This page sorts high-temperature greases by the continuous operating temperature limit stated in the TDS, with the thickener, the base oil and the H1 registration where there is one; the last section covers high-temperature chain oils for stenters, ovens and board presses. Send the temperature measured at the bearing housing and the machine type; a Hop Tien engineer selects the grease within 24 working hours.
"High-temperature grease" has no general meaning: each grease has a continuous operating limit stated in its TDS, and that limit depends on the base oil and the thickener. Lithium greases on mineral oil stop at 120–140 °C; polyurea and lithium complex greases on synthetic oil reach 160–200 °C; silicone/PTFE greases up to 220 °C; PFPE/PTFE greases 250–260 °C; above that, use an ester chain oil or solid lubricants. Choose a grease whose continuous limit is above the temperature measured at the bearing housing by a safety margin, keep the same thickener as the old grease or clean out when changing, and choose the base-oil viscosity by speed. The color of a grease says nothing about its temperature capability.

Temperatures per the TDS of each product. The bearing-housing temperature at steady running is markedly higher than the ambient temperature; measure with an infrared thermometer before choosing, do not use the chamber set-point.
The continuous limit in the TDS must be above the temperature measured at the bearing housing by a safety margin: a grease running close to its limit dries out quickly and must be relubricated more often; the short-term limit in the TDS is for a few hours only. PFPE greases do not mix with other greases. For high-speed bearing greases see the separate page. Check the four points below before every grease selection or change:
Chains on stenters, ovens, steamers, board presses and oven conveyors work at temperatures where grease no longer stays in place; use a low-volatility, low-residue synthetic ester chain oil.
| Chain oil | Base oil / viscosity at 40 °C | TDS temperature | Used for |
|---|---|---|---|
| TURMOFLUID 40 B | Ester/SHC · 270 mm²/s | −20…300 °C | Stenter chains, dryers, oven conveyors; case study: 8-chamber stenter |
| TURMOFILMOIL HTC 300 | Ester · 370 mm²/s | up to 260 °C | High-temperature chains and rails, long-lasting oil film |
| TURMOSYNTHOIL HTC 220 · HTC 320 | Ester · 228 / 330 mm²/s · H1 registered (InS) | up to 250 °C | Oven and steamer chains in food plants |
| TURMOWOODOIL 1 · 2 · 2-100 | Ester / SHC · 250 / 54 / 107 mm²/s | up to 250 °C | Continuous board presses: steel belts, chains, bending bars |
| TURMOFLUID LMI 300 · TURMOSYNTHOIL 75 TF | Ester · 15 / 42 mm²/s · NSF H1 registered | −10…220 · −15…180 °C | Chains and guides in high-temperature food machinery |
When changing to an ester chain oil, deposits from the old oil loosen during the first weeks and can block the nozzles; heavily fouled chains should be cleaned first. Technical article: oven chain oil.
Conveyor chains, spiral freezers and packaging machines in food plants need a chain oil that flows at sub-zero temperatures and is H1 registered; this group is separate from the high-temperature chain oils above.
| Chain oil | Base oil / viscosity at 40 °C | TDS temperature | Used for |
|---|---|---|---|
| CASSIDA CHAIN OIL 150 | Synthetic · 150 mm²/s · NSF H1 registered, ISO 21469 | −30…140 °C | Drive and conveyor chains in food processing and packaging machinery |
| CASSIDA CHAIN OIL LT SPRAY | Synthetic · 32 mm²/s · NSF H1 registered · aerosol | −50…140 °C | Chains, slide guides and couplings in spiral freezers and freezing equipment |
A synthetic polyurea grease such as LUBCON TURMOGREASE N 2 MF (−40…200 °C) or N 4602 PLUS (−30…180 °C, short-term 220 °C); food plants use CASSIDA GREASE HTS 2 (NSF H1 registered, −30…200 °C). The 200 °C must be the temperature measured at the bearing housing, not the chamber set-point.
Lubricating greases stop at about 260 °C (PFPE/PTFE greases such as TURMOTEMP II/400 KL). Above that, the base oil evaporates completely and only solid lubricants remain, or an ester chain oil up to 300 °C (TURMOFLUID 40 B) is used. The 500 °C figure on some packaging is the temperature the remaining solids withstand, not the grease.
The color comes from additives and dyes and says nothing about temperature capability. Read the temperature range in the TDS and the thickener; two greases of the same color can differ by 100 °C in their limit.
Measure the temperature at the bearing housing with the motor running steadily. For ordinary 2-pole and 4-pole motors, a synthetic polyurea grease (TURMOGREASE CAN 1002, N 2; −40…160 °C per TDS) has enough margin and is stable at that speed. Keep the same thickener as the factory grease if the motor is under warranty.
Preferably. Polyurea, lithium, calcium sulfonate and PFPE greases mixed together can soften or harden; the safe way is to dismantle and clean the bearing, or to purge continuously until all of the old grease is out and shorten the relubrication interval during the first month.

Temperature, viscosity and registration data are given per the manufacturer's TDS published on each product page; the actual conditions of the machine decide the final choice. Machine makes and trademarks named on this page belong to their respective manufacturers.
