Product Number: 5021FFB10-45
Variations
Engineered to yield and absorb rather than resist, the 5021FFB10-45 Female Flat Buffer in 45 Shore A rubber delivers maximum compliance under load, making it the grade of choice where vibration isolation takes priority over restraint. At 50 mm diameter by 21 mm height with an M10 female thread, this unit is rated to a maximum load of 352 kg with a deflection of 5.00 mm, figures that reflect the inherent suppleness of the soft-grade formulation and its capacity to accommodate movement within a controlled range. Rubber-to-metal bonded construction provides the durability expected in continuous industrial service, while the flat buffer geometry suits direct-contact mounting against surfaces or as an elastic element absorbing force from an approaching component. The female thread simplifies installation and allows secure fastening without exposed male stud hardware. Softer Shore A grades are specifically suited to conditions where lower-frequency vibration isolation is the primary objective and where equipment or surrounding structures benefit from a mount that gives under load rather than bracing against it, improving machinery lifespan and protecting adjacent components from transmitted shock. This grade serves lighter or load-sensitive applications across sectors including agricultural equipment, elevators, power generation plant, marine installations, and commercial vehicles, environments where operator comfort and the protection of sensitive machinery are as important as structural support. The 45 Shore A compound deflects readily to dissipate energy before it reaches the mounting structure, reducing the amplitude of vibration reaching connected components.

A. The 5021FFB10-45 Female Flat Buffer measures 50 mm diameter by 21 mm height (D x H: 50 x 21) and is fitted with an M10 female thread.
A. This unit carries a maximum load of 352 kg and has a rated deflection of 5.00 mm, reflecting the compliance characteristics of the 45 Shore A soft-grade rubber.
A. Shore A hardness indicates rubber stiffness. At 45 Shore A, this is the softest grade in the Female Flat Buffer range, offering greater deflection under load and superior vibration isolation — particularly effective at lower frequencies and for lighter or load-sensitive equipment.
A. This buffer is suited to agricultural equipment, elevators, commercial vehicles, marine installations, and power generation plant — wherever vibration isolation and protection of sensitive machinery or structures takes priority over load restraint.
A. The flat buffer absorbs and dissipates energy either by acting as an elastic element in direct contact with a surface or by cushioning impact from an approaching component. The rubber-to-metal bonded construction ensures the rubber element remains securely bonded to its metal insert under repeated loading.
A. Yes. The same 50 x 21 mm M10 geometry is available in 60 Shore A (5021FFB10-60) and 70 Shore A (5021FFB10-70) for applications requiring higher load capacity or reduced deflection.
A. Yes. Custom sizes, stainless steel metalwork, and oil-resistant or high-temperature rubber compounds are available on request.
A. We accept all major credit and debit cards, along with PayPal.
A. Standard UK mainland delivery is 3–5 working days. Next-day delivery is available on most products and will appear as an option at checkout where eligible.
