ISOTROPIC SUPERFINISHING
Any of our Ring & Pinion gears can be ordered “polished” using our in-house Isotropic Superfinishing process.
Simply put, Isotropic Superfinishing significantly reduces the surface imperfections that remain after a Ring and Pinion Gear set is manufactured. The result is a cooler, quieter and longer lasting gear set. At West Coast Differentials, the process we use is chemically accelerated vibratory surface finishing. This is technically not a polishing process, however the resulting finish does have a polished appearance. This process eliminates surface imperfections without removing material or changing the physical dimensions of the part.
This finishing process is widely used in racing applications where a conventional break-in process is not feasible, and where optimum performance is not an option.
BENEFITS of ISOTROPIC SUPERFINISHING
- Reduced Friction
- Reduced Contact Wear
- Reduced Heat
- Increased Durability
- Improved Oil Retention
- Lower Operating Temperature
- Reduced Noise & Vibration
- Increased Fuel Economy
- Reduced Break-In Requirements
- Reduced Maintenance
