Inner Ball Mounted Pillow Block

Specifications

1. Housing:

• Material: Typically cast iron, steel, or aluminum alloy, depending on the model.
• Mounting Style: Can be oval or square flange.
• Mounting Holes: 2 or 4 holes, depending on the size and shape of the block.
• Self-Aligning: Some models are self-aligning to accommodate shaft misalignment.

2. Ball Bearing:

• Material: Usually made from bearing steel (chrome steel), stainless steel for corrosion resistance, or ceramic for specific applications.
• Inner Diameter (Bore Size): Common sizes range from 8 mm to 50 mm or more depending on the specific model and application.
• Outer Diameter: Varies with the housing.
• Type: Usually a deep groove ball bearing.
• Seals: Can be opened, sealed (2RS), or shielded (ZZ) to protect against dust and moisture.

3. Key Performance Metrics:

• Dynamic Load Rating: Depends on the size but typically ranges from 5 kN to 20 kN for most models.
• Static Load Rating: Typically ranges from 2.5 kN to 12 kN, depending on the size and material.
• Speed Rating: Up to 3000 RPM or more, depending on the bearing design and lubrication.

4. Features:

• Self-aligning: Many models have a self-aligning feature to compensate for slight misalignment between the shaft and housing.
• Lubrication: Grease lubrication is common, with a re-lubrication feature through a grease nipple.
• Vibration Resistance: The inner ball is securely mounted to reduce vibration and noise in the operation.

5. Dimensions (Example):

• Length: Ranges from 65 mm to over 150 mm.
• Height: Varies based on the model but usually between 30 mm and 90 mm.
• Mounting Hole Diameter: Around 6 mm to 12 mm depending on the block size.

Applications:

• Conveyor systems
• Agricultural equipment
• Light and heavy machinery
• HVAC systems
• Automotive applications
