This single row deep groove ball bearing carries the designation 16044-M-C3, with a bore diameter of 220.0 mm, outside diameter of 340.0 mm and width of 37.0 mm, weighing 13.3 kg. The cage is a solid brass design (M), and radial internal clearance corresponds to C3 (Group 3), giving greater internal play than a standard clearance to compensate for operating temperature rise and shaft fit tightness. Limiting speed reaches 3400.0 1/min, with a reference speed of 2310.0 1/min. The wider internal clearance of the C3 class makes this bearing suitable for applications where thermal expansion or interference fits would otherwise reduce running clearance to unacceptable levels. The solid brass cage guides the balls with stable, low-friction contact and holds up well under the speeds this bearing is rated for. As an open bearing (no seals or shields), lubrication and contamination protection must be provided externally, and grease or oil lubrication should be selected according to the actual operating speed relative to the reference speed value.
