DIN 981 GB812 Industrial Bearing Locknuts ISO4H M4-M65
Yokelink DIN 981 bearing locknuts are bearing accessories for screw drives. DIN 981 bearing locknuts are used to achieve a defined axial preload in axial angular contact ball bearings for screw drives and axial/radial roller bearings for screw drives.
DIN 981 bearing locknuts are also used in other applications where high axial forces must be supported and high axial runout accuracy and rigidity are require
DIN 981 bearing locknuts are used where high axial forces must be supported and high axial runout accuracy and rigidity are required, The thread and the axial face of the locknut in contact with the rolling bearing are produced in a single clamping operation. DIN 981 bearing locknuts allows very high axial runout accuracy to be achieved. The available bearing locknuts AM, ZM and ZMA can be used several times if handled correctly.

DIN 981 Bearing Lock Nuts Applications:
DIN 981 bearing lock nuts are widely applied in mechanical systems requiring reliable anti-loosening for rolling bearings. In the automotive field, they fix wheel hubs and engine components, withstanding vibrations from road conditions to ensure safety. For agricultural machinery operating in harsh environments. In construction machinery like excavators and tower cranes, they suit high-vibration scenarios. The power industry uses them in wind turbines to fix bearings against long-term wind-induced vibrations.
The Difference Between DIN 981 Bearing Lock Nuts And Ordinary Nuts
| Comparison dimensions |
DIN 981 Bearing Locknuts |
Ordinary nut |
| Appearance |
Round, with grooves/lugs on the outer circumference, suitable for special tools |
Mostly hexagonal, operated by universal wrench |
| Thread |
Fine pitch, anti-loosening design |
Coarse pitch or fine pitch, anti-loosening requires additional accessories |
| Function |
Axial positioning, bearing fixing |
General connection and tightening |
| Precision requirements |
Higher, need to match the bearing installation tolerance |
Lower precision level |
Buy DIN 981 Bearing Locknuts from Yokelink
The most secure design is no good when the screw joint breaks down later. Precise analysis of prevailing types of load and properties is therefore very important. This will decide whether locknuts compliant with DIN 981, 6923, 6927 or a self-locking slotted nut with a polyamide ring will ensure the right connection.
