Our bearing houses are IP69K certified!

The IP69K rating is for applications where high pressure and high temperature washdown are used to sanitise equipment. The IP69K test specification was initially developed for road vehicles, especially those that need regular intensive cleaning, such as dump trucks and cement mixers but has been widely adopted in the Food and Beverage industries as a test of products to withstand sanitary washdown.

In the IEC 60529 rating system, IP6 refers to the product’s ability to resist ingress of dust. The 69K refers to the product’s ability to resist ingress of high temperature (Steam) / high pressure water.

How is the product usually tested?

• Products rated to IP69K must be able to withstand high-pressure and steam cleaning.
• The test specifies a spray nozzle that is fed with 80 °C water at 80–100 bar (1160-1450 psi) and a flow rate of 14–16 L/min.
• The nozzle is held 10–15 cm from the tested device at angles of 0°, 30°, 60° and 90° for 30 seconds each.
• The test device sits on a turntable that rotates once every 12 seconds.

Our bearing houses are USDA certified!

A high focus on hygienic design ensures that the bearing house can be cleaned behind and around the shaft and furthermore, NGI offers hygienic spacers to increase the distance to machines and equipment to over an inch as recommended by the USDA.

USDA Guidelines for the Sanitary Design and Fabrication of Dairy Processing Equipment: Point 23, Rotating shafts, page E 10 : ..."bearings shall be mounted to provide a minimum of 1 inch (25mm) exterior open space on the shaft between the mechanical seal for the bearing and the nearest part of the sanitary seal or the opening to the product contact area. The 1 inch (25mm) minimum space shall be open to the atmosphere and be easily accessible for inspection and cleaning."

Sum up of requriements for the USDA certification:

• 1 inch  (25mm) minimum space
• Material food approved
• Roughness maximum 1.6 Ra we are at 0.8 Ra
• Radii minimum 3.2 mm
