Product Advantages

Optimized Axial Load Performance
Engineered with precise internal contact geometry to distribute heavy axial stresses evenly across all rolling elements. Guarantees stable and reliable operation under extreme, demanding industrial thrust force conditions.

Precision Machining & Long Service Life
Manufactured using high-purity GCr15 bearing steel subjected to advanced thermal control for superior hardness. Achieves exceptional wear resistance, microstructural stability, and extended fatigue life under continuous operation.

Separable Design for Easy Installation
Features independent shaft washers, housing washers, and cage assemblies that can be mounted separately. Significantly simplifies initial machinery assembly, routine field inspections, and replacement procedures.

Comprehensive Customization & Versatility
Available in extensive standard metric sizes as well as high-precision grades ranging from normal class up to P4. Offers flexible cage material options including stamped steel and machined brass to match specific speed demands.

Product Types

Single Direction Thrust Ball Bearings

Designed with a shaft washer, a housing washer, and a ball-and-cage assembly to support and transmit axial loads strictly in one direction. Features a compact, separable structure that ensures reliable vertical shaft positioning and simplified component installation.

Double Direction Thrust Ball Bearings

Built with a central shaft washer and two housing washers with separate ball assemblies to support bidirectional loads. Provides reliable axial support and enhanced positioning accuracy for applications operating under frequent reversing forces.

Self-Aligning Thrust Ball Bearings

Incorporates a spherical housing washer paired with an aligning seat washer to actively absorb angular errors. Effectively compensates for minor mounting misalignments and shaft deflections during operational cycles.

Cranes, hoists, and high-thrust rotary joints.

OEM & Custom Engineering

Custom Dimensions

Non-standard sizes and specialized cage configurations built to blueprints.

Private Labeling

Industrial export packaging and OEM branding support.

Scalable Production

High-volume manufacturing capacity for global distributors.

FAQ

Q: Can thrust ball bearings handle radial loads?

A: No. They are exclusively optimized for axial loads and should not be subjected to significant radial forces.

Q: Are these bearings rated for high-speed operation?

A: Yes. Precision grades (P5/P4) support moderate to high speeds when paired with proper lubrication.

Q: Does ZWZ accept custom drawings?

A: Yes. Our engineering team directly supports OEM customization based on client specifications or samples.

Q: What is the standard material used for ZWZ thrust bearing cages?

A: Standard cages are manufactured from pressed steel for general applications, while machined brass cages are used for heavy-duty, high-load, or high-speed industrial environments.

Q: How should I properly lubricate thrust ball bearings?

A: Depending on the operational speed and load, either high-performance lithium-base grease or circulating oil lubrication is recommended to minimize friction and prevent premature wear.
