KT Needle Bearing for Engine Crankshafts
KT Type Needle Roller Bearing
High-Performance Bearings for Engine Crankshafts
Overview
The KT type needle roller bearing is specifically designed for the big-end or lower end bore of the connecting rod in engine crankshafts. This type of bearing operates eccentrically around the engine output shaft, with centrifugal forces significantly increasing at higher rotational speeds. Therefore, the structural strength of the cage requires special reinforcement.
The cage of the KT type bearing is made of SCM 415 chrome molybdenum alloy steel, which undergoes heat treatment and shot peening to enhance fatigue strength.
Key Features
- Heat Treatment: Carbonitriding treatment for superior hardness and wear resistance.
- Hardness (roller): HRC 60-66, ensuring reliability under high-load operating conditions.
- Dimensional Tolerance: Needle outer diameter tolerance precisely maintained at +0 / -0.002mm.
