Tilton Engineering 61-8122 Ultra-Low Profile 8000-Series Hydraulic Release Bearing 44mm

The Tilton Engineering 61-8122 is an ultra-low profile 8000-Series hydraulic release bearing (HRB), also known as a hydraulic throwout bearing, designed for high-performance racing clutch applications. This precision-engineered component features a 44mm radius-face contact bearing diameter with a billet aluminum construction measuring 1.44 inches tall, making it Tilton's lowest-profile hydraulic release bearing available.

Key Features:

• Ultra-low profile design with flush-mount 2-bolt mounting pattern for use with transmission adapters
• Constant contact design provides immediate clutch response and ensures the system is always ready to engage
• Self-adjusting mechanism automatically compensates for clutch wear to maintain consistent pedal feel
• Proprietary low-friction surface coating for enhanced durability and high-performance operation
• Unique multi-edged quad-tension monoseal technology tested to hundreds of thousands of actuations
• Resilient wiper seal prevents bore damage from debris contamination
• High-quality bearings extensively tested for long-life durability
• Piston area: 1.221 square inches (788 square mm)

Applications:

The 44mm bearing size is compatible with Tilton OT-II (7.25") and most Quartermaster 4.5", 5.5", and 7.25" racing clutches. Ideal for applications requiring very low profile assembly and typically mounts onto the transmission or bellhousing using an appropriate adapter (sold separately).

Important: Always use a clutch pedal stop with hydraulic release bearings to prevent pedal overtravel, which can cause pressure spikes that may damage clutch fingers or thrust bearings.
