22222 KEJW33 TIMKEN 110x200x53 mm Spherical Roller Bearing

22222 KEJW33 TIMKEN 110x200x53 mm Spherical Roller Bearing

TIMKEN 22222 KEJW33 110x200x53 mm is a double row spherical roller bearing with a tapered bore, designed for applications involving high radial loads, combined loads and shaft-to-housing misalignment. The bearing has a 110 mm bore diameter, 200 mm outside diameter and 53 mm width. The EJ design uses a steel cage, while W33 identifies a lubrication feature in the outer ring.

Technical data - TIMKEN 22222 KEJW33

The dimensions, load ratings and thermal reference speeds correspond to TIMKEN technical data for 22222KEJW33.

What does 22222 KEJW33 mean?

The complete designation identifies important dimensional and construction characteristics of the bearing:

• 22222 - spherical roller bearing series and size
• K - tapered bore
• EJ - TIMKEN bearing design with steel cage
• W33 - lubrication feature in the outer ring
• TIMKEN - bearing manufacturer
• 110x200x53 mm - principal bearing dimensions

The suffixes are technically important. A replacement should therefore not be selected solely from the basic 22222 designation.

Tapered bore K 1:12

The K suffix in 22222 KEJW33 identifies a tapered bore.

For this bearing design, the bore taper is 1:12.

This is an important difference compared with a corresponding bearing manufactured with a cylindrical bore.

A tapered-bore spherical roller bearing can be mounted in an appropriately designed arrangement, including applications using suitable mounting components.

When selecting a replacement, the bore design must be checked. Identical 110x200x53 mm dimensions alone do not establish interchangeability between cylindrical-bore and tapered-bore versions.

Spherical roller bearing construction

Spherical roller bearings use two rows of rollers operating between the inner-ring raceways and a common spherical outer-ring raceway.

This geometry gives the bearing its self-aligning capability and allows it to accommodate angular misalignment between the shaft and housing within the limits specified for the bearing and application.

This type of construction is particularly useful where operating conditions may involve:

• high radial loads
• combined radial and axial loads
• shaft deflection
• mounting-related misalignment
• heavy industrial operating conditions

Self-alignment does not eliminate the need for correct mounting, fits, lubrication and alignment of the complete bearing arrangement.

Steel cage - EJ design

TIMKEN classifies 22222KEJW33 as a spherical roller bearing with a steel cage.

The EJ design incorporates TIMKEN's internal bearing geometry and steel cage construction.

The cage is an important part of the bearing because it separates and guides the rolling elements.

When comparing alternatives, the cage design should be considered together with the bearing dimensions, bore type, internal design, clearance and lubrication arrangement.

What does W33 mean?

W33 identifies a lubrication feature in the bearing's outer ring designed to facilitate relubrication.

This feature is particularly relevant in industrial bearing arrangements where periodic lubricant replenishment is required.

Relubrication can be important in applications involving:

• continuous operation
• high loads
• demanding industrial environments
• restricted access after installation
• planned preventive maintenance

The lubricant type, quantity and relubrication interval should be selected according to the operating conditions and TIMKEN engineering recommendations.

Load ratings of TIMKEN 22222 KEJW33

According to TIMKEN technical data:

Dynamic radial load rating C: 555 kN

Static radial load rating C0: 653 kN

These values are engineering ratings and should not be interpreted as the automatically permissible operating load for every application.

Correct bearing selection depends on factors including:

• radial load
• axial load
• load direction
• operating speed
• required bearing life
• lubrication
• operating temperature
• contamination
• shaft and housing fits
• mounting conditions

Bearing life and application suitability should be calculated using the appropriate engineering procedures.

Speed ratings

TIMKEN specifies the following thermal reference speeds:

• oil lubrication: 3500 rpm
• grease lubrication: 2900 rpm

These values are reference parameters rather than universal maximum operating speeds for every installation.

Actual permissible operating speed depends on the complete bearing arrangement, including load, lubrication, temperature, fits and heat dissipation.

22222 KEJW33 vs 22222

The basic designation 22222 identifies the bearing series and size, but KEJW33 specifies important construction features.

When selecting an equivalent bearing, verify:

• dimensions 110x200x53 mm
• tapered bore
• 1:12 bore taper
• internal bearing design
• cage construction
• W33 lubrication feature
• required internal clearance
• dynamic load rating
• static load rating
• operating speed
• lubrication requirements

A standard 22222 bearing should not automatically be considered a direct replacement for 22222 KEJW33 solely because its principal dimensions are identical.

How to select a replacement for 22222 KEJW33

Before selecting an equivalent bearing, verify:

• 110 mm bore diameter
• 200 mm outside diameter
• 53 mm width
• double row spherical roller construction
• tapered bore
• 1:12 taper
• cage construction
• lubrication arrangement
• required internal clearance
• dynamic load rating
• static load rating
• operating speed
• mounting arrangement
• lubrication requirements
• requirements of the specific machine

Dimensional compatibility alone does not always mean complete functional interchangeability.

Typical applications of spherical roller bearings

Spherical roller bearings are widely used in industrial machinery where high loads and potential shaft-to-housing misalignment need to be accommodated.

Typical application areas for this bearing category include:

• conveyors
• crushers
• screening equipment
• industrial gearboxes
• mining machinery
• material handling equipment
• paper machinery
• industrial fans
• process equipment
• heavy production machinery
• bulk material handling systems
• maintenance and repair operations

These are typical applications of spherical roller bearings as a product category. They do not confirm that TIMKEN 22222 KEJW33 is specified for a particular machine, OEM number or installation.

Installation of TIMKEN 22222 KEJW33

A spherical roller bearing with a tapered bore requires controlled installation.

Important considerations include:

• cleanliness of all components
• condition of mounting surfaces
• correct bearing seating
• correct shaft and housing fits
• controlled movement on the tapered seat
• correct internal clearance after mounting
• appropriate lubrication
• protection of raceways and rollers from damage

Mounting forces should not be transmitted through the rolling elements.

For large spherical roller bearings, appropriate mounting procedures and tools should be used for the specific bearing arrangement.
