SKF234420BM1SPDouble-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.
