Further information on UHMWPE Rod

UHMWPE rod is an amazing engineering plastic which can solve many problems that other engineering plastics cannot. UHMWPE Rod is not as well-known as other plastics but is still highly important and has clear advantages over other more common engineering plastics.

Manufacturers produce engineering plastics that are slightly oversize in either diameter and/or thickness. This oversize tolerance, which is listed in the tables below, is provided to assist customers to produce very accurate items within the size shown and remove any minor surface imperfection.

UHMWPE Rod Tolerances:

Nominal Diameter Tolerance in mm
10 +0.1 to +0.6
12 +0.2 to +0.7
15 +0.2 to +0.8
20 - 25 +0.2 to +1.5
30 - 35 - 40 - 45 +0.2 to 1.8
50 - 55 +0.3 to +2
60 - 70 - 80 - 90 - 100 - 110 +0.3 to +2.5
125 - 130 - 140 +0.4 to +4
150 +1 to +5.8
160 - 180 +1.2 to +7.4
200 +1 to +10

Application for UHMWPE Rod:

  • UHMWPE rod is usually chosen for it's low co-efficient of friction and so means it will produce bearings, bushes or pulleys that are highly free running, low friction and durable
  • UHMWPE rod is also remarkably abrasive resistant. Therefore the UHMWPE rod can be used in high demand environments such as grit or gravel and have a longer life span when compared to other materials
  • UHMWPE rod can often be used in high demand components in the food industry because it has a very low moisture absorption. UHMWPE rod has FDA approval and means that bearings etc. will not expand due to any moisture absorption
  • UHMWPE rod is used in the marine industry for pulleys because of its low friction and minimal moisture absorption

Availability of UHMWPE Rod:

There is a good range of sizes commercially available in both natural/white and black.


Our UHMWPE Rod or Ultra High Molecular Weight Polyethylene rod has an extremely low co-efficient of friction which offers excellent sliding properties and is one of the greatest plastics that have abrasion resistance. UHMWPE rod is tough and impact resistant including at low temperatures, it has a low weight, and is easy to weld but difficult to bond.
