MRC212MMaximum-Capacity Filling-Slot Ball Bearing – 60 mm ID, 110 mm OD, 22 mm Width, Open, Pressed Steel Cage

Product Description

What this part is: MRC 212-M maximum-capacity filling-notch single-row ball bearing. Bearing Type: maximum capacity, filling notch. Bore: 60 mm (2.3622 in). Outside Diameter: 110 mm (4.3307 in). Overall Width: 22 mm (0.8661 in). Closure Type: open, both faces. Number Of Rows: 1. Rolling Elements: ball. Cage Type: two-piece ball-riding stayrod cage. Cage Material: pressed steel. Dynamic Load Rating: 56,100 N (12,600 lbf). Static Load Rating: 51,000 N (11,500 lbf). Limiting Speed: 4,900 rpm on grease, 6,000 rpm on oil. Maximum Shaft or Housing Fillet Radius: 1.5 mm (0.06 in). Internal Clearance: ABMA C0. Series: MRC 200 Light. Decoding the designation: 2 — the MRC 200 Light Series. 12 — bore code, multiplied by five to give Bore: 60 mm. M — maximum capacity, filling notch. What these specs mean in practice: Dynamic Load Rating: 56,100 N. Static Load Rating: 51,000 N. The filling notch cut into one shoulder of each ring lets more balls into the raceway than a Conrad assembly of the same envelope holds, and that extra ball complement is where the radial capacity comes from. Bearing Type: maximum capacity, filling notch. The notch interrupts one shoulder of each raceway, so the type carries its load radially and its thrust capacity is small beside its radial capacity. That is the trade the design makes. Limiting Speed: 4,900 rpm on grease, 6,000 rpm on oil, rated for the pressed steel cage at ABEC 1. Internal Clearance: ABMA C0. Maximum Shaft or Housing Fillet Radius: 1.5 mm — the largest corner radius on the shaft shoulder or housing bore that the bearing corner will clear. Quantity and configuration: Unit Quantity: 1 Pc. One open bearing. Interchange guidance: Searchable variants of the number: 212M, 212-M, 212 M, MRC 212M. NSK BL212 is the maximum-type filling-slot bearing in the same 60 x 110 x 22 mm size. The Conrad bearing on that envelope is a different design with an uninterrupted raceway and different capacities, so it is a related size rather than a like-for-like substitution. MRC 212-S is the Conrad deep groove bearing in the same series and bore, and 213-M is the next bore up in the same maximum-capacity range.
