Large food manufacturers typically use a portfolio of high quality NSF-registered food-grade lubricants rather than one universal grease. The selection normally depends on the equipment, load, temperature, water exposure, food-contact risk and OEM requirements.
There is no single grease that is correct for every production-line application.
What types of food-grade grease are commonly used?
A large food manufacturing site may need several lubricant types, including:
-
General-purpose food-grade bearing grease
-
High-load and extreme-pressure grease
-
Water-resistant grease
-
High-temperature grease
-
Chain lubricant
-
Spray grease
-
Silicone grease for seals and O-rings
-
Direct-food-contact lubricants where appropriate
This is why lubricant rationalisation can be valuable: the goal is not necessarily to reduce every product to one grease, but to reduce unnecessary duplication while ensuring every application has the correct product.
Why don't large plants use one food-grade grease?
Because production lines contain very different assets.
Consider a typical food plant.
-
A conveyor bearing might experience water and washdown.
-
An oven chain may experience extreme temperatures.
-
A gearbox may require a particular oil viscosity.
-
A valve seal may require silicone grease.
-
A heavily loaded bearing may require extreme-pressure performance.
-
Trying to use one lubricant across all of these applications can create avoidable performance problems.
What does a high-performance food-grade grease look like?
For demanding bearing applications, a grease should be assessed against:
-
Load
-
Temperature
-
Water resistance
-
Wear protection
-
Speed
-
Compatibility
-
Relubrication requirements
-
NSF classification
Foodcare Longlife is an example of a fully synthetic NSF H1 grease specified for ball, roller and plain bearings. It has an NLGI 2 viscosity and a temperature range of between -40 to 220 degrees C.
What about chains and conveyors?
Chains and conveyors can require a different lubricant strategy from bearings.
Activate Foodcare Spray Grease is a fully synthetic clear grease, designed for light-to-medium load applications including chains, sprockets, bearings, open gears and conveyors. It is NSF H1 registered and has a stated temperature range of -40°C to +170°C.
For slat conveyors, Activate Foodcare Slatglide is a specialist NSF H1 lubricant intended for slat conveyors and conveyor chains. Activate positions it as an alternative to water lubrication, helping create a drier production environment.
What about seals and O-rings?
Seals have different requirements from bearings.
A silicone grease can be appropriate where compatibility with rubber seals and sealing performance are important.
Activate Foodcare Sealcare is a fully synthetic silicone grease for seals and O-rings, and a stated operating range of -20°C to +220°C. It is NSF H1 registered and WRAS approved.
Do large manufacturers rationalise their lubricant ranges?
Yes, lubricant rationalisation can be a useful part of a larger asset-care strategy.
Too many products can create:
-
Stockholding complexity
-
Application confusion
-
Misapplication risk
-
More training requirements
-
More opportunities for incorrect relubrication
Activate specifically highlights product rationalisation and the reduction of ambiguity as part of its lubrication approach.
The key takeaway
Large food manufacturers typically use a controlled range of food-grade greases and oils matched to specific applications.
The objective is not to find one “universal” grease. It is to create a rationalised lubrication system in which each critical application has a clearly specified, correctly identified and appropriately registered lubricant.
That is ultimately more useful than simply choosing the cheapest or most widely marketed food-grade grease.
