Datasheet - SYJ 40 KF

SKF SYJ Series Plummer Block House, 35mm Inside Diameter, 49.2mm Centre Height - SYJ 40 KF

This plummer Block housing provides bearing support for rotating shafts in industrial assemblies, offering a cast-iron enclosure with a tapered-bore mounting option and an adaptor-sleeve locking system. It is designed for applications requiring a Compact centre height and reliable load transmission while complying with relevant manufacturing standards.

Features and Benefits:

• 4800 r/min limiting speed enables moderately high-speed operation
• 30.7 kN dynamic load rating supports substantial radial loads
• 19 kN static load rating resists heavy stationary forces
• adaptor-sleeve locking ensures precise shaft clamping
• Cast-iron construction offers structural rigidity and vibration damping

Applications

• Suitable for conveyor drive shafts in automation lines
• Ideal for motor-driven assemblies in electrical equipment
• Used with gearboxes in mechanical power transmission systems
• Can be used for rotating components in electronics manufacturing

What bore configuration does this housing use for shaft attachment?

The internal bore is tapered to accept an adaptor sleeve, allowing controlled interference fit and axial positioning without separate locking collars.

What mounting provisions are available for installation?

The unit mounts with two bolts through 14mm holes spaced at 136.5mm centre-to-centre, facilitating secure base attachment.

Which shaft size is compatible with the tapered bore?

The housing accommodates shafts with an effective inside diameter of 35mm when the adaptor sleeve is fitted.

How does the housing height influence alignment tasks?

The centre height of 49.2mm helps determine bearing-line alignment relative to neighbouring components for accurate shaft coupling.

What are the overall envelope dimensions affecting layout?

The cast-iron housing measures 184mm in length and 99mm in external height, information useful for spatial planning and clearance calculations.
