Self-Aligning Ball Bearings – Reliable Alignment for Every Application

Here at Bolton Engineering Products Ltd we are a leading UK self-aligning ball bearing stockist, supplying the most comprehensive range of very high-quality bearings for use in difficult working environments.

Our self-aligning ball bearings are designed for use in applications where shaft deflection or misalignment may occur, such as printing and packaging machinery, industrial fans and agricultural equipment.

What Are Self-Aligning Ball Bearings?

Self-aligning ball bearings have two rows of steel balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. This innovative design is the ideal answer to align and support your bearings in heavy loads or misalignment, without increasing friction, wear, or stress.

Common Applications:

Agricultural and construction machinery
Conveyor systems and textile equipment
HVAC fans and blowers
Electric motors and pumps
Printing, packaging, and general industrial use

FAQs

Q1：What is a characteristic of self-aligning ball bearings compared to general bearings?

The outer ring raceway is in spherical shape so that it is self-aligning and will balance minor misalignments of the shaft.

Q2: How will they tolerate with misalignments?

Usually no more than 3 degrees, depending on the bearing size and design.

Q3: Are self-aligning bearings regular greased or need to be re-lubricated?

No. Lubricated and no maintenance is necessary other than preventing dust or foreign matter from being drawn in.

Q4: Are sealed options available?

Absolutely, there are open, shielded and sealed options to cater to different environments and conditions.
