HPE High Temperature EP Grease: Guide for KL & Selangor Industries
HPE High Temperature EP Grease: Guide for KL & Selangor Industries
What is HPE High Temperature EP Grease and why is it suited for Kuala Lumpur & Selangor?
HPE High Temperature EP Grease is a lithium‑based extreme‑pressure lubricant rated for continuous operation up to 180 °C, with a dropping point near 260 °C. Its EP additives form a protective film under load, preventing wear in hot, humid climates where standard greases degrade quickly.
It is commonly used in industries such as steel mills, rubber processing, and textile machinery where sustained heat accelerates lubricant breakdown.
What are the key properties and specifications of HPE High Temperature EP Grease?
HPE High Temperature EP Grease is NLGI grade 2 with a base oil viscosity of 220 cSt at 40 °C and a dropping point of approximately 260 °C. It operates from –20 °C to 180 °C, shows a wear scar under 0.4 mm in the four‑ball test, and passes ASTM D3336 and D942 for oxidation and water resistance.
- NLGI grade: 2
- Base oil viscosity: 220 cSt @ 40 °C
- Dropping point: ~260 °C
- Operating range: –20 °C to 180 °C
- Four‑ball wear scar: <0.4 mm
- Oxidation stability: ASTM D3336
- Water resistance: ASTM D942
What benefits does HPE High Temperature EP Grease offer in high‑temperature environments?
In temperatures above 150 °C, HPE High Temperature EP Grease retains its structure, resists oxidation, and continues to lubricate bearings and gears. This reduces downtime, extends re‑lubrication intervals, lowers maintenance costs, and can cut frictional losses in heated gearboxes, saving energy.
Users report longer service life for pillow‑block bearings and fewer unexpected breakdowns in continuous‑duty equipment.
Where should HPE High Temperature EP Grease be used in Kuala Lumpur & Selangor industries?
HPE High Temperature EP Grease is ideal for heat‑exposed equipment such as conveyor bearings, crane hoists, motor bearings, and automotive wheel hubs in Kuala Lumpur and Selangor factories. It is not suitable for food‑contact points unless a food‑grade grease is used instead.
Manufacturing and heavy machinery
In manufacturing lines, the grease is pumped into pillow‑block bearings, gearboxes, and slide ways where friction and ambient heat raise temperatures. Its high dropping point prevents melt‑out, while the EP additive film shields gears from shock loads during peak production shifts.
Regular re‑lubrication according to OEM recommendations helps maintain optimal film thickness and prevents premature bearing failure.
Automotive and transportation applications
Automotive workshops in Kuala Lumpur and Selangor apply HPE High Temperature EP Grease to wheel bearings, CV joints, chassis pivots, fifth‑wheel couplings, and trailer axle bearings. The grease’s water‑resistant EP layer protects against corrosion and wear, extending service intervals for fleets and private vehicles.
It is also suitable for electric motor bearings that operate under load and ambient heat.
Food processing and pharmaceutical
HPE High Temperature EP Grease is not formulated as a food‑grade lubricant and must be avoided where incidental food contact is possible. For clean‑room or pharmaceutical equipment requiring NSF H1 certification, users should select a dedicated food‑safe grease instead to prevent contamination and regulatory issues.
Always verify the lubricant’s certification before applying it to sensitive production lines.
How to select and apply HPE High Temperature EP Grease correctly?
Select HPE High Temperature EP Grease by matching the equipment’s operating temperature range, load characteristics, and NLGI grade 2 requirement. Apply it with a grease gun or centralized system, ensuring full cavity fill while avoiding over‑pressurization that could damage seals, and always clean old grease first.
Choosing the correct NLGI grade ensures proper pumpability and sealing performance in your specific application.
Step‑by‑step application guide
Follow these six steps to apply HPE High Temperature EP Grease correctly: clean the housing with a compatible solvent, inspect seals and replace if worn, pump grease until fresh appears at the purge port, rotate the shaft to distribute lubricant, wipe excess to avoid dust attraction, and record the service date for future maintenance planning.
- Clean the bearing housing and remove old grease with a compatible solvent.
- Inspect seals and replace if worn.
- Pump the recommended amount of HPE High Temperature EP Grease until fresh grease appears at the purge port.
- Rotate the shaft manually to distribute the lubricant evenly.
- Wipe excess grease from the housing exterior to avoid attracting dust and debris.
- Record the re‑lubrication date and operating hours for future maintenance planning.
What are the compatibility and storage tips for HPE High Temperature EP Grease?
Store HPE High Temperature EP Grease in a cool, dry place below 30 °C, away from sunlight and contaminants. It is compatible with most mineral‑oil greases but should not be mixed with silicone or polyurea types without testing. Discard if hardening, discoloration, or odor change occurs.
- Storage temperature: <30 °C, dry
- Avoid direct sunlight and moisture
- Keep container tightly sealed
- Do not mix with silicone or polyurea greases without prior testing
- Shelf life: approx. 24 months from manufacture
Frequently Asked Questions (FAQs)
What is the maximum operating temperature for HPE High Temperature EP Grease?
The grease is designed for continuous operation up to 180 °C, with short‑term spikes tolerable up to 200 °C. Exceeding these limits may cause dropping point failure and loss of EP protection.
How often should I re‑lubricate equipment using this grease in a tropical climate like Malaysia?
In hot, humid conditions, a typical re‑lubrication interval ranges from 500 to 1,000 operating hours for heavily loaded bearings. Regular temperature and vibration monitoring can help adjust the schedule to actual wear.
Is HPE High Temperature EP Grease compatible with centralised lubrication systems?
Yes, its NLGI grade 2 consistency and pumpability make it suitable for most progressive and dual‑line centralized systems. Ensure the system’s pressure settings do not exceed the grease’s recommended limit to avoid seal damage.
Can this grease be used on electric motor bearings in Kuala Lumpur factories?
Absolutely; the grease’s low noise characteristics and high temperature stability make it ideal for electric motor bearings subject to load and ambient heat. Always verify the motor manufacturer’s lubrication specifications before application.
Where can I purchase genuine HPE High Temperature EP Grease in Selangor?
Authorized distributors and industrial suppliers across Selangor stock the product, and you can also order directly online via the HPE High Temperature EP Grease product page. Buying from reputable sources ensures you receive the correct formulation and proper documentation.
