Certified Hygienic
Bearing Houses

Custom and standard bearing housing solutions

NGI offers a wide assortment of bearing units that fit into most industrial and production setups. Our bearing housings are made in high quality materials, creating a reliable product that requires zero maintenance or lubrication through its lifetime.

The insert bearings are mounted securely in the housing, protecting it from damage and contaminants. This makes our bearing housings suitable for most environments, especially when high hygienic standards are a requirement. This is especially useful for the food or pharmaceutical industries, but any production environment requiring high hygienic standards can benefit from our bearing housings.

Are you looking for heavy-duty bearing housings? Our bearing housings have been designed with durability and strength in mind. The entire unit can withstand temperatures from -20ºC (-4 degrees Fahrenheit) to +110°C (230 degrees Fahrenheit). Moreover, the bearing unit is built to last, and we have rigorously tested our bearing units, so that they can easily withstand the pressures and forces during its operation in your specific setup.

Avoid fretting corrosion: Lubricate during mounting of bearing houses

Fretting can occur between the shaft and the inner ring for stainless bearings especially when they are mounted dry (without lubricant in between).

A high-viscosity lubricating paste is the most important thing. Other things that increase the risk of fretting are a loose fit and not properly tightened set screws, misaligned bearings, and internal forces from poor mounting.

Lubrication:
When the bearing and shaft are mounted without lubrication, there is an increased risk of fretting*. This results in dust causing damage to the spherical seal and the seal of the bearing and ultimately causing the bearing to break down. Any lubrication can be used, but we recommend the following: SKF Anti-Fretting Agent LGAF 3E. The LGAF 3E anti-fretting agent from SKF has been designed to prevent fretting corrosion caused by slight oscillations and vibrations.

Bearings are easier to dismount after applying the smooth paste made from a mineral and synthetic base oil type. The anti-fretting agent also assists with the removal of general components such as, nuts, bolts, flanges, studs.

*Fretting corrosion
Fretting corrosion is movements between two metal surfaces. In this way, metal particles are worn free and oxidize immediately. Oxidized iron particles can destroy shape tolerances on the shaft or housing, which can lead to serious damage to the bearing.
To ensure that the bearing assembly is carried out optimally in the first instance, NGI recommends that before assembly you must be very careful with cleaning the shaft, avoid dirt on the bearing itself and to use an assembly paste between the shaft and the bearing.
