TIMKEN 592XS Tapered Roller Bearing Cup | Single Outer Race

What is the TIMKEN 592XS?

The TIMKEN 592XS is a premium single cup (outer race) for a single-row tapered roller bearing. It is designed to be paired with a compatible TIMKEN cone (inner ring with tapered rollers) to create a complete tapered roller bearing assembly.

Unlike a complete bearing, the 592XS is supplied as the outer ring only, allowing replacement of individual bearing components where appropriate. Manufactured to TIMKEN's OEM standards, it delivers outstanding precision, durability and reliability for demanding industrial applications.

Tapered Roller Bearing Design

A tapered roller bearing consists of two separate components:

• Cone – inner ring with tapered rollers and cage
• Cup – outer ring (bearing race)

This separable design simplifies installation, inspection and maintenance while allowing accurate bearing preload and adjustment.

Tapered roller bearings are engineered to support both radial and axial (thrust) loads simultaneously, making them ideal for demanding mechanical systems.

Always verify compatibility using the complete bearing designation and manufacturer's catalog before installation.

FAQ

Is TIMKEN 592XS a complete bearing?

No. The 592XS is only the outer ring (cup) of a tapered roller bearing.

What are the dimensions?

• Outside diameter: 147.638 mm
• Cup width: 26.192 mm

What bearing type does it belong to?

It is a single-row tapered roller bearing cup.

Can the cup be replaced separately?

Yes. Tapered roller bearings have a separable design, allowing the cup and cone to be replaced individually when appropriate.

What loads can it support?

When assembled with the correct cone, the bearing supports high radial loads together with axial loads in one direction.

Frequently Asked Questions from Mechanics and Engineers

Why use tapered roller bearings?

Tapered roller bearings simultaneously support radial and thrust loads while providing excellent stiffness, making them ideal for gearboxes, wheel hubs and heavy industrial machinery.

Why replace only the cup?

If inspection confirms that only the outer race is worn or damaged, replacing the cup may restore proper bearing performance when paired with a compatible cone in suitable condition.

What are common causes of bearing failure?

• Incorrect preload
• Improper installation
• Contamination
• Inadequate lubrication
• Excessive operating temperatures
• Overloading
• Misalignment
• Water ingress
