The SY65 Bottom Roller is a high-quality excavator undercarriage component engineered to provide stable ground contact, smooth track movement, and dependable support for medium-size excavators. Designed for SY65 excavators, this track roller delivers excellent durability and consistent performance in construction, mining, earthmoving, and other demanding applications.
The SY65 bottom roller is engineered with premium alloy steel materials and optimized heat treatment technology to achieve excellent durability. The hardened roller shell maintains strength and dimensional stability during prolonged operation, reducing replacement frequency and improving machine uptime.
Designed for challenging job sites, the SY65 track roller provides reliable performance under conditions involving mud, dust, rocks, vibration, and continuous heavy loads. The reinforced construction helps resist wear, impact damage, and structural fatigue.
The induction-hardened contact surface effectively reduces abrasion caused by constant track chain movement and ground contact. This wear-resistant design helps extend roller service life and maintain consistent undercarriage performance.
The precision-ground raceway ensures smooth contact between the roller and track chain, improving track alignment and reducing vibration. Stable support helps minimize uneven wear on other undercarriage components.
The floating Duo Cone seal prevents contaminants such as dust, water, mud, and abrasive particles from entering the internal bearing chamber. Combined with permanent lubrication, it ensures smooth rotation and reduced maintenance requirements.
The SY65 Bottom Roller is suitable for:
