Radial Insert Ball Bearings with Eccentric Locking Collar

INA from Schaeffler classic radial insert ball bearings are located on the shaft with a locking collar. They are suitable for bearing arrangements with a constant direction of rotation or, under low speed and load, for an alternating direction of rotation.

The locking collar is preferably tightened in the direction of rotation and secured with a grub screw. This location method prevents damage to the shaft and can be easily loosened again.

The P seal is two zinc-coated sheet steel washers with intermediate NBR part, seal lip axially preloaded.

The R seal is two zinc-coated sheet steel washers extended outwards and angled downwards with intermediate NBR part and radially preloaded seal lip. Better protection against mechanical damage.
Substantial grease reservoir due to the space between the extended and angled sheet steel washers. Used in radial insert ball bearings with inner ring extended on both sides.

To protect the seal lip from mechanical damage, the outer sheet steel washer extends a considerable distance down towards the bearing inner ring.

In addition to bearings with a spherical outer ring (GRAE..-NPP-B and GE..-KRR-B), there are also cylindrical (RAE..-NPP and RALE..-NPP)

Features and Benefits

• Lower operating costs

• Reduced maintenance due to improved lubrication

• Lower heat generation

• Less noise

• Protected against fretting corrosion

• Shaft diameters from 12 mm to 60 mm (RAE..NPP) and (GRAE..-NPP-B)

• Shaft diameters from 20 mm to 30 mm (RALE..NPP)

• Shaft diameters from 17 mm to 120 mm (GE..-KRR-B)

Suffixes

FA106 - Bearing subjected to special noise testing

B - Bearing with special outer ring

NPP - Lip seals on both sides (P type seal)

KRR - Lip seals on both sides (R type seal)

What are the key advantages of using a steel construction for these inserts?

Steel construction provides increased strength and wear resistance, enhancing the overall longevity of the inserts and ensuring reliability under substantial loads.

How do static and dynamic load ratings affect operational efficiency?

The static load rating indicates the maximum load the bearing can support without moving, while the dynamic load rating denotes the maximum load it can sustain while in motion. Understanding these ratings is crucial for selecting the right bearing for specific applications, thus preventing premature failure.

What factors should be considered when selecting a bearing insert for industrial applications?

Consider the load ratings, material composition, compatibility with existing equipment, and the specific operational conditions, including temperature and speed parameters to ensure optimal performance and longevity.
