Single Row Ball Bearing With Angular Contact Seal

The Single Row Ball Bearing With Angular Contact Seal is a rolling bearing that combines an angular contact structure with a sealing design. It can simultaneously withstand radial loads and unidirectional axial loads, and is suitable for rotary systems that require high precision, low friction, and protective performance. Its core design optimizes the load distribution through the contact angles (usually 15° and 25°) between the single - row steel balls and the inclined raceways, and is equipped with a sealing structure to resist the intrusion of contaminants.
Structural Features
Single - row Angular Contact Design
The single - row balls are arranged at a specific angle (α = 15°/25°) to achieve a dynamic balance between radial and axial loads.
The cage - less design (full - complement type) can increase the limiting speed and load - carrying capacity.
Sealing Protection System
It is equipped with built - in double - lip rubber seals (2RS) or metal labyrinth seals (Z/ZZ).
The precise fit between the sealing lip and the shaft shoulder forms a double - protection barrier.
Materials and Processes
It is made of bearing steel (SUJ2/GCr15) or ceramic balls (Si₃N₄).
The vacuum quenching process makes the hardness reach HRC62 - 64, and the surface roughness Ra ≤ 0.2μm.
