Optional corrosion coatings and grease lubrication system.

Corrosion protection for Combined Bearings:

All Winkel Combined Bearings are available with ATC-armoloy coating on request

ATC is a low-temperature, multistate metal finishing process based on chrome-plating technology.  Unlike conventional chrome-plating ATC-armoloy utilizes proprietary chemical solutions and application processes that are carefully monitored to produce its thin dense chromium coating which follows the exact contours of the metal with accurate deposit thickness.

Advantages of using ATC-Coating:

  • Resistant to corrosion – the surface is inherently hard and the coated bearing surface becomes smoother
  • Long life – ATC-coated surfaces have a lower coefficient of friction and get no oxidizing.
  • Chromium coating and hardness – 99% pure chromium, 72 HRC hardness

Corrosion protection for Profiles:

All Winkel steel profiles are available in a corrosion-protected version.  They will be delivered completely machined and galvanised ready to mount.

The following coatings are available for profiles:

  • Chemical galvanised – up to 3 mtr lengths, white or yellow galvanised version
  • Plasma galvanising – Completely welded constructions with the profiles are available in coated version. Plasma galvanised surfaces are superior to normal zinc coatings.  The thickness of the coatings varies from 0.1 – 0.3mm depending on whether the use is land or offshore conditions. The use of Winkel combined bearings will not crack off the coating.

Lubrication:

  • activator (6 months red, 12 months grey)
  • lubrication system with high-performance grease WHF 04
  • bracket (stainless steel)
  • nylon tube L = 2000 mm
  • tube connection M6
  • grease nipple R ¼ (for pre-filling of the tube)
