Description
Gym weight plate isolation washers
Gym weight plate isolation washers provide high-performance shock absorption to eliminate the low-frequency impact and noise of returning selected gym stacks.
Core Benefits & Function
- Impact Reduction: Specifically engineered to dampen the strong kinetic “thump” of heavy weight plates striking the selector base plate.
- Material Composition: These acoustic washers made from Sylomer have been designed for the insulation of gymnasium machinery. The advanced cellular polyurethane material yields far superior lifespan and damping compared to generic rubber rings.

Options & Material Specifications
Select from three density profiles, across two thickness options, based on your machine’s total stack profile:
| Type | Colour | Static Load (kg) | Thickness (mm) | Code |
| Washer SR-110 | Brown | 30 | 12 | 707824 |
| Brown | 30 | 25 | 707819 | |
| Washer SR-220 | Red | 50 | 12 | 707825 |
| Red | 50 | 25 | 707820 | |
| Washer SR-450 | Grey | 100 | 12 | 707826 |
| Grey | 100 | 25 | 707821 |
Dynamic Loadings and Configuration Guide:
When at rest, washers bear a purely static load equal to the physical weight sitting directly above them. However, as the weights descend under momentum, they produce a much higher dynamic force.
To handle this spike without bottoming out, use a configured system of four total washers spread evenly across your two guide bars using these exact material pairs:
We suggest the following combinations, of four washers, spread over two guide bars:
| 0kg-75kg | 75kg-130kg | 130kg-200kg |
| Brown | Red | Grey |
| + | + | + |
| Red | Grey | Grey |
Essential Installation & Maintenance
- Safety First: It is essential to make sure the weight stack is supported with a rigid safety buffer whilst installing these washers. Never work beneath an unsecured stack.
- Maximum Damping System: For premium noise isolation, combine these guide-rod washers with specialized floor mounting solutions like our TSR IsoPads, placing 3 or 4 isolated pads beneath the structural floor feet of the selector machine framework.
