Methodology

OUR SOLUTION APPROACH

Generic oils fail under demanding conditions. Banesto's Lubricants Division was created to fill exactly that gap — with engineered formulations that stand up to heat, load, dust, and washout. Our approach is systematic and science-backed.

STEP 01 · GREASE
Temperature Envelope First
Temperature limits are the first gatekeeper. Our engineer always studies continuous vs peak thermal envelopes before specifying a thickener type, matching it to real-world heat, load, and uptime demands.
ASTM D2265 Dropping Point DN Factor
STEP 02 · GREASE
Thickener Trade-off Analysis
Every thickener family brings its own strengths — some fight water, some excel at high speeds, some carry heavy loads. We weigh these trade-offs so your grease is the right fit for your machine's exact duty cycle.
Water Resistance Load / EP High Speed
STEP 01 · OIL
Viscosity–Speed–Load Selection
Base oil viscosity selection is defined by DN factor (bore mm × RPM) and load class. Engineers use the viscosity–speed map to match ISO VG precisely, targeting κ ≥ 1 and elastohydrodynamic film formation.
ISO VG κ ≥ 1 ASTM D341
STEP 02 · OIL
Oil Chemistry Alignment
Polarity, oxidation resistance, and seal compatibility vary dramatically across oil families. We align oil chemistry with the duty — matching mineral, PAO, PAG, ester, or silicone on ASTM- and OEM-backed science.

FORMULATED IN THE LAB.
VALIDATED IN THE FIELD.

Every Banesto lubricant recommendation begins with kinematic viscosity testing, thickener compatibility checks, and application-specific load–speed analysis — before it ever reaches your machine.

Grease Engineering

THICKENER PROFILES

Each thickener family has a distinct performance signature. Selection is never generic — it is dictated by temperature range, speed, load, environment, and re-lubrication interval. These profiles are the starting point for every Banesto grease recommendation.

Compatibility Rule: Polyurea is incompatible with all soap-based thickeners. PTFE/PFPE is incompatible with all hydrocarbon greases. Always purge and clean bearing housings completely before changeover. Use the Grease Compatibility Checker below to assess any specific combination.
Oil Engineering

BASE OIL FAMILIES

Base oil selection defines oxidation stability, viscosity-temperature behaviour, and seal compatibility at the molecular level. Banesto engineers apply ASTM D341 viscosity-temperature modelling and OEM compatibility data to select the right base stock for every system.
