Germany DIN1804 DIN70852 Bearing Locking Nuts
DIN 1804 and DIN 70852 bearing locking nuts, designed to secure rotating shafts, bearings, and hub
connections. Bearing Locking Nuts are used to adjust axial play or secure shaft-hub connections in mechanical systems. Their flat design allows for space-saving
installation in tight spaces. DIN 1804 nuts are specialized for high-precision axial locking, particularly in bearing assemblies. They often work with hook wrenches (e.g., SKF HN series) for installation in confined spaces.
1. DIN 70852 Bearing Locking Nuts
DIN70852 bearing locking nuts are used to adjust axial play or
secure shaft-hub connections in mechanical systems. Their flat
design allows for space-saving installation in tight spaces .
DIN70852 bearing locking nuts Key Features:
Slotted Design: Slots enable precise adjustment using a spanner
(e.g., DIN 1810-A), ensuring the nut stays fixed under vibration.
Material & Finish: Typically made of steel (property class 17H)
with zinc plating or blue passivation for corrosion resistance .
Thread Sizes: Available in metric threads from M10×1 to M80×1.5.
Larger sizes (≥M45×1.5) have 6 slots for better torque distribution
.
DIN70852 bearing locking nuts Applications:
Industrial machinery, automotive drivetrains, and conveyor systems.
Examples: Securing gears, pulleys, or bearings on shafts.
2. DIN 1804 Bearing Locking Nuts
DIN 1804 bearing locking nuts are specialized for high-precision
axial locking, particularly in bearing assemblies. They often work
with hook wrenches (e.g., SKF HN series) for installation in
confined spaces
DIN 1804 bearing locking nuts Key Features:
Smooth Mating Surface (D3): A slightly protruding smooth surface
ensures tight contact with mating components, reducing wear.
DIN 1804 bearing locking nuts Material Options:
Unhardened steel (blackened finish) for general use.
Hardened steel (HRC 60±2) for heavy-duty applications requiring
high strength .
Nylon-insert variants (e.g., GN 1804.1) for self-locking
performance without additional tools .
Thread Sizes: Similar to DIN 70852, covering M10×1 to M80×1.5.
DIN 1804 bearing locking nuts Applications:
Bearings on tapered shafts, gearboxes, and precision machinery.
Example: Adjusting clearance in roller bearing assemblies .
DIN 70852 DIN1804 Bearing Locking Nuts Specifications:
DIN70852 DIN1804 Bearing locking nuts come in various sizes,
typically specified by their thread diameter and pitch, or
sometimes by a KM number for specific SKF lock nuts. Common metric
thread sizes include M3, M4, M5, M6, M8, M10, M12, M16, and M20.
Larger sizes like M25, M50, M60, and M85 are also available. To
determine the correct size, you'll need to measure the shaft
diameter the nut will be used on or the bore diameter of the nut
itself.
Why Choose DIN Standards for bearing locking nuts?
It ensure interchangeability and reliability across industries.
Widely used in automotive, aerospace, and industrial sectors (e.g.,
SKF, Ganter) .
Zinc plating and heat treatment enhance resistance to corrosion and
fatigue.
