Spherical Roller Bearing Replacement Made Easier: Complete NTN-SNR SRB KIT Solutions

A spherical roller bearing replacement often requires more than just the bearing itself.

A withdrawal sleeve, locating rings, seals and, if necessary, a bearing housing may also be required. In addition, all these components need to be properly matched to each other.

What if you didn’t have to select all the required components separately every time?

This is where NTN-SNR SRB KITs offer a practical solution. The matching components required for a specific maintenance task are supplied together in a single kit, available under one part number.

Why Choose an SRB KIT?

When carrying out maintenance, selecting the right bearing is only part of the task. It is equally important to ensure that all additional components required for installation are available.

One of the key advantages of the NTN-SNR SRB KIT concept is therefore its simplicity.

One part number
The KIT can be ordered and stored under a single reference.

Matching components
The specific components required for the bearing are included in the KIT, reducing the risk of selecting incorrect parts or overlooking a necessary component.

Simplified maintenance preparation
All required components are supplied together in one KIT, reducing the number of individual parts that need to be handled.

The advantage is therefore not simply that several components are supplied in one package. The KIT can simplify the entire process, from purchasing and inventory management to maintenance preparation.

3 Maintenance Scenarios – 3 NTN SRB KIT Solutions

NTN offers three different KIT configurations depending on whether the existing bearing housing can continue to be used, a complete bearing housing replacement is required, or automatic lubrication is also needed.

1. If the Bearing Housing Remains: Sealed Spherical Roller Bearing KIT

If the existing bearing housing is in good condition and can continue to be used, there is no need to replace it.

For this situation, NTN offers a sealed spherical roller bearing KIT designed for partial maintenance.

The KIT includes:

• sealed spherical roller bearing,
• withdrawal sleeve,
• 2 locating rings,
• technical instructions for internal clearance adjustment by axial displacement and relubrication.

When can this be a good choice?
When the bearing arrangement needs to be refurbished while the existing bearing housing is still in good condition and can remain in use.

2. If the Bearing Housing Also Needs to Be Replaced: SNC Plummer Block + Sealed Spherical Roller Bearing KIT

If the bearing housing also needs to be replaced, NTN offers a complete solution.

The SNC split plummer block + sealed spherical roller bearing KIT includes the housing, bearing and the required related components in a single kit.

The KIT includes:

• 1 SNC split plummer block
• 1 sealed spherical roller bearing
• 1 withdrawal sleeve
• 2 locating rings
• 2 sets of double-lip rubber seals
• 1 plug
• technical instructions

When is this version worth considering?
When a complete bearing housing replacement is required and a sealed spherical roller bearing is preferred.

3. Complete Bearing Housing Solution with Automatic Lubrication

What if, in addition to a complete bearing arrangement, you also want to ensure a regular supply of lubricant?

The third SRB KIT offers a solution for this requirement.

The KIT includes an SNC split plummer block, a standard open spherical roller bearing and a DRIVE BOOSTER automatic lubrication system.

The KIT includes:

• 1 SNC split plummer block
• 1 standard open spherical roller bearing
• 1 withdrawal sleeve
• 2 locating rings
• 2 sets of rubber seals
• 1 plug
• 1 DRIVE BOOSTER automatic lubrication system
• technical instructions

When is this version worth considering?
When a complete bearing housing solution is required and automatic lubrication is also part of the maintenance strategy.

What Should You Know About the Sealed Spherical Roller Bearing Solution?

One of the key components of the first two KITs is the sealed spherical roller bearing.

The sealed design can be particularly beneficial in applications where the bearing arrangement may be exposed to dust, moisture or other contaminants.

Among the application areas for SRB KITs, NTN-SNR highlights mining and quarrying, woodworking, steel production, agriculture and food processing.
