Shell Morlina S4 B 220
Shell Morlina S4 B 220 is a premium synthetic bearing and circulating oil engineered to deliver exceptionally long oil life, outstanding system cleanliness, and reliable wear protection in demanding industrial environments.
Advanced Synthetic Lubricant for Lobe Blowers, Gearboxes, and Other Industrial Systems
Shell Morlina S4 B 220 is a premium synthetic bearing and circulating oil engineered to deliver exceptionally long oil life, outstanding system cleanliness, and reliable wear protection in demanding industrial environments.
It is especially well-suited for rotary lobe blower gearboxes and bearings, where continuous operation, oxidation stability, and dependable lubrication performance are critical.
Why Choose Shell Morlina S4 B 220?
Extra Long Oil Life
Formulated with highly stable synthetic base oils and a robust oxidation and rust inhibitor system, Shell Morlina S4 B 220 helps:
- Extend oil drain intervals
- Reduce maintenance frequency
- Maintain clean lubrication systems, even at elevated operating temperatures
This makes it ideal for continuous‑duty blower and conveyor operations where downtime must be minimized.
Excellent Wear and Corrosion Protection
Shell Morlina S4 B 220 provides:
- Strong anti‑wear protection for gears and bearings
- Effective rust and corrosion inhibition for metal surfaces
This helps protect critical components and extend equipment life in moderately loaded gearboxes and circulating oil systems.
Supports Efficient Operation
The oil’s stable viscosity across a wide temperature range, combined with:
- Rapid water separation
- Efficient air release
helps maintain protective oil films and supports smooth, efficient operation in blower, conveyor gearboxes, bearing housings, and circulation systems.
Lobe Blower Applications
Shell Morlina S4 B 220 is specifically suitable for rotary lobe blower systems, including lubrication of:
- Timing gears
- Gearboxes
- Rolling and plain bearings
In continuous or heavy duty blower service, Shell Morlina S4 B 220 helps:
- Protect gear teeth and bearing surfaces
- Manage operating temperatures
- Maintain oil cleanliness over extended service periods
Important: Shell Morlina S4 B 220 is intended for blower gearboxes and bearings only. It is not designed for oil injection into the air stream of oil free blowers.
Conveyor Applications
Shell Morlina S4 B 220 is also suitable for industrial conveyor systems, including:
- Conveyor drive gearboxes
- Bearings supporting conveyor rollers and shafts
In continuous‑duty conveyor operations, it helps protect gears and bearings from wear while maintaining oil cleanliness over extended service intervals.
Suitable for Gearboxes with Internal Backstops
Due to its additive chemistry, Shell Morlina S4 B 220 can be recommended for gearboxes with internal backstops. Unlike EP gear oils, it does not promote sprag clutch slippage during reverse rotation—an important consideration in conveyor applications.
Main Applications
- Rotary lobe blowers – gears and bearings
- Bearing and circulating oil systems – plain and rolling bearings
- Moderately loaded gearboxes – including worm gears and vacuum pumps
- Lubricated‑for‑life and extended drain systems – selected sealed applications
