DELRIN ® CASE STUDY
Delrin ® – for Linear Actuator Parts in Hospital Beds
Fatigue resistant and cost-saving solution for highly
loaded linear actuator systems.
A customer switched from metal to Delrin® 51HSE for linear actuator gears in hospital beds to reduce costs
while meeting extended service lifetime and elevated max loading capacity requirements.
What did the customer gain from Delrin®?
• Reliable performance due to Delrin’s high fatigue resistance
(surpassing 3000 test cycles with up to 8,000N loading)
• Quiet performance (< 50 dB) due to inherent lubricity
• Cost reduction and up to 40% weight reduction compared
to metal gears
• Thermal stability to withstand gear box temperatures of 70-80°C
“In durability testing, Delrin® 51HSE
Cycles to failure
endures 2.5 times more load cycles
than the Delrin® 100 grades and
10 times more than high viscosity
acetal copolymer.”
