Product Number: 5030FFB12-45
Variations
Engineered for maximum vibration isolation, the 5030FFB12-45 Female Flat Buffer measures 50 mm diameter by 30 mm height with an M12 female thread and a soft 45 Shore A rubber compound, a combination that delivers the greatest deflection and most effective isolation of lower-frequency vibration within this flat-buffer geometry. At this hardness grade, the mount is rated to a maximum load of 252.0 kg with a generous deflection travel of 7.50 mm, meaning the rubber works over a wider movement range to absorb and dissipate energy before it reaches the host structure. This high-movement characteristic makes the 45 Shore A grade particularly suited to sensitive or lighter equipment where isolation quality matters more than stiffness or positional restraint. The rubber-to-metal bonded construction joins vulcanised rubber directly to a threaded metal insert, creating a durable assembly that resists pull-out and misalignment under cyclic loading. The female M12 thread accommodates a wide variety of bolt-down configurations and allows clean flush-mounting against equipment panels or frames. Custom variants in oil-resistant or high-temperature rubber compounds, as well as stainless steel metalwork, are available on request for more demanding process environments. The buffer is suited to applications across construction equipment, industrial machinery, agricultural equipment, commercial vehicles, and elevators, any installation where a soft, compliant mount is preferred to reduce transmitted vibration, cushion impact from external moving components, or protect surrounding structures and improve operator comfort.

A. This buffer is rated to a maximum load of 252.0 kg with a deflection of 7.50 mm, characteristics that reflect the soft 45 Shore A compound's ability to absorb and dissipate energy across a wider movement range than harder grades.
A. Softer grades give greater deflection and better isolation, particularly at lower loads and lower frequencies. The 45 Shore A grade is most appropriate where isolation quality is the priority — lighter or sensitive equipment where high compliance reduces transmitted vibration more effectively than a stiffer mount.
A. The buffer has an M12 female thread with an overall diameter of 50 mm and a height of 30 mm.
A. Female flat buffers of this type are used across construction equipment, industrial machinery, agricultural equipment, commercial vehicles, and elevators. Relevant industries include power generation, marine, railway and mass transit, automotive, and construction and off-highway sectors.
A. The rubber-to-metal bonded construction absorbs and dissipates energy when the mount is loaded in compression, shear, or a combination of both. This cushions impact shocks from external moving components, reduces transmitted vibration, protects surrounding structures, and can improve operator comfort.
A. Yes — the range includes a 60 Shore A (5030FFB12-60) and 70 Shore A (5030FFB12-70) of the same 50 × 30 mm M12 geometry, plus larger M16 variants: 100 × 100 mm (100100FFB16), 100 × 30 mm (10030FFB16), 100 × 40 mm (10040FFB16), 100 × 50 mm (10050FFB16), 100 × 55 mm (10055FFB16), and 100 × 60 mm (10060FFB16).
A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request, along with additional and custom sizes.
