4.Material: Inner ring / outer ring / isolation ring: GCr15/GCR15SIMN, rolling elements (steel balls): GCr15/GCR15SIMN, cage: brass.
5.Accuracy: Conventional P0 grade, precision models are of P6/P5/P4 grades.
6.Application Fields: Machine tool spindles (bidirectional positioning), large motors, transmission ends of port cranes, precision reducers.
7.Key Inspection Items: Consistency of double-row steel ball clearance (deviation ≤ 0.002mm), accuracy of bidirectional contact angles, radial runout, running stability.

Product Description

Double Row Angular Contact Ball Bearings for Extreme Load & Precision Scenarios

When your equipment demands bidirectional load handling and space-efficient precision, double row angular contact ball bearings deliver unmatched performance. Designed with two rows of balls and optimized contact angles, these bearings eliminate the need for paired arrangements while handling combined axial and radial loads. At LUOYANG INNO BEARING, we create ball bearing solutions that thrive in metallurgy, wind energy, and robotics.
