Understanding the 6844-2RS Bearing

What is a 6844-2RS Bearing?

The 6844-2RS Bearing is a deep groove ball bearing that is designed with two rubber seals, providing protection against dust and moisture. It is particularly valued for its reliability and can be found in various applications ranging from automotive components to industrial machinery.

Key Specifications

• Inner Diameter: 220 mm
• Outer Diameter: 270 mm
• Width: 28 mm
• Material: High-quality steel
• Sealing Type: 2RS (rubber seals on both sides)

Factors to Consider

Load Rating

When selecting a 6844-2RS Bearing, it's essential to evaluate the load rating. This determines the amount of weight that the bearing can support without failing. Consider the following:

• Dynamic Load Rating: Suitable for applications where the load is constantly changing.
• Static Load Rating: More relevant for applications where the load remains constant.

Operating Conditions

Evaluate the conditions in which the bearing will operate. Factors such as temperature, humidity, and exposure to chemicals can affect performance. The 6844-2RS Bearing is designed to function effectively in various conditions, but adherence to the following guidelines can enhance longevity:

• Ensure proper lubrication to prevent overheating.
• Choose bearings with seals to protect against contaminants.

Speed Ratings

The capacity of the 6844-2RS Bearing to handle speed is another critical factor. Higher speeds require bearings with specific design attributes to minimize friction. Keep an eye on the maximum RPM specified by the manufacturer to avoid premature wear.
