Product Number: 11877MCB41-45
Variations
Delivering generous deflection under load, the 11877MCB41-45 is a 118 x 77 mm conical buffer with an M16 x 41 mm male stud, moulded to a 45 Shore A hardness and designed for applications where maximum vibration isolation takes priority over restraint. At this softer end of the hardness range, the rubber compound yields 18.2 mm of deflection, making it particularly well suited to lighter or sensitive equipment where the priority is absorbing and dissipating low-frequency vibration energy rather than carrying heavy imposed loads. The rubber-to-metal bonded construction unites a vulcanised rubber cone with a steel insert to form a single, durable assembly. Conical buffers of this geometry can be loaded in compression, shear, or a combination of both, and the 45 Shore A formulation is the grade of choice where isolating delicate machinery from transmitted shock and vibration matters most. By cushioning external moving components against impact, the buffer improves operator comfort, extends machinery service life, and protects surrounding structures from cumulative fatigue. This size and grade is appropriate across a broad set of industries: primary or secondary suspension duties on industrial vehicles, vibration isolation on agricultural equipment, protection of sensitive assemblies on power generation plant, and anti-shock applications in marine, railway, and construction environments. The softer compound excels wherever transmitted vibration must be attenuated before it reaches sensitive sub-assemblies or operators. This buffer is available in 60 Shore A (11877MCB41-60) and 70 Shore A (11877MCB41-70) for heavier loads and firmer restraint.

A. This buffer has a rated deflection of 18.2 mm, which is characteristic of the 45 Shore A soft grade and makes it suited to applications requiring maximum movement under load for effective vibration isolation.
A. The outer body measures 118 mm diameter by 77 mm height. The male stud is M16 with a 41 mm thread length.
A. This buffer is used across construction and off-highway equipment, agricultural machinery, industrial vehicles (primary and secondary suspension), power generation plant, marine, railway and mass transit applications, and anywhere a soft, high-deflection mount is needed to isolate sensitive assemblies from vibration and shock.
A. Softer grades such as 45 Shore A give greater deflection and better vibration isolation at lower loads. Where carrying capacity matters more than isolation, harder grades (60 Shore A or 70 Shore A) are available in the same 118 x 77 mm size.
A. It operates by absorbing and dissipating impact and vibration energy through its vulcanised rubber cone, which is rubber-to-metal bonded to a steel insert. It can be loaded in compression, shear, or a combination of both.
A. Yes — stainless steel metalwork, oil-resistant rubber, high-temperature rubber compounds, and additional or custom sizes are available on request.
