Gravity oilers deliver oil from a vented reservoir through an adjustable needle valve to a brush applicator riding the chain surface. The flexible brush bristles follow the contour of the moving chain, spreading oil to all load-bearing pin-bushing interfaces. Drip rate is set at the needle valve and monitored through a lower sight glass without disassembly.
Use nondetergent petroleum-based oil. Detergent additives disrupt oil penetration into the pin-bushing clearances where lubrication matters most. Select SAE viscosity by ambient temperature at the lubrication point:
−20°F to +80°F
+10°F to +110°F
+20°F to +130°F
+30°F to +140°F
+40°F to +150°F
SAE 10
SAE 20
SAE 30
SAE 40
SAE 50
Fluent stocks replacement components for all gravity oiler configurations we supply.
Collect the following specifications so we can match the right configuration to your application.

Fluent builds roller chain conveyors for recycling facilities, scrap processors, aggregate operations, and other demanding applications. We use the same gravity oiler systems we sell on our own equipment every day.
When you source through Fluent, you get:
Configuration recommendations matched to your chain spec, feed count, and mounting constraints
Brush selection and oil viscosity guidance for your operating environment
The same Oil-Rite components we trust in our own custom conveyors
