Mackay M16911 Snubbing Washer for M169 Dual Compression Isolators, 44 mm

The Mackay M16911 is the snubbing washer used with the Mackay M169 dual compression mobile isolator. Mackay says it is supplied with the M169 only (manufacturer-stated), so this listing is for the washer on its own.

When the nut is tightened against the snubbing washer, Mackay says the rebound shoulder is formed automatically and the resulting pre-compression gives optimum performance (manufacturer-stated). The catalogue drawing shows a dished washer 44 mm across.

Where this product is used

• With the M169 dual compression mobile isolator (M16940, M16950, M16960) to form the rebound shoulder (manufacturer-stated).
• Providing fail safe assembly when the dual compression isolators are installed with suitable washers (manufacturer-stated).

Features

• Forms the rebound shoulder automatically when the nut is tightened against it (manufacturer-stated)
• Pre-compression from tightening the nut against the washer gives optimum performance (manufacturer-stated)
• Supplied with the M169 only; included in the K versions M16940K, M16950K and M16960K (manufacturer-stated)

Fitting

• Lubricate the isolator and the socket with water, then seat the isolator in the socket (manufacturer-stated).
• Tighten the nut against the snubbing washer so the rebound shoulder forms and the isolator is pre-compressed (manufacturer-stated).
• Tighten the nut to pull the mounting bracket and snubbing washer firmly against the inner member (manufacturer-stated).

About this listing

The Mackay catalogue gives no weight or material for the washer and prints it only in the dual compression mobile isolator section, so those details are not listed here.

Key specifications

Selecting the right option

Use this washer with the M169 isolators. The K versions (M16940K, M16950K, M16960K) already include a snubbing washer, so you only need this part to replace one or to add it to a plain M16940, M16950 or M16960. Use it as Mackay shows in the mounting diagrams and tighten as described in the fitting notes. Mackay prints all properties as nominal and asks you to contact them for technical advice.
