Conveyor Bearings for High Temp

Regreasable & High Temp Conveyor Bearings

FRANTZ built its conveyor bearing reputation on the quality and performance of its commercial grade Non-Precision bearing assemblies for conveyor rollers. Conveyor bearing lubrication is a critical component in selection decision for superior bearing performance and longevity. Most of FRANTZ Non-Precision Conveyor Bearings are offered either lightly oiled or grease packed. GENII® Semi Precision Conveyor Bearings and GenStar® Precision Conveyor Bearings are grease packed.

These situations require conveyor bearings with regreasable features.

High Temperature

Always ascertain the temperature range for conveyor bearing lubricants. But in high heat situations (above 120°F) grease starts to oxidize and oils evaporate even within the stated range of the lubricant. The degree of heat, the length of time a bearing is subjected to heat, and the movement of air over the rollers (as in a drying oven) all significantly affect the evaporation or oxidation of the oils in the grease. Further, above 300°F, the hardness of the steel components starts to degrade and will shorten the conveyor bearing life.FRANTZ has experienced good success with Molybdenum Disulfide grease for high temperature applications up to 550°F and above. However, at temperatures above 300°F, the hardness of the carbon steel components starts to degrade and will shorten the conveyor bearing life. Bearing protection is also a factor to consider when selecting for a high temperature application. FRANTZ offers metal sealing rings and labrynth shields in a number of bearings to perform in high temp applications. The table below contains FRANTZ High Temp bearing recommendations with specific features for High Temp applications.
