Description
NTN HTA922UDB belongs to thrust ball bearing de contacto angular, part of our Bearings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for HTA922UDB and any equivalents.
The NTN HTA series thrust ball bearing is an angular contact bearing built to handle axial loads in a single direction, with high precision and high-speed capability. It suits machine tool spindles, rotary tables and precision equipment where axial rigidity and clearance control matter.
The part number tells you a lot. HTA identifies NTN's angular contact thrust ball bearing family, and the number after it indicates the size within the series. A UDB suffix means a matched pair with a defined preload, supplied ready to mount as a set. Other suffixes can point to preload or design variants, so it is worth confirming the complete reference when you request a quote.
Typical applications include milling, grinding and machining center spindles, where the bearing takes the axial thrust without giving up precision. You will also find them in coordinate tables, deep-hole drilling heads and measuring equipment.
Selection depends on three things: axial load, rotation speed and the rigidity you need. Installation calls for clean conditions, correct alignment and proper preload, because too much or too little tightening affects service life. Choose grease or oil based on the operating regime, and use sealing to keep contaminants out. In UDB pairs, the axial clearance is already set by the manufacturer.
When you need an equivalent, keep in mind that each maker uses its own naming for angular contact thrust bearings. If you have a part number from another brand, send it with the main dimensions — bore, outer diameter and height — so the equivalent NTN reference can be identified. Not every series is dimensionally interchangeable, so a technical check before replacement is essential.

Frequently asked questions
- What does the UDB suffix mean on an HTA bearing?
- UDB indicates a pair of angular contact thrust bearings matched with a preload defined by the manufacturer. They mount as a set to take axial loads in one direction, with rigidity and clearance already established.
- How do I request a quote for an HTA bearing?
- Send the full part number, for example HTA010UDB, by WhatsApp or email. If you are unsure of the part number, include the main dimensions and a photo of the part so it can be identified.
- Can I replace an HTA bearing with one from another brand?
- Yes, provided dimensions and load capacity match. Each manufacturer uses its own nomenclature, so send the original brand's part number and dimensions so the equivalent NTN reference can be confirmed and interchangeability verified.
