Plant in Taloja used AP3 on their kiln girth gear. At 130°C, grease softened and centrifugal force threw it off within 2 hours. Two labourers doing nothing but reapplying twice per shift. AP3 was cheap — the labour and downtime cost 10x the grease.
Gel grease doesn't melt at operating temperature and doesn't fling off at operating speed. Apply once, it stays.
Non-melt: Drop point exceeds 200°C. At temperatures where AP3 turns liquid (180°C), gel grease maintains structure.
Anti-sling: Polymer tackifiers create extreme adhesion. Centrifugal force that throws regular grease off can't detach gel grease.
Shear stability: Resists breakdown from repeated gear tooth meshing.
Don't waste on standard applications — costs more than AP3. If the grease stays put (sealed housing, moderate temp), use AP3/MP3. If it melts or flings off, switch to gel.
| Application | Temp / Why Gel |
|---|---|
| Kiln girth gear | 100-160°C — heat melts regular grease |
| Crusher bull gear | 60-90°C — shock + exposed = fling-off |
| Coupling guards (packed) | 80-120°C — centrifugal force |
| Sugar mill rollers | 60-80°C — open gears, water |
| Cement mill girth gear | 80-120°C — same as kiln |
| High-temp chain drives | 100-140°C — chain oil evaporates |
| Pack Size | Best For |
|---|---|
| 1 kg tin | Trial, single point |
| 5 kg bucket | Single large gear monthly |
| 18 kg pail | Multiple machines quarterly |

Q: Gel grease vs open gear grease?
Open gear grease is bitumen-based (thicker, blacker) for very large slow girth gears. Gel grease is lighter, handles higher temps, works on gears + couplings. Gel is more versatile.
Q: Can I use gel grease on regular bearings?
You can, but it's overkill. Costs more than AP3/MP3. For enclosed bearings at normal temp, standard grease is more cost-effective.
Q: What temperature can it handle?
Continuous to 180°C. Drop point exceeds 200°C. Full performance at 100-160°C surface temperature.
Q: How often reapply on girth gear?
Every 1-2 weeks for exposed girth gears. Compare to 2-3x per shift with regular grease — interval alone justifies higher cost.
Q: Compatible with existing grease?
Clean off old grease first. Mixing with bitumen compound or lithium grease reduces performance of both.
