Thrust Ball Bearing 51204 ZEN 20x40x14 mm

Technical Specifications & Key Features

The 51204 ZEN bearing is a single-direction thrust ball bearing with nominal dimensions d = 20 mm, D = 40 mm, B = 14 mm. It is engineered specifically to handle axial (thrust) loads in one direction, making it suitable for high-performance industrial applications. According to manufacturer data, this thrust version is designed for efficient axial support, offering high durability and reliable performance under demanding conditions. The bearing is constructed from high-grade chrome steel and suitable for integration in bearing assemblies or bearing housings.
Key features include:

• Precision 20 x 40 x 14 mm size—ensures compatibility with standard industrial setups and bearing housings.

• Thrust ball bearing design—optimized for axial load support, reducing friction and improving equipment lifespan.

• Industrial-grade construction—supports applications requiring high durability and minimal downtime.

Industrial Applications & Benefits

This thrust ball bearing 51204 ZEN is ideal for use in heavy-duty and high-precision setups: shaft assemblies, bearing units, bearing housings, mechanical presses, pumps, mixers and drive systems where axial load handling is critical. For B2B procurement and maintenance teams the benefits include:

• High durability: Designed for sustained axial loads and built to withstand demanding industrial environments.

• Easier integration as part of a bearing unit or within a bearing housing—allowing faster installation and reducing maintenance interruption.

• Standardized dimensions (20x40x14 mm) facilitate stock management, replacement cycles and quick servicing.

• Helps reduce total cost of ownership by minimizing downtime, lowering maintenance effort and ensuring stable operation.

FAQ

Q1: What load direction is the 51204 thrust ball bearing designed for?
A1: It is designed for axial loads in a single direction—ideal for applications where the bearing is mounted against a shaft face or housing and supports thrust rather than radial loads.

Q2: Can this bearing be used inside a bearing housing or unit?
A2: Yes. Due to its standard size and design, it can be mounted in a bearing housing or incorporated within a bearing unit, offering flexibility for industrial assemblies and B2B use.

Q3: Why choose a thrust ball bearing over a standard deep-groove ball bearing?
A3: When the primary load is axial (in the direction of the shaft), a thrust ball bearing like this one is optimized to handle those forces more effectively than a typical radial bearing, offering increased longevity and stability in that application.

Q4: Are the dimensions 20x40x14 mm common and easily accessible?
A4: Yes. This size is widely available and standardized in the bearing industry, making sourcing, stocking and replacement straightforward for industrial clients.

Q5: How quickly can B2B orders be dispatched for this bearing?
A5: This bearing is readily available for B2B clients with fast shipping options, supporting rapid procurement and minimizing downtime in maintenance cycles.
