Product Introduction
The HCST2749 is a precision compact tapered roller bearing engineered to handle high radial and thrust load combinations in space-restricted assemblies. Featuring exact dimensions of 27 x 49 x 15 mm, this bearing is widely utilized in motorcycle steering columns, light automotive gearboxes, and precision auxiliary drives. Manufactured in our automated production facility using high-purity GCr15 bearing steel, the HCST2749 features precision-ground raceways and micro-finished rollers to ensure low friction, reduced operating temperatures, and extended service life under frequent vibration and direction changes.
Applications
Motorcycle steering stems and chassis pivot points.
Light utility vehicle gearboxes and steering boxes.
Compact industrial speed reducers and power equipment.
