PRODUCT DETAILS
About QJ328
Product structure:
Outer ring and inner ring: chromium bearing steel, GCr15, GCr15SiMn, GCr6, GCr9, etc.; stainless steel, AISI 440C
Rolling element: high carbon chromium steel, AISI 52100; ceramic, alumina (Al2O3) and silicon nitride (Si3N4)
Product Features：
Multi-directional load bearing: can bear radial and axial loads at the same time.
High speed: suitable for high-speed equipment.
Contact angle: different angles (such as 15°, 25°, 30°, 40°) affect the axial load bearing, and high-precision bearings often use 15°.
Paired configuration: often used in pairs (back-to-back, face-to-face or in series) to adapt to different loads.
