FAG – 4201-2RS – Deep Groove Ball Bearing – Double Row

The FAG 4201-2RS is a high-performance double row deep groove ball bearing designed to deliver exceptional load-carrying capacity, smooth rotation, and long service life. Manufactured by FAG, a globally recognized leader in bearing technology and a part of the Schaeffler Group, this bearing is engineered for reliability in demanding industrial and mechanical applications. Its compact size, sealed construction, and durable design make it an ideal choice for users seeking consistent performance in confined or high-speed environments.

This particular model, the FAG 4201-2RS, features double rows of precision steel balls that offer greater radial load handling than single-row bearings. The double row design enhances stability and allows the bearing to manage both radial and limited axial loads in either direction. This makes it suitable for applications that involve variable loads, such as electric motors, conveyors, fans, gearboxes, agricultural machinery, and precision instruments.

One of the key features of the 4201-2RS is its rubber seals on both sides (denoted by the “2RS” suffix). These synthetic rubber seals are securely fixed into a groove in the outer ring, providing effective protection against dust, dirt, and moisture while retaining the bearing’s internal lubrication. The result is a maintenance-free design that offers improved reliability and reduced downtime in dusty or contaminated environments. The seals also help prevent lubricant leakage, maintaining consistent performance over time.

The dimensions of this bearing are:

• Inner Diameter (ID): 12 mm

• Outer Diameter (OD): 32 mm

• Width (Thickness): 14 mm

These dimensions make the FAG 4201-2RS particularly well-suited for compact designs or installations where space is limited. Despite its small footprint, the bearing provides impressive performance characteristics due to its robust internal construction and high-quality materials.

The deep groove raceways are precisely machined to allow the steel balls to rotate smoothly with minimal friction. This low-friction operation translates to reduced energy loss, lower operating temperatures, and increased bearing lifespan. In high-speed environments, this efficiency also contributes to quieter operation and less mechanical vibration, making the 4201-2RS suitable for noise-sensitive applications like medical devices or office machinery.

FAG uses premium-grade bearing steel that is heat-treated for superior hardness, wear resistance, and fatigue strength. This ensures that the 4201-2RS can withstand demanding workloads and extreme conditions while maintaining dimensional stability. The robust construction also makes it suitable for continuous-duty applications where reliability is essential.

Installation of the FAG 4201-2RS is straightforward, thanks to its standardized dimensions and compatibility with ISO and DIN standards. This means it can easily replace existing bearings of similar specifications without requiring custom modifications or adaptors. The bearing can be mounted using standard tools and procedures, making it accessible for both professional technicians and DIY users.

In terms of maintenance, the sealed design eliminates the need for frequent re-lubrication, offering a truly low-maintenance solution. This is especially important in hard-to-reach or sealed systems where disassembly is time-consuming or costly.

Whether used in high-speed electric motors, compact machinery, or industrial transmission systems, the FAG 4201-2RS bearing provides a perfect balance of durability, efficiency, and ease of use. Its double row design ensures greater rigidity and load-carrying capability compared to single-row alternatives, while the sealed construction enhances its service life and reliability in contaminated environments.

In summary, the FAG 4201-2RS Deep Groove Ball Bearing is a premium-quality, double-row bearing designed for high-performance mechanical applications. Its compact dimensions (12×32×14 mm), rubber seals for contaminant protection, and superior FAG engineering make it a dependable choice for a wide range of industries. Whether you’re building new equipment or replacing an existing bearing, the 4201-2RS delivers outstanding value through long-lasting performance, reduced maintenance, and smooth, quiet operation.
