Custom 6800 Series Deep Groove Ball Bearing Manufacturers, Factory

6800 Series

6800 Series Deep Groove Ball Bearing is a common bearing type. Its inner diameter is usually 10mm, outer diameter is 19mm, and width is 5mm. This series of bearings has the characteristics of simple structure, easy use and high reliability. It is widely used in various mechanical equipment, such as construction machinery, packaging machinery, bearing broaching machines, automotive lights, etc. In addition, depending on the brand and model, this series of bearings may also have designs such as dust covers or sealing rings to meet the needs of different scenarios.

P5 AVAILABLE

THIN SECTION

The 6800 Series deep groove ball bearing occupies the thin-section segment of the standard deep groove range, positioned between the ultra-thin 6700 line and the heavier 6900 line. For B2B buyers, this means reduced cross-section height and weight per bore size, which matters in motor end brackets, instrument spindles, and compact gearbox layouts where axial and radial space is pre-determined by the housing design. Bore sizes run from 10 mm to 50 mm. Standard production uses pressed steel cages, with polyamide cages selected for lower noise or higher speed positions. Clearance class CN is supplied as standard, while C3 and C4 are available at order confirmation. Open, ZZ, and 2RS configurations share the same boundary dimensions.

Reduced section height

Thinner rings than the 6900 line allow tighter axial packaging without changing bore diameter or shaft fit.

Weight reduction per position

Lower mass per bearing contributes to reduced rotating inertia in high-speed motor and spindle applications.

Shared dimensional platform

Sealing and clearance variants use identical boundary dimensions, so one part number family covers multiple assembly lines.

Repeatable batch output

Fixed process parameters per production batch keep running accuracy and clearance within agreed tolerance bands across orders.

Purchasing questions

What separates the 6800 series from the 6900 series in practice?

The 6800 series uses thinner rings for the same bore, which lowers section height and weight but reduces load capacity compared with the 6900 line. Selection depends on whether housing space or load margin is the binding constraint.

Is P5 precision available across the full size range?

P5 precision is produced for most sizes in the series, with availability confirmed per line item at order stage. P6 is held in broader stock coverage for faster delivery.

Can polyamide cages be substituted for existing steel-cage part numbers?

Cage substitution is reviewed against the operating temperature and speed limits of the application. Polyamide cages are selected when lower noise or reduced weight is the priority, provided the temperature ceiling is respected.

What documentation accompanies bulk orders?

Bulk shipments include batch number records, dimensional inspection reports, and material certificates. Additional documents for incoming inspection can be arranged when the purchase order is confirmed.

Warehouse and assembly notes

Thin ring handling

Thin-section rings deform more easily under point loads. Support the bearing evenly during press fitting and avoid concentrated force at a single point on the outer ring.

Interference fit limits

Keep interference within recommended ranges. Excessive press fit on thin rings changes internal clearance and raises running temperature after assembly.

Storage of shielded variants

Keep sealed cartons closed until line-side issue. Temperature cycling while packaging is open can draw moisture into the shield gap.

Lubrication for open types

Match grease base oil viscosity to operating speed and ambient temperature. Sealed variants are filled at production and need no pre-assembly lubrication.
