Description
This needle roller bearing carries radial loads without an inner ring, giving a compact cross-section within an outside diameter of 125.0 mm and a width of 35.0 mm. The single-row design has a net mass of 0.745 kg, a limiting speed of 4400 1/min and a reference speed of 2650 1/min, built to DIN 617/ISO 1206. Radial internal clearance is CN (Group N), the standard clearance class, paired with a standard cage. The bearing has no seals, so lubricant supply and contamination protection must be arranged externally, and a separate shaft with a hardened and ground raceway is required for correct operation.
