Long-lasting bearing solution for freezing tunnel applications

Produced for Premier Is
Bakery & Sweets

Premier Is is one of the oldest dairies in Denmark. During peak season, they produce up to 270 pallets of ice cream each day. After the ice cream is produced, and just before packaging, it is transported into a freezing tunnel which is -34°F.

Accumulation of moisture in the bearing houses solved with NGI bearings

Premier Is has had a problem with moisture accumulating when cleaning with hot water, which is then being drawn into the bearing houses. The contamination of the lubricant with water due to the accumulated moisture jeopardizes the functionality of the bearing, resulting in a significant increase in wear.

”Premier Is has tested the hybrid bearings from CeramicSpeed — which bearing houses from NGI can be fitted with — and achieved four times (or even longer) bearing life while reducing downtime and operational costs."

Premier Is

The Challenge

The bearings are fitted in turning wheels located at each end of a freezing tunnel (-34°F) to guide the hundreds of feet of chain slowly transporting the products in a bottom-to-top spiral route. Moisture accumulates when cleaning with hot water, and the moisture is sucked into the bearing houses. The contamination of the lubricant with water due to the accumulated moisture jeopardizes the functionality of the bearing, resulting in a significant increase in wear.

The Solution

The issue of moisture accumulation and bearing contamination can be mitigated with the use of a hybrid CeramicSpeed bearing, which can be installed in NGI bearing houses. The material properties of these bearings make them less susceptible to damage from this problem when compared to standard steel bearings.

In addition, the IP69-K-certified bearing houses from NGI have a unique, patented sealing system that is waterproof at more than 3° misalignment, minimizing the risk of moisture entering into the bearing house in the first place.

The Effect

Premier Is tested the hybrid bearings from CeramicSpeed — which bearing houses from NGI can be fitted with — and achieved four times (or even longer) bearing life while reducing downtime and operational costs.
