Looking for a Toyota C-HR 2.0L CVT Main Pulley Bearing (B37-15UR) with exact factory fitment and long-lasting reliability? This main pulley bearing (37×88×19 mm) is engineered to strict OEM standards and designed specifically for the Toyota C-HR 2.0L equipped with a CVT transmission, ensuring smooth operation, reduced drivetrain vibration, and dependable long-term performance.

🔩 Precision Engineered for CVT Performance

The main pulley bearing is a critical component in a Continuously Variable Transmission (CVT), supporting the primary pulley’s rotation and helping deliver seamless gear ratio changes without steps or shocks. Manufactured with high-grade materials and precision tolerances, this bearing helps:

• Maintain smooth pulley rotation under load

• Reduce friction and heat in CVT assembly

• Enhance transmission responsiveness and efficiency

• Extend CVT service life and reduce wear

The B37-15UR bearing measures 37×88×19 mm, matching the exact specification required for proper performance in the C-HR’s CVT main pulley.

🛠 OEM-Level Quality & Fitment

Made using precision machining and durable bearing steel, this bearing is built to Toyota’s factory standards for performance and durability. It integrates seamlessly with the vehicle’s original transmission input components, including:

• CVT main pulley race and travels assembly

• Transmission housing interfaces

• Lubrication pathways and seals

Accurate fitment ensures proper preload, stable alignment, and balanced operation—helping prevent uneven wear, vibration, or premature failure.

🚗 Why Replacement Matters

Owners typically replace the CVT main pulley bearing due to symptoms such as:

• Transmission noise (whine or rumble at idle / under load)

• Vibration or harsh sensation through drivetrain

• Unstable CVT response or unusual shifting behavior

• Increased heat or friction within transmission assembly

• Bearing wear or chatter detected during inspection

Installing an OEM-compatible main pulley bearing restores original smoothness, reduces noise, and helps prolong the life of your CVT system.

⚠️ Avoiding Incorrect Parts

Using an incorrect or incompatible bearing can lead to:

• Poor alignment and uneven wear

• Transmission noise or clunking

• Accelerated pulley and belt wear

• Heat build-up and transmission failure

• Costly repairs and decreased reliability

Selecting the correct bearing specification is essential for maintaining long-term CVT performance, smooth driving comfort, and transmission durability.

✅ Before purchasing, always verify the vehicle model (Toyota C-HR 2.0L), transmission type (CVT), and bearing specs (37×88×19 mm, B37-15UR) to ensure precise fitment and dependable performance you can trust.
