Case Study: Reliable, Quality Feel for E-Brake Switch
Background
As vehicles incorporate increasingly sophisticated electric component designs, more lubrication points are required to ensure lasting, trouble-free operation. An Automotive Tier 1 Supplier approached one of Nye's affiliates in search of a lubricant for their Electronic Parking Brake (EPB) switch. The supplier needed a plastic-compatible grease that would prevent wear, reduce noise, and convey a quality feel within their switch’s mechanical design.
Challenge
Can the lubricant extend the life of the switch while imparting a quality feel to improve the driving experience?
Solution
Rheolube® 362HB
A lithium soap thickened, light viscosity, synthetic hydrocarbon grease
- Reduces noise, vibration, and harshness for a quality feel
- Compatible with most plastics and elastomers
- Stable over a wide temperature range, -40 to 125°C
- Ideal for sliding or rolling components
| Product | Chemistry | Temperature Range (°C) | Oil Separation (ASTM D-6184) | Evaporation (NYE CTM) |
|---|---|---|---|---|
RHEOLUBE 362HB |
PAO/Lithium Soap | -40 to 125 | 2.2% | 0.1% |
Results
After in-house testing, the automotive tier supplier was pleased that Rheolube® 362HB reduced surface wear during EPB operation and met the functional life requirements of the OEM. The supplier was also pleased with the improved tactile feel provided by the grease.
