CNC Turned Delrin Bearing Sleeve for Industrial and Automotive
Applications Delrin (POM - Polyoxymethylene) is an often-overlooked engineering plastic that frequently outperforms both Nylon and PEEK in many applications. It offers superior machinability, tighter tolerance capabilities, minimal moisture absorption (0.25% vs 8-10% for Nylon), and costs approximately one-fifth of PEEK. For bearing sleeves specifically, Delrin represents the optimal material choice. It features a low coefficient of friction (0.1-0.3 against steel), excellent wear resistance, outstanding dimensional stability, and sufficient stiffness to maintain bearing clearance under load. While Nylon offers greater toughness and PEEK provides higher strength, Delrin occupies the sweet spot for most bearing sleeve applications. Key Features

Frequently Asked Questions Delrin or Nylon for my bearing sleeve? Delrin offers superior dimensional stability and machinability,
while Nylon provides better impact resistance and load capacity.
For humid or wet environments, Delrin is typically the better
choice as Nylon absorbs water and may swell, potentially causing
bearing seizure. For impact-loaded applications, Nylon's higher
toughness may be advantageous. Can Delrin replace a bronze bearing sleeve? Yes, for low-to-medium speed applications (under 1,000 RPM surface
speed). Delrin sleeves are self-lubricating, lighter (1/6 the
weight of bronze), corrosion-proof, and more cost-effective to
machine. The trade-offs include lower load capacity and temperature
rating compared to bronze or steel bearings. What's the difference between Delrin and POM copolymer? Delrin is POM homopolymer with higher tensile strength, stiffness,
and fatigue resistance. POM copolymers offer better chemical
resistance to strong bases and improved thermal stability. For most
bearing applications, the differences are negligible and either
grade performs well. Do you offer PTFE-filled Delrin (Delrin AF)? Yes. Delrin AF features an even lower coefficient of friction and
is recommended for high-speed or high-PV bearing applications. It
machines similarly to standard Delrin but costs approximately 30%
more. Can you machine very thin-walled sleeves? We can machine sleeves down to approximately 1mm wall thickness on
bore diameters up to 50mm. Below this thickness, sleeve deflection
during machining makes tolerance maintenance challenging.
Alternative approaches include using thicker rod stock or
specialized tube stock for very thin walls. What's the lead time for 1,000 bearing sleeves? 7-10 days. Delrin's excellent machinability and material
availability enable production rates of 3,000-5,000 pieces per day
on a single CNC lathe for simple geometries. Additional processes
like plating or post-machining treatments may add 2-3 days. |
