Welcome to US HG

As a professional research firm and experienced manufacturer, we can also carry special research projects in bearing or OEM production either bearing or its components. Please don’t hesitate to contact us at [email protected] if you have special demands.

Thin-Section Bearings

The thin section bearings we produce consist of seven series of open types and five series of sealed types.

Precision Angular Contact Ball Bearing

HGT is a leading high precision angular contact ball bearing manufacturer and supplier from china.

Crossed Cylindrical Roller Bearings

Crossed cylindrical roller bearing is one kind of bearing whose rollers are square crossing arranged between outer ring and inner ring.

Spindle Bearings

The Spindle bearings produced by HGT can be divided into 4 series: 618 series、619 series、718 series、719 series.

Tapered Roller Bearings

The taper roller bearing is a separable type bearing which inner components (consists of rollers, cage, and inner ring) can be separated from outer ring.

Cylindrical Roller Bearings

cylindrical roller bearings are available in a variety of designs, series and sizes.


US HG Technology Corporation, located in Boston, is a professional supplier of standard, non-standard and customized bearings, especially the thin-section bearings and the customized bearing. With more than 18 years’ experience, we are able to design and manufacture various types of bearings with inner diameter ranging from 30mm to 6,000mm, either standard or nonstandard bearings, and the precision of our products can reach class 4 or higher. So far, our products are widely used in the fields of aerospace, medical equipment, robotics, metallurgy, mine, petroleum, machinery, wind energy, etc. Our current delivery date is 45 to 60 day after the order is placed.


Quality assurance is our promise. Company owns processing facilities with the international certifications; we regularly test our bearings for conformity and quality on all critical factors. We accept the globally accepted third parties such as SGS, ASIA, and etc. in order to insure our bearing qualities based on customer requirements. Additionally, our manufacturer is ISO 9001:2008 certified.


Single-row Four-point Contact Ball Slewing Bearing Type HS

The Single-row Four-point Contact Ball Slewing Bearing Type HS consists of two seating rings. It is characterized by compact structure, light weight and four-point contact between the steel balls and the arc raceway. It can bear axial force, radial force and overturning moment simultaneously. It is applicable to the engineering machinery, such as slewing conveyors, welding manipulators, small-and-medium cranes, and excavators.

Series :HS Series Without Gear, HS Series Internal Gear, HSW series Without Gear



Double-row angular contact ball bearings

The design of double row angular contact ball bearing is almost totally same as that of the single row angular contact ball bearing.owever, its axial dimension is relatively small.

Innner Diameter: 100-340mm

Outer Diamater: 180-520mm


Four-row cylindrical roller bearings

Four row cylindrical roller bearings are the one of the main bearings for rolling mills. They are compact structures and high stiffness, and can carry high radial loads but not axial load. Because of inner rings with no rids, inner and outer ring subassembly ( with full set of rollers and cage) can be mounted respectively.



Spherical roller bearings

Spherical roller bearings, whose inner ringss have two raceways, and outer race-ways are spherical. The centers of curvature of outer raceways are alse the bearing centers.

Innner Diameter: 150-1060mm

Outer Diamater: 225-1400mm


Spherical roller thrust bearings

Structural characteristics: Strong axial loading capacity, self-aligning, the concentricity and shaft deflection have small impacts to the bearing.Different structures have different allowable self-aligning angles.

Innner Diameter: 150-1250mm

Outer Diamater: 215-1800mm

With sincere appreciation for your friendship and goodwill, the team at US HG TECH CORP wishes you a very happy Holiday Season and a New Year filled with peace and prosperity. Thanks for your support in the past years. We value our relationship with you and look forward to working with you in the year to come.
