SKF234416MSP5Double Direction Axial Angular Contact Thrust Ball Bearing – 80 mm ID, 125 mm OD, 54 mm Total Width, Open, 60° Contact Angle, Machined Brass Cage, SP Precision.

Product Description

What this part is

234416-M-SP double-direction axial angular contact thrust ball bearing, series 2344. Bore: 80 mm. Outside diameter: 125 mm. Total width B: 54 mm. Single-component width C: 27 mm. Two ball rows, 60° contact angle, separable matched component set, open.

Decoding the designation

2344: double-direction axial angular contact series. 16: bore code, 80 mm. M: machined brass cage. SP: special precision tolerance class, held to restricted running accuracy.

What these specs mean in practice

Basic dynamic axial load rating Ca: 57.0 kN (12,810 lbf). Basic static axial load rating C0a: 173 kN (38,890 lbf). Fatigue load limit Cua: 15.7 kN. On a 60° double-direction thrust type the static rating sits far above the dynamic rating, and that is the normal relationship for this family. The 60° angle puts almost the whole load path along the axis, which is what makes this type the standard fixed bearing for a ball screw drive. Attainable speed: 4,500 r/min on grease and 6,000 r/min on oil. Axial rigidity: 640 N/µm.

Quantity and configuration

One bearing unit, supplied as a separable matched component set. Mass: 2.155 kg (4.75 lbs).

Fitting notes
