad spread of compact machinery applications. Rubber-to-metal bonded construction gives the buffer its characteristic blend of resilience and structural integrity. At 60 Shore A, the medium hardness grade neither prioritises maximum deflection nor maximum stiffness; instead it offers a general-purpose performance envelope well suited to equipment where moderate vibration attenuation and dependable positional support are both required. The female thread configuration allows direct fastening to a stud or threaded component, simplifying fitment where a retained, in-line mounting point is needed. Custom stainless steel metal inserts and oil-resistant or high-temperature rubber compounds are available on request. With a 15 mm diameter and 20 mm height, this is the smallest geometry within the Female Flat Buffer range, making it particularly appropriate for lighter installations where space is constrained: industrial machinery panels, agricultural equipment housings, commercial vehicle cab components, and power generation auxiliaries all represent typical service environments. The 23.0 kg maximum load and 5.0 mm deflection figure define its operating envelope clearly, adequate for real compressive and shear duties on compact assemblies without over-specifying.

A. This Female Flat Buffer measures 15 mm diameter by 20 mm height (D x H: 15 x 20), takes an M4 thread, has a maximum load rating of 23.0 kg, and a deflection of 5.0 mm.
A. The 60 Shore A medium grade sits between the two extremes: it provides a balanced combination of vibration isolation and load-bearing support, making it the general-purpose choice where neither maximum compliance nor maximum stiffness is the priority. The 45 Shore A grade (1520FFB04-45) offers greater deflection and better isolation at lower loads, while the 70 Shore A grade (1520FFB04-70) carries higher loads with less movement.
A. The source data cites construction equipment, industrial machinery, agricultural equipment, commercial vehicles, and power generation equipment as typical applications. Industries served include construction and off-highway, agriculture, marine, railway and mass transit, automotive, and military and defence.
A. The buffer works by absorbing and dissipating energy from impact shocks and vibration transferred by external moving components or contact surfaces. Rubber-to-metal bonded construction means the rubber element is permanently bonded to its metal insert, giving a secure, integrated assembly that resists separation under load in shear, compression, or combined loading.
A. Yes — at 15 x 20 mm with an M4 thread, this is the smallest geometry in the range featured here. Larger variants with M16 threads are available in sizes including 100 x 100 mm (100100FFB16), 100 x 30 mm (10030FFB16), 100 x 40 mm (10040FFB16), 100 x 50 mm (10050FFB16), 100 x 55 mm (10055FFB16), and 100 x 60 mm (10060FFB16).
A. Yes — stainless steel metal inserts and oil-resistant or high-temperature rubber compounds are available on request, as are additional and custom sizes.
