| | | GMT - Bolster Springs | | |
| | | |
| | | • Description of parts and functions: GMT bolster springs are used for high pressure loads. Therefore, they are especially ideal for the bedding of stone crushers, tandem axles, and dollies. For these purposes, oil and age-resistant elastomers are used. As a rule, these bearings are built in in pairs, as you can see from the assembly diagram below. | | |
