Resin Chocking

Steel chocking has the disadvantages that each block must be individually fitted, a time consuming process, and after fitting are susceptible to fretting and wear. Resin chocks are poured and therefore are much quicker to apply. They form into the shape of the clearance and key into surface imperfections. This much reduces damage due to fretting and removes bending momemts on the holding down bolts.
The disadvantage is that the resin creation must be precise and that it is less straight forward to replace in the event of damage of misaligenement.

Properties

The material used for the rsin chocking is Class tested to ensure minimum standards.

A sample cured in the correct way is tested for the following;
1. The impact resistance
2. Hardness.
3. Compressive strength (stress at maximum load) and modulus of elasticity.
4. Water absorption.
5. Oil absorption.
6. Heat deflection temperature.
7. Compressive creep
8. Curing linear shrinkage.
9. Flammability.
