This double row angular contact ball bearing carries radial and axial loads in both directions within a single unit, using X-life optimized internal geometry for increased load rating. Bore diameter is 17.0 mm, outside diameter 40.0 mm, width 17.5 mm, and net mass is 0.096 kg. The bearing is fitted with metal shields on both sides and uses a steel sheet metal cage (JH). Limiting speed is 14600 1/min, reference speed 16600 1/min. The C3 internal clearance suits applications with elevated operating temperature or interference fits requiring extra radial play. Metal shields protect the raceway and rolling elements from coarse contamination while allowing grease relubrication is not intended, as shields are not full contact seals. The double row design provides stiff axial guidance in both directions from a single bearing position, reducing the need for a paired bearing arrangement where axial space is limited.
