Product Description

 
                                                     
Slewing Bearing
Slewing bearing introduction
               
Slewing bearing is also called slewing ring,  turntable bearing, and rotary table bearing.
Slewing bearing is a bearing that able to bear axial load, radial load and overturning torque.
Under normal circumstances, slewing bearing has their own mounting holes, lubricant holes and seal holes, to meet the different needs of the various host working under the various conditions.
On the other hand, slewing  bearing  has characteristics of compact structure, guide rotating convenient, easy to install and maintaining easily.

The Core Elements of Bearing Quality

Material Properties

Steel Quality: High-carbon chromium bearing steel (e.g., GCr15) must possess high hardness, wear resistance, and fatigue resistance.
Heat Treatment Process: The hardness after quenching and tempering should reach HRC 58-64, ensuring a reasonable hardness gradient between the surface and the core.
Cleanliness: Non-metallic inclusions (e.g., oxides, sulfides) must comply with ISO 4967 standards (e.g., A/B/C inclusion levels ≤ Grade 2).
Machining Accuracy

Dimensional Tolerances: Inner diameter, outer diameter, and width must meet ISO 492 or ABEC standards (e.g., ABEC Grade 7 tolerances are at the micron level).
Geometric Accuracy: Roundness, cylindricity, and parallelism errors must be controlled within 0.5-3μm.
Surface Roughness: Raceway surface Ra ≤ 0.05μm to reduce friction and wear.
Lubrication and Sealing

Grease must meet high-speed and high-temperature conditions (e.g., NLGI Grade 2, base oil viscosity at 40°C between 100-150cSt).
Seals (contact/non-contact) must be dustproof and waterproof (e.g., IP rating such as IP6X).
Dynamic Performance

Fatigue Life: Calculated through L10 life (e.g., rated life of 1 million revolutions), actual testing must comply with ISO 281 standards.
Vibration and Noise: Z1/Z2/Z3 classification (Z1 level vibration speed ≤ 0.8mm/s).
