SKF6234MASP53S1Deep Groove Ball Bearing – Straight Bore, 170 mm ID, 310 mm OD, 52 mm Width, Open, Machined Brass Cage, P5 Precision, C3 Clearance, Heat Stabilised to 200°C

Product Description

What this part is

FAG 6234MAS.P53.S1 single-row deep groove ball bearing. Series: 62. Bore: 170 mm. Outside Diameter: 310 mm. Width: 52 mm. Open both faces, straight bore, machined brass cage.

Decoding the designation

62 is the light dimension series and the bore code 34 gives a 170 mm bore. MAS is a machined solid brass cage. P53 is a combined code: P5 dimensional and running tolerance together with C3 radial internal clearance. S1 is the heat stabilisation code, with the rings dimensionally stabilised for service to 200 °C.

What these specs mean in practice

Dynamic Load Rating: 225 kN (50,582 lbf). Static Load Rating: 224 kN (50,357 lbf). Fatigue Load Limit: 9.6 kN. Limiting speed: 3,800 rpm. Reference speed: 2,950 rpm. Calculation factor f0: 15.3. A deep groove ball bearing carries radial load and moderate thrust in either direction from a single row of balls. The P5 tolerance holds bore, outside diameter and running accuracy tighter than the normal class, which cuts runout and gives closer shaft location. The C3 clearance group is larger than normal, and pairing P5 with C3 is deliberate: tight tolerances for location, extra internal clearance to absorb a press fit and the thermal growth of the inner ring. The S1 stabilisation is what makes the 200 °C rating usable, since untreated bearing rings lose dimensional stability well below that. The machined brass cage carries the speed and temperature that a pressed steel cage would not.

Quantity and configuration

One bearing, open on both faces.

Fitting notes

Interchange guidance

Searchable variants: 6234MAS.P53.S1, 6234-MAS-P53-S1, 6234MASP53S1, 6234MAS P53 S1, 6234M, 6234. Schaeffler’s current designation on this envelope is 6234-M-C3, which carries the same 170 x 310 x 52 mm boundary dimensions, the same solid brass cage and the same C3 clearance at the normal tolerance class. The 6234-M is the CN clearance version and the 6234-M-C4 the wider-clearance version, both related sizes.
