What is a single row deep groove ball bearing

 

 

Single row deep groove ball bearing is a kind of mechanical component widely used in high speed and low noise environment. Its structure mainly bears radial load and supports certain axial load through the inner and outer ring groove design. The bearing provides a variety of sealing forms, including dust cover type and rubber seal ring type. The type with seal ring is pre-sealed with high-quality grease to reduce friction torque. It is suitable for motors, gear devices, mechanical arms, automobile manufacturing, air compressors, agricultural machinery and other fields

Inner & Outer Rings

 

Function: The core structure that carries the load and provides the moving track for the rolling body.

Structural details:
Groove design: The inner and outer ring raceways are continuous deep arc grooves (radius of curvature ≈ 51.5%-53% of the ball diameter) to ensure smooth rolling of the balls.


Material: High carbon chromium bearing steel (such as GCr15), quenching hardness reaches 60-64 HRC.


Surface treatment: The raceway is super-finished, with a roughness of ≤Ra 0.05μm to reduce friction loss.
Key features: The inner ring has an interference fit with the shaft, and the outer ring has a transition fit with the bearing seat.

Rolling Elements：Steel Ball

Function: Core medium for transmitting loads, reducing friction by rolling.
Technical parameters:
Material: AISI 52100 bearing steel (conventional) or AISI 440C stainless steel (corrosion resistant).
Precision: G10 grade (diameter tolerance ±0.5μm), spherical error ≤0.08μm.


Quantity: Arranged according to the "Z+2" formula (Z is an integer) to ensure uniform load distribution.
Special variant: Ceramic balls (Si₃N₄) are used for high-speed/insulation scenarios.

Cage/Retainer

Function: Separate steel balls, maintain uniform spacing, and prevent collisions

type：

Stamped steel cage: 08F low carbon steel (phosphating treatment), General industrial equipment (optimal cost)

Engineering plastic cage :PA66 + 30% glass fiber reinforced, High speed conditions (dm n value > 1 × 10⁶).

Machined copper cage: HPb59-1 lead brass ,High temperature/vacuum environment (resistant to 350℃).

1748837684799
Lubrication

Function: Reduce friction and wear, dissipate heat and prevent rust.

Lubrication method:

Grease lubrication (accounting for 90% of applications):

Pre-filled with high-temperature lithium-based grease (NLGI grade 2) with MoS₂ additive.

Maintenance-free life: 10,000 hours (normal working conditions).

Oil lubrication:

Synthetic hydrocarbon oil (ISO VG 10-32) for high-speed scenes.

Solid lubrication:

Microporous polymer absorbs lubricating oil to prevent leakage (special for food machinery).

Seals/Shields

Function: Prevent contaminants from entering and retain lubricants.
