High temperature over long periods of time, sudden changes from high to low temperatures, continuous humidity - for equipment and especially for bearings, conditions in the brewery are a constant threat. Moreover, the placenta should work in these difficult conditions while ensuring a satisfactory level of hygiene and sterility.

To meet the situation, international bearing concerns SNR (France) and NTN (Japan) propose bearings and bearing units designed specifically for breweries. The proposed solution combines efficient operation at high and low temperatures, increased resistance to contamination while maintaining health and food safety standards.

Regardless of the quality of the ingredients used in the food industry, there are times when products are inedible because of the mechanical ingredients, especially because of the bearings. Such situations occur because the operating environment of the bearings is subject to many different factors - it combines many difficulties, therefore the bearings must also have special properties, such as resistance to corrosion, contamination or ease of decontamination.

Continuous optimization of high and low temperature performance, surface integrity maintenance and component cleanliness - SNR took all these factors into account to create bearings specifically designed for the malting and brewing industries:

• Standard bearings with automatic lubrication
• SNR bearings with grease.
• Two piece cast iron bearing units.
• Thermoplastic self-aligning bearing units.
• Self-aligning stainless steel bearings.
• Self-aligning cast iron bearing units.
• Spherical Roller Bearings - EF 800 Series.
• Spherical roller bearings with steel cage.
• Ball bearings (high and low temperature) - Topline series

NTN offers a complete series of easy-to-use bearings and bearing units specifically designed for the food industry. They combine a sterile design that allows easy cleaning and effectively prevents the spread of bacteria. They are made of safe materials and meet the standards of the food industry.

• NTN bearings with grease.
• NTN bearings with food grade high temperature grease.
• Stainless steel grease NTN bearing units for the food industry.
• NTN bearing units with plastic housing and grease for the food industry.
• Units with triple gasket bearing.

Standard bearings and SNR automatic lubrication

SNR offers a full range of standard ball and needle roller bearings. Any type of machine using a standard open bearing and lubrication system can be improved by an automatic lubrication system. SNR AL1 grease for the food industry meets the strictest health and cleanliness requirements today.

Automatic lubrication provides:

• Consistent, even lubrication.
• Reduction of maintenance work related to the operation of equipment in a hazardous environment and reduction of maintenance costs.
• Visual assessment of proper grease dosage.
• Wide versatility of use.

SNR bearings with grease. SNR grease contains a mesh of porous polymer, capable of holding 3 to 4 times more oil than conventional grease, for longer bearing life. 

• Eliminates downtime and the need for re-lubrication.
• Grease for the environment and food contact.
• operating temperature range: -20 ° C or -50 ° C to + 80 ° C or + 100 ° C.
• Can be used with any type of seal: plate, rubber as well as with open bearings (ball, spherical, tapered).

NTN Bearings Grease

Grease is a unique method of lubricating bearings, which contains grease and polyethylene macromolecules. Before it is placed in a bearing, it resembles ordinary grease, but when heated and cooled, it solidifies to a solid state with a resin-like appearance. Bearings are usually filled with this type of grease in the minimum amount necessary to lubricate the bearing. This method is known as: spot-packing

Properties:

• Will not stain due to leakage of grease around the bearing.
• Water will not emulsify the lubricant or make it start
