This deep groove ball bearing carries radial and moderate axial loads through a single row of balls guided by a solid brass cage (M). Bore diameter is 160.0 mm, outside diameter 240.0 mm, and width 25.0 mm, giving a net mass of 4.249 kg. The limiting speed is rated at 4950.0 1/min, with a reference speed of 2950.0 1/min. The radial internal clearance falls in group C3, providing extra internal play to compensate for tighter fits or thermal expansion during operation. The solid brass cage (M) offers stable ball guidance and mechanical strength at higher speeds. As an open, unsealed design, this bearing requires external lubrication and protection, and is suited to applications where shaft alignment and thermal growth demand the increased clearance of the C3 class.
