6901 C3 Deep Groove Bearing Chrome Steel Ruber Bearing for Industrial Wheels Pump Gear Equipment

Material - Rolling Balls are made of chrome steel with excellent surface quality, high hardness, high load capacity, and wear resistance. Cage & Inner Outer Race are both made of stamping steel.
Features - Single row, double sealed type. We can do ABEC-5 accuracy, Z3 noise level. They are used to accommodate radial and axial loads in both directions.
Applications - Suitable for many kinds of industrial equipment, such as pumps, motors, gearboxes, conveyors, and power tools.
Notice - These bearings often feature a simple design, allowing for easy disassembly, lubrication, and maintenance, which contributes to their longevity and overall performance.

1. Higher Hardness and Wear Resistance
Chrome steel contains chromium, which significantly increases the hardness of the material (typically 60-64 HRC). This makes the bearings highly resistant to wear and abrasion, even under heavy loads or high-speed conditions.
2. Superior Fatigue Resistance
The high chromium content improves the fatigue strength of the material, allowing chrome steel bearings to withstand repeated stress cycles without failure. This makes them ideal for applications with dynamic or cyclic loading.
3. Enhanced Corrosion Resistance
While not as corrosion-resistant as stainless steel, chrome steel bearings offer better resistance to rust and corrosion compared to standard carbon steel bearings. This is due to the chromium content, which forms a passive oxide layer on the surface.
4. Higher Load Capacity
The high hardness and strength of chrome steel allow these bearings to handle higher radial and axial loads compared to standard bearings. This makes them suitable for heavy-duty applications.
5. Better Dimensional Stability
Chrome steel has excellent dimensional stability, meaning it maintains its shape and size under varying temperatures and loads. This ensures consistent performance and longer service life.
6. Improved Heat Resistance
Chrome steel can withstand higher operating temperatures compared to standard carbon steel bearings. This makes them suitable for applications where heat generation is a concern, such as in high-speed machinery.
7. Smoother Surface Finish
Chrome steel bearings are manufactured with a smoother surface finish, which reduces friction and improves efficiency. This also contributes to quieter operation and reduced heat generation.
8. Longer Service Life
Due to their superior hardness, wear resistance, and fatigue strength, chrome steel bearings generally have a longer service life compared to standard bearings. This reduces the need for frequent replacements and lowers maintenance costs.
9. Cost-Effectiveness in the Long Run
While chrome steel bearings may have a higher initial cost, their durability and performance make them more cost-effective in the long run due to reduced downtime and maintenance.
