Why Angular Contact Ball Bearings?

Unlike deep groove bearings, angular contact ball bearings have raceways displaced relative to each other, so they support combined radial and axial loads in one direction — and, in pairs or double-row form, in both directions. They run at higher speeds with controlled preload, making them the standard for precision spindles.

Contact angle & mounting:

Note: Dynamic load rating (Cr) and static load rating (Cor) are calculated from nominal dimensions per ISO 281; limiting speeds are reference values for grease / oil lubrication. Double-row ratings use two rows and stainless (S) ratings use AISI 440C. Figures are for preliminary selection only — confirm exact values against our official catalog before ordering.

FAQ

What contact angle should I choose?

15° (C) for high speed, 25° (AC) for a balanced speed/load mix, 40° (B) when axial load dominates. Tell us your speed and axial-load figures and we will recommend.

Can you supply matched paired sets?

Yes — 72xx/73xx can be supplied as factory-paired duplex sets (back-to-back or face-to-face) with matched preload for spindle accuracy.

Do you make double-row angular contact bearings?

Yes — 32/33 series (and legacy 52/53) carry combined bi-directional loads in one unit, no separate pairing required.

What about stainless or sealed versions?

S-series in AISI 440C for corrosive environments; B-series are factory-sealed (2RS/ZZ) and lubricated for life for maintenance-free motors and fans.

What is your MOQ and lead time?

Standard sizes: 1000 sets/model, 7-day lead time. Custom / non-standard: 100 sets, ~30 days. Mixed-size orders accepted.
