SKF234420-BM1/SPDouble-Direction Angular Contact Thrust Ball Bearing – 100 mm ID, 150 mm OD, 60 mm Width, 60° Contact Angle, SP Class

Product Description

What this part is:

SKF 234420-BM1/SP double-direction angular contact thrust ball bearing. Bore: 100 mm. Outside diameter: 150 mm. Width: 60 mm. Series: 2344. Two rows of balls run at a 60° contact angle against a common double-sided shaft washer, so the unit carries heavy axial load in both directions.

Decoding the designation:

234420: series 2344, bore code 20, 100 mm bore. BM1: machined brass window cage, ball-guided, for high-speed spindle service. SP: restricted running-accuracy and dimensional tolerance class used on machine-tool spindles and screw drives.

What these specs mean in practice:

A 60° contact angle sets the load line close to the bearing axis, which is what gives this family its axial rigidity and a static capacity well above its dynamic rating. Basic dynamic axial load rating: 68 kN. Basic static axial load rating: 229 kN. Limiting speed: 5,000 rpm on oil, 3,800 rpm on grease.

Quantity and configuration:

One double-direction bearing unit, 1 Pc. The 2344 series is separable and the housing washers and shaft washer are a matched component set supplied together.

Fitting notes:

Straight bore, open on both faces. The ring set is ground to give its axial preload as assembled. The shaft washer is clamped between a shaft shoulder and a locknut, and both housing washers seat square in the bore.

Interchange guidance:

FAG 234420-M-SP shares the same 100 x 150 x 60 mm envelope, 60° contact angle and SP tolerance class. NSK 100TAC20D is the equivalent double-direction thrust unit in the NSK range. Searchable forms of the number: 234420BM1SP, 234420 BM1/SP, 234420-BM1-SP.
