Angular Contact Ball Bearing QJZ 5205-2RS 25mm x 52mm x 20.6mm 2RS

Description

Product Overview

The QJZ 5205-2RS angular contact ball bearing is engineered for high‑performance applications where precision, durability, and protection from contaminants are essential. Constructed from high‑grade steel, the bearing delivers exceptional load‑carrying capacity while maintaining tight tolerances for smooth rotation. The double rubber seal (2RS) provides a robust barrier against moisture, dust, and other harsh environmental elements, ensuring long‑term reliability even in the most demanding industrial settings.

Measuring 25 mm in inner diameter, 52 mm in outer diameter, and 20.6 mm in width, this bearing conforms to the standard 5205 size series, making it a direct replacement for a wide range of legacy components. Its angular contact design allows it to accommodate both radial and axial loads, delivering superior performance in high‑speed applications such as gearboxes, motor shafts, and precision equipment. The bearing’s geometry ensures optimal load distribution, reducing wear and extending service intervals.

Usage

Designed for versatility, the 5205-2RS bearing excels in automotive systems, agricultural machinery, construction equipment, and a broad spectrum of industrial machinery. Whether installed in a tractor’s power take‑off, a CNC machine spindle, or a heavy‑duty pump, the bearing’s sealed construction protects internal components from oil, water, and particulate ingress. This makes it especially suitable for outdoor equipment that operates in dusty, wet, or temperature‑extreme environments.

Engineers and maintenance professionals appreciate the bearing’s ease of installation. The standard bore size aligns with common shaft dimensions, and the double seal eliminates the need for additional protective housings. This reduces assembly time and simplifies inventory management, as the 5205-2RS can serve as a universal solution across multiple equipment lines.

FAQ

What does the 2RS designation mean?

2RS indicates that the bearing has two rubber seals—one on each side of the bearing race. These seals prevent ingress of dust, water, and other contaminants, protecting the internal rolling elements and extending service life.

Can this bearing be used in high‑speed applications?

Yes. The angular contact geometry and high‑grade steel material allow the 5205‑2RS bearing to operate at high rotational speeds while maintaining stability and low vibration, making it suitable for motor shafts, gearboxes, and spindle applications.

Is the bearing compatible with standard 5205 shafts?

Absolutely. The bearing’s 25 mm inner diameter matches the standard 5205 shaft size, ensuring a direct fit without the need for adapters or modifications.

How does the double seal improve performance compared to open bearings?

The double seal creates a sealed environment that keeps lubricants inside and contaminants out. This reduces the frequency of re‑lubrication, minimizes wear, and helps maintain consistent performance over longer intervals.

What warranty or support is offered?

We provide a limited warranty covering manufacturing defects and offer technical assistance for installation, maintenance, and troubleshooting. Our customer service team is available to help you maximize the bearing’s performance in your specific application.
