Penrite Oil is a family-owned Australian manufacturer with production facilities across Victoria and Queensland.
Proudly servicing all states of Australia and across New Zealand, Penrite delivers lubricants and fluids engineered for the rigours of the heavy-duty sector – trucks, buses, tractors, and the demanding world of trucking and trailer applications.
Their heavy-duty focus is clear: lubricants that protect transmissions, hydraulics, bearings, and chassis components; ensuring smooth operation, extended service life, and reduced downtime.
Here, we spotlight three standout Penrite products tailored to trailer applications: Heavy-Duty Bearing Grease, Molygrease EP 3%, and Indus Pro Hydraulic Fluids (ISO 46 and ISO 68).
Heavy-Duty Bearing Grease
This NLGI 2 lithium-complex EP grease is crafted for severe-duty applications, a perfect match for heavily loaded trailers. It is designed to:
• Handle extreme loads and shock: Ideal for wheel hubs, suspension pivots, kingpins, and other critical bearing components.
• Resist water wash-out and corrosion, even in dusty or salty roadside environments.
• Maintain stability under high temperatures, whether from brake heat or high-speed operation.
Penrite’s Heavy-Duty Bearing Grease ensures bearings and chassis points stay reliably lubricated and protected under real-world trailer conditions, from Australia’s dusty outback to coastal salt spray.
Molygrease EP 3%
A step up when mechanical stress is at its peak. This lithium-soap grease is fortified with 3 per cent molybdenum disulfide (“moly”), giving it:
• Enhanced film strength under extreme pressure, maintaining lubrication even where ordinary greases can fail.
• Exceptional durability at high temperatures, making it ideal for CV joints, universal joints, turntables and other load-bearing pivots.
• Robust protection in exposed weather and gritty environments, critical for components outside sealed systems.
Molygrease EP 3% is invaluable for trailer components facing constant stress, weather exposure, and long intervals between service.
Indus Pro Hydraulic Fluids – ISO 46 & ISO 68
Key to hydraulic systems like brake controls, landing gear, lift gates, and stabilisers, Penrite’s Indus Pro Hydraulic range delivers:
• Excellent anti-wear and anti-corrosion protection, safeguarding pumps, valves, and hydraulic circuits.
• Low zinc content, enhancing compatibility with silver-plated components and modern hoses and seals.
• Compliance with high-level industry standards (ISO 6743 HM, DIN 51524-2 for ISO 46; plus Cincinnati Milacron P-69, Denison HF-0/1/2, Vickers I-286-S & M-2950-S for ISO 68).
• Superior oxidation and foam control, vital for consistent performance across fluctuating environmental conditions.
Selecting ISO 46 caters to lighter-duty hydraulic tasks, while ISO 68 is better suited to high-temperature or heavy-duty systems, offering reliable fluid control under pressure and load.
Why these products matter for truck trailers
In the heavy-duty world of truck trailers, maintenance windows are tight, conditions are harsh, and component failure isn’t an option. Penrite’s products rise to these challenges:
• Heavy-Duty Bearing Grease maintains integrity in heavily loaded, high-heat, or wet conditions.
• Molygrease EP 3% offers unmatched resilience in exposed, high-stress motion joints.
• Indus Pro Hydraulic Oils deliver consistent, wear-resistant performance for critical hydraulic systems – no premature failure or maintenance headaches.
