Stewart Golf, a leading manufacturer of luxury golf trolleys, turned to Spirol Industries to solve an engineering design problem when axle pins holding its wheels in place were shearing.

Compression limiters preserve joint integrity
Spirol compression limiters are used to preserve a threaded joint's integrity when fastening plastic-to-plastic assemblies or plastic-to-metal assemblies.
Compression limiters protect plastic threads
Solid knurled compression limiters preserve the integrity of a plastic threaded joint when a metal bolt is inserted, preventing creep, loosening and eventual failure of the joint.
Stewart Golf was using the CLDP pin as a stop pin to prevent the movement of a plastic wheel centre, with the rubber attached to outside rim, from moving about on the bottom axle of the trolley.
It was in this application that premature shearing was being experienced.
The pin was shear and hardness tested and conformed to all expected levels.
However, Spirol found that two issues were affecting the performance of the pin.
First, the plastic wheel centre had a curved hole against which the pin lay flat.
Secondly, the hole in the shaft into which the pin was being pushed was counter bored.
This reduced the amount of material around the length of the pin and therefore the amount of radial tension the pin could achieve was reduced.
Spirol advised Stewart Golf to omit both of these counter bores in the next prototype.
The result has been a further 20kN strength on the pin and it now performs as expected.
Stewart Golf is now dealing directly with Spirol Industries and the advantages are clear: full the engineering support and application advice, a fully traceable product and a range of standard range off-the-shelf pins. Request a free brochure from Spirol Industries ...
