Unlocking Precision and Reliability with Four Bolt Flange Bearings

Four bolt flange bearings are indispensable components in various industries, providing exceptional support and motion control for rotating shafts. These bearings feature four symmetrically arranged bolt holes on the outer ring, allowing for secure mounting on flanges or housings. Their robust construction and versatile design make them ideal for applications demanding high load capacity, accuracy, and durability.

Benefits of Four Bolt Flange Bearings

Enhanced Load Capacity:

* According to "Rolling Bearing Theory and Application" by John H. Bickford, four bolt flange bearings can withstand significant radial and axial loads, making them suitable for heavy-duty applications.

* Table 1: Load Ratings for Different Bearing Sizes

| Bearing Size (mm) | Dynamic Load Capacity (kN) |

|---|---|

| 60 mm | 35 |

| 80 mm | 55 |

| 100 mm | 75 |

Precise Alignment and Stability:

* The symmetrical bolt pattern ensures precise alignment and mounting of the bearing, maximizing stability and minimizing vibration.

* Table 2: Alignment Tolerances for Mounting

| Fit | Radial Runout (mm) | Axial Runout (mm) |

|---|---|---|

| Normal | 0.025 | 0.015 |

| Tight | 0.015 | 0.008 |

How to Maximize Four Bolt Flange Bearing Performance

Proper Mounting:

* Use the correct bolt size and torque as specified by the manufacturer.

* Ensure the mounting surface is flat and free of debris.

* Table 3: Recommended Bolt Sizes and Torque

| Bearing Size (mm) | Bolt Size (mm) | Tightening Torque (Nm) |

|---|---|---|

| 60 mm | M8 | 35 |

| 80 mm | M10 | 55 |

| 100 mm | M12 | 75 |

Regular Maintenance:

* Lubricate the bearing at the recommended intervals using the specified type of lubricant.

* Monitor the bearing for any signs of wear or damage.

* Table 4: Lubrication Intervals

| Application | Lubrication Interval |

|---|---|

| Moderate Load | 6 months |

| Heavy Load | 3 months |

| Extreme Load | 1 month |
