About the Product

SURLOCK 638 Dynamic Retainer is designed to give High Strength Retention under Cyclic loading. SUR638 will retain its full strength and not suffer fatigue under load stress.


SUR638 is a cylindrical parts supplement, suited to Structural components such as cylindrical parts under dynamic load, keys, splines, even structural tubing with close tolerance fit.

Useful Hints/Notes

Surface keying action is greatly increased by rough surface finish, giving higher Shear Strength. Ideal roughness is between 10-120 microns with a preferred tolerance of between 30-100 microns. The larger gaps over 175 microns can result in Ultimate Strength loss.


Fast Hold:…………………….   5-7 mins @ 25C
Short Ultimate Cure:………… <6 hours
Achieving 30N/mm(2) Static Shear
