H 3130 FAG Adapter Sleeve 135x150x111 mm for Tapered Bore Bearings

What Is the H 3130 FAG Adapter Sleeve?

The H 3130 FAG is an adapter sleeve designed for mounting bearings with a 1:12 tapered bore onto cylindrical shafts. It provides a practical and precise method of locating the bearing without requiring a tapered shaft seat. The H3130 is designed for a 135 mm shaft diameter, has a nominal bearing bore diameter of 150 mm and an overall sleeve length of 111 mm. It is widely used in industrial bearing arrangements, heavy machinery, conveyors and maintenance applications.

What Is the H 3130 Adapter Sleeve Used For?

The H 3130 FAG adapter sleeve is used to mount bearings with tapered bores onto cylindrical shaft seats. This mounting method is widely used in mechanical engineering because it eliminates the need to machine a tapered bearing seat directly onto the shaft.

Typical applications include:

• Industrial machinery
• Conveyor systems
• Industrial fans
• Gear drives
• Agricultural machinery
• Production equipment
• Material handling systems
• Heavy-duty machinery
• Large bearing arrangements
• Maintenance and repair operations

1:12 Taper Design

The H3130 FAG features a standard 1:12 taper. During installation, the bearing is driven progressively onto the tapered surface of the sleeve.

As the bearing moves along the taper, its inner ring expands slightly and the bearing internal clearance is reduced. Correct drive-up is therefore essential for achieving the required fit without creating excessive preload.

Compatible Bearing Series

The H 3130 adapter sleeve can be used with suitable tapered bore bearings, including selected bearings from series such as:

• 20330 K
• 22230 K
• 23130 K

Compatibility should always be confirmed using the complete bearing designation and the technical requirements of the specific bearing arrangement.

KM30 Lock Nut and MB30 Lock Washer

The H 3130 mounting arrangement uses:

Lock Nut: KM30

Lock Washer: MB30

The lock nut is used to drive and secure the bearing on the tapered sleeve. The lock washer prevents unwanted rotation or loosening of the nut during operation.

Advantages of the H 3130 FAG Adapter Sleeve

Using an adapter sleeve provides several practical benefits:

• Mounting tapered bore bearings on cylindrical shafts
• Simplified shaft design
• Accurate bearing positioning
• Secure bearing location
• Easier installation and removal
• No tapered shaft seat required
• Suitable for large industrial bearing arrangements
• Convenient solution for maintenance and replacement

Installation of the H 3130 FAG

Before installation, the shaft, adapter sleeve and bearing bore should be carefully cleaned and inspected.

Check that:

• The shaft surface is clean and undamaged
• The sleeve is free from burrs and corrosion
• The bearing has the correct tapered bore
• The bearing and sleeve designations are compatible
• The correct lock nut and locking element are available

For spherical roller bearings, the bearing drive-up distance or reduction in radial internal clearance should be monitored according to the bearing manufacturer's mounting procedure.

Excessive drive-up can reduce internal clearance too much and negatively affect bearing operating conditions.

Applications in Maintenance and Mechanical Engineering

The H3130 FAG adapter sleeve is particularly useful in maintenance departments where large tapered bore bearings must be installed or replaced efficiently.

It is commonly found in bearing arrangements used in:

• Conveyors
• Crushers
• Industrial fans
• Processing machinery
• Agricultural equipment
• Production lines
• Drive systems
• Heavy industrial equipment

The adapter sleeve facilitates bearing replacement while allowing the use of a conventional cylindrical shaft seat.

Frequently Asked Questions (FAQ)

What shaft diameter is the H 3130 FAG designed for?
The H3130 is designed for a 135 mm cylindrical shaft.

What is the nominal bearing bore diameter?
The nominal tapered bearing bore diameter is 150 mm.

What thread does the H3130 have?
The sleeve uses an M150x2 thread.

What taper does the H 3130 use?
The H3130 has a standard 1:12 taper.

Which lock nut is used with the H3130?
The corresponding lock nut is KM30.

Frequently Asked Questions from Engineers and Mechanics

Which lock washer is used with H 3130?
The corresponding locking washer is MB30.

Can H3130 be used with a cylindrical bore bearing?
No. Adapter sleeves are designed for bearings with tapered bores mounted on cylindrical shafts.

Can H3130 be used with a 22230 K bearing?
Yes, H3130 is commonly associated with the 22230 K tapered bore bearing series. The complete bearing designation should still be verified before installation.

Why is bearing clearance checked during installation?
Driving a bearing onto the tapered sleeve expands the inner ring and reduces radial internal clearance. Monitoring this reduction helps ensure the bearing is neither too loose nor excessively preloaded.

Is shaft diameter alone enough to select an adapter sleeve?
No. The bearing designation, tapered bore dimensions, sleeve series, shaft diameter and locking components must all be checked.
