⚙️Product Description:
The MH-P16-2RS / ACB4052 (40x52x7mm) is a precision angular contact bicycle headset bearing featuring a 45-degree inner chamfer and 45-degree outer chamfer (45°/45°). Engineered with high-grade GCr15 chrome steel raceways, high-precision steel balls, and dual NBR contact seals, this specialized headset unit smoothly absorbs combined axial, radial, and steering torque loads while completely eliminating fork play in integrated frame head tubes. We supply our cost-effective proprietary RMO brand MH-P16-2RS bearings alongside flexible global brand sourcing solutions for bicycle component importers, OEM frame builders, and repair distributors.
