SF-1 Plain steel bushing is a type of DU bushing. It's also called teflon bearing,DU bush and PTFE lined dry sliding bearing,SF-1 bearing,oil free bushes. SF-1 self-lubricating bearing has a common structure with other DU bearing.

Material structure:


   

  1. PTFE/Pb mixture 0.01~0.03mm as sliding layer, provides an excellent initial transfer film, which effectively coats the mating surface of the bearing assembly, forming homogeneous oxide type solid lubricant film.
  2. Porous bronze 0.2~0.3mm, provides Max. thermal conductivity away from the bearing surface, also serves as a reservoir for the PTFE-lead mixture.
  3. Low-carbon steel backing 0.7~2.3mm, provides fundamental structural support and gives exceptionally high load carrying capacity, excellent heat dissipation.
  4. Tin-plating 0.005mm or copper plating 0.008mm, provides good corrosion resistance.

Characteristics:

  • Good wear and friction performance over a wide range of loads, speeds and temperature without oil
  • Also perform well with lubrication

Maintenance-free, long life

Availability:

  • Standard cylindrical bushing, flanged bush, thrust washers and strips are available.
  • Lead free type is also available

EVA Faux Teak Sheet

EVA Faux Teak Sheet comes in double layers EVA material, it appears grooves to show the bottom color after the roller cutting, which makes it looks like a teak wood. So instead of using a real wood for the boat flooring, more and more people put their focus on this no maintain and Eco-friendly EVA marine sheet.

EVA Faux Teak Sheet

Made from marine grade UV resistant, closed cell, high density EVA foam material, it stands perfectly even in a strong sunlight area. And the EVA foam material makes it softer and more comfortable for people standing there bare feet than real teak or PVC teak. Some would concerned if the boat mat would be not durable to use since it is made from foam material. Well, it may not hard like real teak or PVC teak, and compete the durability with those two, but with a higher density EVA foam, we are able to compete with other suppliers who try to compromise the density to reach to a lower price.


The sheet comes in 230cm x 90cm or 250cm x 120cm, user can cut the sheets into size to fit the shape of boat decking, then just peel and stick since the sheets we offer is with 3M adhesive on the backing. It can be applied on boat decking of course, and other like swim platform pad, helm station pad or simple seat pad.

EVA Faux Teak Sheet

What's more, this kind of sheets can be applied in recreation vehicle for luxury flooring, a safe traction mat for the edge of swimming pool, a beautiful looking for flooring in room or balcony.
