Frequently Asked Questions - Product Advantages & Disadvantages

Pot Bearing Advantages:

• Pot Bearings are multi-rotational
• Pot Bearings have negligible vertical deflection under load.
• Pot Bearings have uniform vertical deflection under load.
• Pot Bearings have high vertical and horizontal load capacity.
• Pot Bearings cause relatively low stress on the bearing seats.

 
Pot Bearing Disadvantages:

• Pot Bearings require periodic maintenance.
• While pot bearings are relatively low in height, other bearing types – such as Disc Bearings – are usually lower in overall height.

Disc Bearing Advantages:

• Disc Bearings are multi-rotational.
• Disc Bearings have relatively high vertical load capacity and medium-high to medium horizontal load capacity.
• Disc Bearings require less maintenance than Pot Bearings.
• Disc Bearings are usually low in overall height.

 
Disc Bearing Disadvantages:

• Disc Bearings still require some periodic maintenance.
• Disc Bearings exhibit more vertical deflection than Pot Bearings.
• Disc Bearings exhibit varying degrees of vertical deflection from bearing to bearing.

Laminated Elastomeric Bearing Advantages:

• Laminated Elastomeric Bearings are the lowest initial cost bearing type.
• Laminated Elastomeric Bearings are very low maintenance if installed properly.
• Laminated Elastomeric Bearings may be combined with PTFE/Stainless Steel sliding surface components to accommodate larger movements.
• Many different configurations of laminated Elastomeric Bearings are possible.

 
Laminated Elastomeric Bearing Disadvantages:

• Laminated Elastomeric Bearings are not well suited for multi-rotation.
• Laminated Elastomeric Bearings can “walk” out of place with time if not positively held in place.
• Laminated Elastomeric Bearings exhibit more vertical deflection than Pot Bearings.
• Laminated Elastomeric Bearings exhibit varying degrees of vertical deflection from bearing to bearing.

Spherical Bearing Advantages:

• Spherical Bearings are multi-rotational.
• Spherical Bearings can accommodate higher rotations then most other multi-rotational bearings.
• Spherical Bearings have relatively high vertical load capacity and medium-high to medium horizontal load capacity.
• Spherical Bearings are usually low in overall height.
• Spherical Bearings have negligible vertical deflection under load.
• Spherical Bearings have uniform vertical deflection under load.

 
Spherical Bearing Disadvantages:

• Spherical Bearings require careful attention when installing – especially to insure no disassembly.
• Spherical Bearings require periodic maintenance.

Self-Lubricating Bronze Bearing Advantages:

• Self-Lubricating Bronze Bearings can be made multi-rotational.
• Self-Lubricating Bronze Bearings have negligible vertical deflection under load.
• Self-Lubricating Bronze Bearings have uniform vertical deflection under load.

 
Self-Lubricating Bronze Bearing Disadvantages:

• Self-Lubricating Bronze Bearings require periodic maintenance.
• All Sliding surfaces must be kept free of debris.
