Deep groove ball bearing 6305-2Z-L207-C3 carries radial and moderate axial loads on a single row of balls guided by a steel sheet metal cage (JN). Bore diameter is 25.0 mm, outside diameter 62.0 mm, width 17.0 mm, and net mass is 0.25 kg. Both sides are fitted with shields, keeping the raceway protected while allowing regreasing through the shield clearance. Limiting speed reaches 13700 1/min, with a reference speed of 12300 1/min. Radial internal clearance is C3, above the standard range, which compensates for tighter fits or thermal expansion during operation without introducing excessive play. The steel sheet metal cage keeps ball spacing stable at the stated speed range, and the shielded design limits contamination ingress while retaining the internal grease fill. The bore type Z indicates a cylindrical bore matching standard shaft tolerances for this diameter.
