ADVANTAGES OF HARP BEARINGS

• The use of effective seals (including an X-SHIELD tight seal).
• Increased precision in manufacturing the working surfaces of bearing parts, thereby reducing noise and vibration.
• Improved vacuum-treated steel for bearings.
• Optimized radius of the raceways, which allows increasing the dynamic bearing capacity and, consequently, their durability.
• Superfinishing surface treatment.
• High precision ball. Roller with modified contact.
• Optimized separator.
