1. What are the main differences between the 6836 Bearing and the 6840 Bearing?

The primary differences between the two bearings stem from their dimensions and load capacities. Here are the specifics:

1. Dimensions:
   • The 6836 Bearing typically has an inner diameter of 180 mm, an outer diameter of 225 mm, and a width of 22 mm.
   • The 6840 Bearing features an inner diameter of 200 mm, an outer diameter of 250 mm, and a width of 30 mm.
2. Load Capacity:
   • The 6836 Bearing is ideal for applications requiring moderate load capacities and speeds.
   • The 6840 Bearing is designed for heavier loads and higher speeds due to its larger size.
3. Weight:
   • The 6836 Bearing weighs less, making it suitable for applications where weight is a concern.
   • The 6840 Bearing, although heavier, can handle more demanding requirements.

2. What applications are best suited for each bearing?

Both the 6836 Bearing and the 6840 Bearing have their unique applications based on their specifications:

1. 6836 Bearing:
   • Commonly used in electric motors, robotics, and light machinery where moderate load capacity is needed.
   • Due to its lightweight design, it is preferred in applications where minimizing weight is key.
2. 6840 Bearing:
   • Suitable for heavy-duty applications, such as industrial equipment, conveyors, and automotive sectors.
   • Its higher load capacity makes it ideal for scenarios where durability and strength are essential.

3. How do I decide which bearing to choose?

Choosing between the 6836 Bearing and the 6840 Bearing depends on several factors:

1. Load Requirements:
   • If your application requires lower loads and speed, the 6836 Bearing would be the correct choice.
   • For applications that involve heavier loads or higher speeds, opt for the 6840 Bearing.
2. Space Constraints:
   • The 6836 Bearing may be better for tighter spaces due to its smaller dimensions.
   • The 6840 Bearing will need more room because of its larger size, which may be a concern in compact areas.
3. Budget:
   • The 6836 Bearing is typically more economical, making it ideal for budget-conscious projects.
   • While the 6840 Bearing may be more expensive, its durability can result in cost savings in heavy-use applications over time.

4. Conclusion

In summary, both the 6836 Bearing and the 6840 Bearing serve important roles in various industries. If you need a lightweight option for moderate applications, the 6836 Bearing is your best bet. However, for higher load capacities and industrial uses, the 6840 Bearing provides the strength and durability necessary. Assessing your specific needs will guide you to the right choice between these two effective options.
