Food MachineryComponent Guide

NTN Food Machinery ComponentsAs customer needs for food preparation have become increasingly diverse, demands regarding the taste, price,

and variety of food have become more stringent. A wide variety of dedicated food-processing machines have beendeveloped to deal with this trend and to contribute to the design of more advanced food-processing centers.

NTN offers a full line of easy-to-use mechanical components optimized for food processing machinery.Significantly, they incorporate hygienic design to allow for easy washing and effectively prevent bacteriapropagation. As well, they are made of safe materials that comply with the USDA (U.S. Department of Agriculture)and other food standards.

Bearing Units/Food Machinery Ball Bearings

3.1 Bearings with solid greaseSolid grease is a unique solid bearing lubricant that essentially

comprises lubricating grease and super molecular weightpolyethylene. Before being packed into a bearing, it resemblesordinary grease. However, once heated and cooled, it solidifiesand takes on a solid resin-like appearance. Spot packing is thestandard lubricant prefill system. The cage is provided withgrease at several spots.

a) Bearings with solid grease for general use (P-03)¡Features(1) More resistant to centrifugal force-induced leakage.(2) Fouling from grease leaks on or around the bearing is

positively prevented.(3) Water does not emulsify the grease or cause the grease

to leak. Thus, the grease has a longer lubricating life.(4) Unlike ordinary grease, bearings with solid grease

exhibits virtually no stirring drag and thereforecontributes to lower bearing torque.

¡Permissible operating temperature range and speedTemperature at bearing outer ring: Use the bearing in a temperature range of －20˚C to 80˚C(60˚C max. for continuous operation).Permissible dn value: 120 000［dn=bearing bore diameter d(mm)×operating speed n (min-1)］

¡Applicable bearingsBall bearings for bearing units, with a maximum borediameter of 140 mm (models UC, UK, AS, CS)Grease code: LP03

b) Bearings with solid grease for food machinery (P-06)¡Features

In addition to the advantages of the general-use bearingswith solid grease (P-03) as mentioned in a) above, bearingswith solid grease type P-06 boasts a high degree of safetybecause its heat-solidifying grease for food machinery iscomposed of food-grade lubricating grease that complieswith the USDA's H-1 standard (permitting contact with food)and super molecular weight polyethylene approvedaccording to an FDA (US Food and Drug Administration)standard.

6 Triple-Sealed Bearings for Bearing Units

6.1 Features¡Better dustproofing and waterproofing ensures longer

bearing life.The triple-sealed bearing is provided with a triple-lippedbearing seal. The special seal offers reliable dustproofingand waterproofing superior to those of standard bearingsfor bearing units. It therefore ensures longer service lifeeven under conditions of heavy airborne dust and dirtysplashing water.

¡Reduces maintenance cost.With a longer bearing life than ordinary bearings used in unitconfigurations, these bearings have longer maintenance intervals,greatly reduced maintenance costs (for inspection, relubrication,replacement, etc.), and increased productivity of machines.

¡Decreases price of bearing unit and allows for much more compact machinery.Under certain operating conditions, the triple-sealed bearingunit can replace conventional covered bearing units, greatlydecreasing the cost of bearing units. Furthermore, if the coveris not needed, machinery can be made much more compact.

¡Balled setscrew ensures secure fasteningThe triple-sealed bearing is mounted on the shaft withNTN's unique balled setscrew, which has an embeddedball in its tip. This setscrew boasts much greater resistanceto loosening than serrated or cup-point setscrews, anddoes not readily loosen due to vibration or impact.

¡InterchangeabilityThe triple-sealed bearing unit conforms to the JIS standard forUC-type bearings. It can be readily used as a relubricablebearing, and can replace NTN's conventional bearing unit andother manufacturers' products. It can therefore easily be used toreplace existing bearing units during machinery maintenance.

Triple-sealed bearings with secure dustproofing /waterproofingProvides a longer service life even when exposedto heavy airborne dust and splashing water.

6.6 Special specification bearing unitsThe standard products of this series are prelubricated with

lithium mineral grease. Contact NTN Engineering forinformation on optional bearings, such as those containingPolylube (heat-solidifying grease) or food-grade grease, andstainless steel bearings.

7.1 FeaturesStandard bearings cannot be used in environments where

they will be exposed to water or liquid chemicals. In contrast,NTN resin rolling bearings can operate without relubrication, ata lower torque in such environments because their inner andouter rings, balls, and cage are made of unique corrosion-proofself-lubricating materials.

Note, however, these bearings must be used at a lower load rating andlimiting speed because their inner and outer rings are made of resin.

Constant velocity

joint

After installation, the joint assembly must be used at a fixed location, or may be transported within a very limited distance.

Note:The constant velocity joint is a rotating mechanism. Before using it in an environment requiring protection from contamination by foreign matter, cover the joint to prevent it from emitting any foreign matter.

Remarks:The above flowchart should be used for joint selection. However, a different selection process may be required for applications with non-standard operating conditions. In such a case, contact NTN Engineering for technical assistance.
