5211-2RS 55x100x33.3 mm Double Row Angular Contact Bearings 5211

Description

Product Overview

The WOWCLEDED 5211-2RS is a precision‑engineered double row angular contact bearing designed for demanding power transmission environments. Measuring 55 mm in inner diameter, 100 mm in outer diameter, and 33.3 mm in width, this bearing provides a compact yet robust solution for a wide range of industrial applications. Constructed from high‑grade alloy steel, the bearing offers exceptional hardness, wear resistance, and fatigue strength, ensuring reliable operation under heavy radial and axial loads.

Its angular contact geometry allows for precise shaft alignment, reducing deflection and improving overall system efficiency. The double row configuration not only doubles the load‑carrying capacity compared to single row designs but also enhances stiffness, which is critical for high‑speed machinery where vibration control is paramount. The bearing is supplied pre‑lubricated with a high‑performance grease that extends service life and minimizes maintenance intervals.

Key specifications include a package dimension of 1.18 × 0.79 × 0.39 inches and a weight of 1.21 lb, making it easy to handle and install. The product is listed under the ASIN B0F21TWBVW and ranks #69 in the Angular Contact Bearings category on major e‑commerce platforms, reflecting its popularity among engineers and procurement specialists.

Usage

This bearing excels in applications that demand high radial and axial load handling, such as gearboxes, motor shafts, pumps, and high‑speed spindles. Its compact size and robust construction make it suitable for both new equipment designs and retrofitting projects where space constraints are a concern. In heavy‑duty industrial settings, the 5211-2RS provides the stability required for continuous operation, reducing downtime caused by bearing wear or misalignment.

Engineers often select this bearing for precision equipment that operates at speeds up to 10,000 rpm, thanks to its ability to maintain tight tolerances and resist thermal expansion. The double row design also offers redundancy; if one row experiences localized wear, the second row continues to support the load, extending the overall service life of the assembly. This makes the 5211-2RS an excellent choice for critical machinery in manufacturing, aerospace, and energy sectors.

Installation is straightforward—no additional assembly is required, and the bearing can be mounted directly onto shafts or housings using standard mounting methods. Its pre‑lubricated state eliminates the need for immediate greasing, allowing technicians to focus on other aspects of system integration. The bearing’s durability and performance have been validated through rigorous testing, ensuring compliance with industry standards for angular contact bearings.

FAQ

What load capacities can the 5211-2RS handle?

The bearing is rated for high radial loads up to 5,000 N and axial loads up to 2,500 N, making it suitable for heavy‑duty industrial machinery that experiences combined loading conditions.

Is the bearing suitable for high‑speed operation?

Yes, the 5211-2RS is designed for speeds up to 10,000 rpm. Its angular contact geometry and double row configuration maintain tight tolerances and minimize deflection at high rotational velocities.

Can the bearing be used in environments with extreme temperatures?

The bearing’s alloy steel material and high‑performance grease allow operation in temperature ranges from –30 °C to +120 °C. For applications beyond this range, a specialized lubricant can be selected.

What maintenance is required for this bearing?

Because the bearing is pre‑lubricated, routine maintenance is minimal. Periodic inspection for signs of wear, contamination, or misalignment is recommended. If the bearing operates in harsh conditions, re‑greasing at scheduled intervals can further extend its lifespan.

How do I ensure proper installation?

Follow the manufacturer’s mounting guidelines: clean the shaft and housing surfaces, apply a thin layer of compatible grease if additional lubrication is needed, and use appropriate tools to avoid excessive force that could damage the bearing races.
