Purpose and fit

These rubber spacers measure 50 mm outer diameter, 12 mm inner diameter and 20 mm thickness. The pack contains four pieces suited to machinery, furniture, appliances and automotive uses where vibration damping and height adjustment are needed.

Behaviour under load

The rubber material is described as tough, wear-resistant, waterproof and elastic, resisting cracking, shrinking and deformation over time. It maintains its shape and damping performance during sustained compression in industrial or household equipment.

Thermals, noise and power

As passive rubber components they generate no heat, draw no power and produce no noise. Their non-slip surface helps stabilise mounted items while absorbing shock in normal operation.

Questions about this item

How much vibration and heat do these 50 x 12 x 20 mm rubber spacers transmit when machinery runs continuously?

The rubber material absorbs shock and dampens vibration effectively, while its elastic, non-slip properties reduce heat transfer between mounted equipment and the surface.

What shaft or bolt diameter must my equipment have for the 12 mm inner diameter to fit correctly?

The spacer fits a 12 mm (1/2 inch) inner diameter, so your bolt, shaft or mounting stud must match that size for a secure, centred fit.

Will the 20 mm thickness and 50 mm outer diameter align with the mounting pattern on my older industrial brackets?

Each washer measures 50 mm outer diameter by 20 mm thick, matching the stated 2 x 13/16 inch profile; verify your bracket hole spacing and clearance against those dimensions.
