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.

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.
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?
标准系列 sizes: 1000 sets/model, 7-day lead time. Custom / non-standard: 100 sets, ~30 days. Mixed-size orders accepted.
标准系列 codes or drawings — we quote volume pricing and lead time.
