SKF 6310-2Z/C3 Deep Groove Ball Bearing

Description

The SKF 6310-2Z/C3 is a single-row deep groove ball bearing, a versatile and widely used type of rolling bearing. This model features two metal shields (2Z) to protect against the ingress of dirt and solid contaminants. The C3 internal clearance is greater than standard, making it suitable for applications with high speeds or significant temperature differences between the rings. It is designed to accommodate both radial and axial loads in both directions.

FAQ

The 'C3' designation indicates that the bearing has a radial internal clearance that is greater than the 'Normal' (CN) standard. This is essential for applications involving high speeds, temperature variations, or interference fits, as it allows for thermal expansion without causing excessive preload.

While the '2Z' steel shields offer good protection against solid contaminants like dust and dirt, they are non-contacting and do not provide a perfect seal against moisture ingress. For applications with high humidity or direct water exposure, a bearing with rubber seals (e.g., SKF 6310-2RS1) would be a more suitable choice.

The limiting speed for the SKF 6310-2Z/C3 is typically around 6300 revolutions per minute (r/min) for grease lubrication. However, this value can be influenced by factors such as the specific lubricant used, operating temperature, and load conditions. Always consult the official SKF technical datasheet for precise calculations based on your application.
