FAG234430MSPDouble Direction Axial Angular Contact Thrust Ball Bearing – 150 mm ID, 225 mm OD, 90 mm Width, 60° Contact Angle, Machined Brass Cage, SP Precision

Product Description

What this part is

FAG 234430-M-SP double-direction axial angular contact thrust ball bearing. Bore 150 mm, outside diameter 225 mm, overall width 90 mm. Series: 2344. Two ball rows, 60° contact angle, machined brass cage, open, straight bore. Country of origin: Germany.

Decoding the designation

2344: double-direction axial angular contact ball bearing, the series machine-tool builders use for the axial position of a precision spindle or a ball screw. M: machined brass cage. SP: Schaeffler special precision, the accuracy grade above standard for this family. Contact Angle: 60°.

Published ratings

Dynamic load rating: 176 kN (39,566 lbf). Static load rating: 550 kN (123,645 lbf). Limiting speed: 3,200 rpm. Operating range: −30 °C to 120 °C. Mass: 28.5 lb. Lubrication: oil.

What these specs mean in practice

A 60° contact angle puts almost all of the load path into the axial direction, so this bearing sets and holds the axial position of a spindle or screw under heavy thrust with very high stiffness. Two rows facing opposite ways take that thrust in both directions from a single unit, which is why the static rating stands far above the dynamic rating on this family — short, heavily preloaded ball paths resist indentation long past their fatigue-life figure. SP accuracy holds axial runout tight, which is what keeps a machined face flat and a screw axis true.

Quantity and configuration

One double-direction bearing unit. Unit quantity: 1 Pc.

Fitting notes

Straight 150 mm bore. Oil lubrication suits the speed and the 60° geometry. Axial clamping is applied through the ring faces so the two rows share the thrust as designed.
