Deep groove ball bearings are the most widely used type of rolling bearing; The characteristics of deep groove ball bearings include low friction resistance and high rotational speed. They can be used in components that endure radial loads, or combined radial and axial loads simultaneously, as well as in components that endure axial loads, Deep groove ball bearings are often used in industries such as steel and metallurgy, energy and power generation, railways and high-speed rail, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, and engineering machinery; Common types of deep groove ball bearings include single row deep groove ball bearings, miniature and small ball bearings, full complement deep groove ball bearings, and magnetoelectric machine ball bearings.

The designs of ZNY's various angular contact ball bearings can meet these diverse requirements. Angular contact ball bearings have a contact angle and, therefore, can simultaneously bear radial loads and large axial loads in one direction. Additionally, when angular contact ball bearings carry radial loads, since these loads have an axial component, they are generally used in combination, such as in sets of 2, 3, or 4 bearings.

Tapered Roller Bearings: The design features the inner and outer ring raceway surfaces and the cone apexes of the rollers converging at a single point on the bearing's central axis. The truncated cone-shaped rollers, serving as the rolling elements, are assembled in the bearing, guided by the large edge of the inner ring. They can withstand radial loads and unidirectional axial loads. When a load is applied, it generates an axial component of force, so like angular contact ball bearings, they are typically used in pairs or must be used in a double-row bearing configuration. In this case, the appropriate internal clearance can be set by adjusting the space between the inner and outer rings. As they are separable, the inner and outer rings can be disassembled separately. For high-load capacity, there's the HR series with increased roller size and number. Depending on the contact angle size, they are classified into normal, medium, and large cone angle bearings. Based on the number of roller rows, they can be divided into double-row and four-row tapered roller bearings. Generally, steel plate stamped cages are used, but large-size tapered roller bearings also use pin-type cages.

ZNY's thrust ball bearings are designed to withstand thrust loads during high-speed operation, consisting of washer-like raceways with ball rolling. As the raceways are seat-shaped, thrust ball bearings are divided into two types: flat seat type and self-aligning spherical seat type. Additionally, these bearings can bear axial loads but cannot withstand radial loads. ZNY's thrust ball bearings come in two types: single-direction and double-direction. The single-direction thrust ball bearings consist of two race rings (shaft ring and bearing seat ring) and one cage with balls. Double-direction thrust ball bearings are composed of three race rings and two cages with balls. For double-direction types, the design involves two ball-equipped cages clamping the shaft ring. Features Available in both single-direction and double-direction types. To accommodate installation errors, both single and double-direction types can choose either the spherical self-aligning seat type or the type with a spherical seat ring.
