IE B047TEST REPORT ON XADO HIGH-TEMPERATURE GREASES
Wafer oven press: grease does not coke, units run without teardown
Grease did not coke up, units rotated freely, disassembly with grease replacement was not needed. 2.8× — grease change interval in the press units, 21 → 60 days (2001).

Key result
| OBJECT | OPERATING CONDITIONS | WHAT WAS MONITORED |
|---|---|---|
| Press No. 10 of oven No. 3 — treated | Temperature in the bearing unit zone above 200 °C, friction speed 0.1–0.2 m/s, rotation angle of the lock units up to 30° — without full rolling of the elements | Freedom of rotation, condition of rolling element surfaces, grease coking |
| 47 presses of the same oven — control | Same process and same period on the standard “Shell” grease | Condition of the friction units at inspection |
| Fan bearing supports of the cracker line, biscuit shop | Continuous three-shift operation, Litol-24: servicing every 7 days, bearing life to failure 6 months | Treated on 21.05.2001 — bearings 32308 and 6308 |
Press No. 10 and the control presses of the same oven — 500 hours of operation
| WHAT WAS ASSESSED | PRESS No. 10 — XADO GREASE | CONTROL PRESSES — STANDARD GREASE |
|---|---|---|
| Condition of the grease in the units | No traces of coking either on the friction surfaces or on the bearing parts | High degree of grease coking |
| Mobility of the units | Free rotation, no seizing | Loss of mobility of the bearing units and, as a result, disruptions in equipment operation |
| Surfaces of the rolling pairs | Smooth polished surface covered with a metal-ceramic layer | Friction units coked |
| Grease change | Not required over 60 days of testing (500 h of operation) | Disassembly with soaking or replacement every 3 weeks |
The treated press and the 47 control presses of oven No. 3 ran in the same process and over the same period — at a temperature in the unit zone above 200 °C.
Conclusions of the plant commission
Current equivalent
Revitalizant gel for compressors and bearings →
Piston, screw and centrifugal compressors; rolling and sliding bearings running in an oil bath; machine-tool spindle units and slideways.
How such units are treated:
Limits of this report: The results apply to bearing units of wafer oven presses operating at a temperature in the unit zone above 200 °C, at low friction speeds and without full rolling of the rolling elements; under other conditions the figures may differ.
