Wide Section Ball Bearings

**TIMKEN Deep Groove and Wide Inner Ring Ball Bearings: Precision, Durability & Performance for Demanding Applications**

TIMKEN® ball bearings, including deep groove ball bearings (62000, 63000 series) and wide inner ring (WIB) designs, represent industry-leading solutions for applications requiring high-speed operation, radial load capacity, and long service life. Engineered with precision materials and advanced manufacturing techniques, these bearings excel in industrial machinery, automotive systems, and precision equipment where reliability and efficiency are critical.

### **Technical Features & Design Advantages**
TIMKEN deep groove ball bearings feature a robust single-row design with uninterrupted raceways, enabling them to handle both radial and moderate axial (thrust) loads. The 62000 and 63000 series are distinguished by their bore size, outer diameter, and width dimensions, with the 63000 series offering higher load capacity due to its larger cross-section. Key design elements include:

– **High-Grade Steel Construction:** Manufactured from premium chromium steel (SAE 52100 or equivalent), these bearings provide exceptional hardness, wear resistance, and fatigue life.
– **Precision-Ground Raceways:** Optimized contact geometry minimizes friction and heat generation, enhancing efficiency in high-speed applications.
– **Versatile Sealing & Shielding Options:** Bearings are available with rubber seals (RS, 2RS) or metal shields (ZZ) to protect against contamination while retaining lubrication.
– **Wide Inner Ring (WIB) Variants:** Designed for simplified mounting in pulley, sprocket, or gear applications, WIB bearings eliminate the need for additional adapters, reducing assembly complexity.

### **Performance Benefits**
TIMKEN deep groove and WIB ball bearings deliver superior performance in demanding environments:

– **High-Speed Capability:** Low friction and balanced internal clearance allow for smooth operation at elevated RPMs, making them ideal for electric motors, pumps, and fans.
– **Extended Service Life:** Advanced heat treatment and surface finishing techniques reduce micropitting and spalling, ensuring durability even under continuous loads.
– **Reduced Maintenance Needs:** High-quality grease lubrication and effective sealing minimize relubrication intervals, lowering total cost of ownership.

### **Typical Applications**
These bearings are widely used across industries, including:

– **Industrial Machinery:** Electric motors, gearboxes, conveyors, and material handling equipment.
– **Automotive Systems:** Alternators, water pumps, transmission components, and wheel hubs (supplemental applications).
– **Precision Equipment:** Medical devices, robotics, and small appliance drives where quiet operation is essential.

With a legacy of innovation, TIMKEN deep groove and WIB ball bearings combine precision engineering with rugged reliability, making them a trusted choice for engineers seeking optimal performance in rotating machinery. Whether in high-load industrial settings or high-speed automotive applications, these bearings ensure smooth operation, reduced downtime, and extended equipment life.
