Mackay M13201855 20 x 18 mm Duro 55 Multibuffer Stainless Steel

The Mackay stainless steel Multibuffer is the type 304 stainless steel version of the Multibuffer rubber buffer, which Mackay designed for control of vibration, shock and acoustic noise and describes as equally adaptable for controlling impact or for use as simple machine feet (manufacturer-stated). Mackay says the Multibuffer face profile is designed to provide a simple slip resistant surface while maintaining optimum impact and static properties (manufacturer-stated).

This listing covers 7 part numbers from 20 x 18 mm to 50 x 35 mm, all Duro 55, with M6, M8 and M10 threads. Each stainless part number shares a table row with a standard Multibuffer part number (for example M13201855 and M12201855), and the dimensions and load figures are the same. The catalogue lists a static load from 25 kg to 157 kg and a buffing load from 53 kg to 316 kg for these sizes.

Mackay notes that stainless steel studs are not available for the Multibuffer (manufacturer-stated).

Common specifications

Key specifications

Dimensions are in millimetres: A is the diameter and B is the height, as read from the catalogue diagram, and C is the metric thread size. The load columns use Mackay's own headings (Static and Buffing, each with Load in kg and deflection in mm). Mackay prints all properties as nominal and asks you to contact them for technical advice. Mackay lists each stainless part number in the same row as its standard counterpart, so the figures are those of that row.

Selecting the right option

Choose the buffer by load first. Each part number has its own static load and buffing load, each with its own deflection, so work out the load each buffer carries and stay within the figure that matches how you use it. Because the figures are nominal, confirm critical loads with Mackay. Mackay notes that stainless steel studs are not available, so confirm how you will fix the buffer before you order and contact Mackay if you are unsure. The stainless part numbers stop at 50 x 35 mm; for larger buffers see the standard Multibuffer linked below.
