TB1308 Triple Bonded Torsion Bush
A double bonded bush with addition of an intermediate tube which is again chemically bonded in place during the moulding & vulcanisation process.
This additional metal tube is more likely to be used in thicker rubber wall sections, it stiffens the bush and is often used in higher load applications.
Contrary to the diagram, dimensions (mm) are:
A: Bore diameter: 15.97 +/- 0.08
B: Bore length : 48.24 +/- 0.15
C: Outer tube diameter: 50.86 +/-0.06
D: Outer tube length: 38.10 +/-0.15
