Novenco Bronze Filled Wear Strip Roll
Our Bronze Filled PTFE compound provides great light-duty, low friction performance.
NEC - 07
NOVENCO produces, Tight Tolerance, PTFE Bearing Tape that is designed to eliminate scoring in Hydraulic and pneumatic cylinder applications by preventing metal to metal contact. Our Bronze Filled PTFE compound provides great light-duty, low friction performance.
NOVENCO possesses the expertise to make the best quality skived PTFE products in the market today. Precision crafted in to rolls; our Bearing Tapes are made with the latest skiving. Technologies and premium selection of Raw materials. Our Bearing Tapes can be produced from 0.063' up to 0.125' thick (from 1.5 to 4mm), in widths from 0.25' upto2' (from 3 to 49.8mm).
The process of ordering is very simple- just select a Thickness (C/S) and the Width (L2). Don't forget to double check your Groove Width for clearance (L1). The roll length will be determined by the Thickness(C/S).

Note: G min controls the minimum metal-to-metal clearance between the gland and rod or between bore and piston. G max controls the maximum extrusion gap seen by a seal associated with the bearing. Typically, G min should be 0.70 mm (0.0280 in) but can be reduced when required by the extrusion gap for the seal and the build-up of tolerances. The absolute minimum metal-to-metal clearance recommended is 0.10 mm (0.004 in). More information can be found in the Housing Designs and Extrusion Gaps pages at the front of the catalogue. For applications not using a seal G max, see part number range in the following pages
