Sealed & Shielded Deep Groove Ball Bearing
Pre-lubricated Maintenance-Free
Sealed (2RS) and shielded (ZZ) variants provide built-in contamination protection and pre-lubricated convenience, ideal for harsh environments and maintenance-free operations.
- Shield Type (ZZ): Metal shields, low friction, high-speed capable
- Seal Type (2RS): Rubber contact seals, superior dust/moisture protection
- Available Series: 6000, 6200, 6300, 61000
- Operating Temp (Standard): −20 to +120 °C
- Lubrication: Factory pre-filled high-performance grease
- Speed Rating: 50–60% of open bearing rating (sealed)

Custom & Integrated Bearing Solutions
Integrated Assemblies Engineering Support
Beyond standard catalog sizes, BOM Bearing designs and manufactures custom bearing solutions — including integrated assemblies where the bearing and its mating components are produced as a single precision unit.
- Integrated Assemblies: Bearing and mating parts (shaft sleeve, housing, mounting flange) manufactured as one unit — more compact structure, smaller envelope, higher load capacity for the same space
- One-Piece Machining Precision: Integrated machining eliminates assembly stack-up errors between components, delivering higher combined precision than separately assembled parts
- Dimension Customization: Non-standard bore, OD, width, and inch dimensions outside catalog ranges
- Material & Treatment: Special steels, stainless, ceramic elements, custom coatings and heat treatments
- Sealing & Lubrication: Custom seal types, lubricant specifications, and operating temperature ranges
- Precision Grade: P0 (Normal), P6, P5, P4 to match application requirements

Frequently Asked Questions (FAQ)
What is the difference between the 6000, 6200, and 6300 series?
They differ mainly in cross-section size and load capacity for the same bore diameter. The 6000 series is the most compact, 6200 offers higher load capacity with a slightly larger OD, and 6300 provides the heaviest load capacity with the largest cross-section. The dimension table above shows all three series side by side for each bore size — making it easy to compare options for your application.
Should I choose shielded (ZZ) or sealed (2RS) bearings?
Shielded (ZZ) bearings use non-contact metal shields with lower friction, suitable for high-speed and clean environments. Sealed (2RS) bearings use rubber contact seals for superior dust and moisture protection, ideal for harsh or contaminated environments. Sealed bearings have a lower speed rating (50–60% of open type).
Can deep groove ball bearings handle axial loads?
Yes, deep groove ball bearings can accommodate both radial loads and moderate axial loads in both directions, thanks to their deep raceway grooves. However, for heavy axial loads, angular contact ball bearings or thrust bearings are recommended.
What clearance grade should I select (C2, CN, C3, C4)?
CN (Normal) is the standard clearance for most applications. C3 (greater than normal) is recommended for high-temperature environments or tight interference fits. C2 (less than normal) is used for precision applications with minimal play. C4 is for extreme temperature differentials.
Can BOM provide custom deep groove ball bearings?
Yes. Standard customization includes special dimensions, precision grades (P0 through P4), internal clearance classes (C2–C4), cage materials (pressed steel, brass, polyamide), sealing options, and special surface treatments. Beyond that, we design and manufacture integrated bearing assemblies — where the bearing and mating components (shaft sleeve, housing, flange) are machined as a single precision unit. This delivers a more compact structure with higher load capacity, and eliminates assembly stack-up errors for superior combined precision. Contact us to discuss your application.
