Baoxing Food‑Grade Chain Oil, High‑Temperature Resistant & Anti‑Dripping


With stricter regulations in the pet‑food industry, manufacturers face higher requirements for equipment safety and material protection. 


As production capacity of baked and extruded pet food expands, belt and multi‑layer dryers run 24/7.

Lubrication of conveyor chains directly determines production stability and food safety.


Chains inside dryers operate continuously under high‑temperature conditions with heavy feed dust. Hidden friction points on chain pins and sleeves absorb dust particles during operation. 

There is also a risk of oil dripping onto pet‑food materials, a critical safety concern for pet‑feed processors.


Ordinary industrial chain oil oxidizes rapidly at high temperatures. Residues mixed with dust form carbon deposits and sludge.

Coking jams chain links, resulting in noise, extra friction, 

skipped teeth and chain‑off faults. Unplanned shutdowns for chain cleaning cause heavy production losses.


Non‑food‑safe high‑temperature oil creates contamination risks once leakage occurs, failing compliance inspections. 


Many regular food‑grade chain oils suffer fast carbon build‑up, requiring frequent re‑lubrication and raising maintenance costs.

Baoxing BX‑308/A‑WY food‑grade high‑temperature chain oil is specially formulated for conveyor chains on belt‑type and multi‑layer pet‑food dryers.


  • Excellent thermal‑oxidation stability, low evaporation loss at high temperatures.

  • Penetrates chain pins and sleeves to form durable lubricating films and reduce wear.


  • Strong anti‑coking performance, minimizes sludge and carbon accumulation, lowers chain‑cleaning frequency.


  • Superior adhesion, resists dripping and splashing during long‑time continuous operation to reduce feed‑contamination risk.


Certified by NSF H1, FDA, RoHS and REACH. Compliant with pet‑feed safety standards. 

Suitable for belt dryers, multi‑layer dryers, tunnel baking lines for pet‑food, bakery and general feed‑processing conveyor chains.


As an experienced specialty food‑grade lubricant manufacturer, 

Baoxing provides one‑stop services: lubrication selection consultation, 

free sample testing, maintenance‑schedule formulation and on‑site technical guidance for pet‑food and food‑processing production lines.
