High-precision, single-row deep groove ball bearings from the 6900 series, designed for applications requiring high speed and low friction.
Deep Groove Ball Bearing 6900 Series
The 6900 series deep groove ball bearings are a versatile and widely used type of rolling bearing. They are characterized by their simple design, non-separable rings, and suitability for high speeds. These bearings are capable of handling both radial and axial loads in both directions. Their deep raceway grooves and close conformity between the raceway grooves and the balls enable them to accommodate moderate axial loads in addition to radial loads. Available in various sizes and sealing configurations (open, shielded, sealed), they are ideal for a broad range of agricultural machinery, industrial equipment, and general mechanical applications where reliability and performance are critical.
Ensure proper alignment during installation to prevent premature wear. Use appropriate tools for mounting and dismounting. Lubricate according to manufacturer specifications and operating conditions. Avoid excessive impact loads. Store in a dry, clean environment to prevent corrosion.
High speed capability, low friction, versatile for combined loads, durable and reliable, available in various sealing options for different environments.
Improper installation can lead to bearing failure. Over-lubrication or under-lubrication can reduce lifespan. Do not expose to extreme temperatures or corrosive chemicals without proper protection.
Consider the required load capacity (radial and axial), operating speed, temperature range, and environmental conditions (dust, moisture) when selecting a 6900 series bearing. Choose appropriate sealing options (open, Z, ZZ, RS, 2RS) based on the application. Consult product specifications for exact dimensions and tolerances.
Standard import duties and taxes apply as per Pakistan Customs Tariff for ball bearings. Ensure proper documentation including invoice, packing list, and bill of lading/airway bill. Compliance with PSQCA standards may be required.
Importer must have a valid NTN and be registered with relevant authorities. Check for any specific import restrictions or licensing requirements for industrial components. Ensure product quality certificates are available.
Compliance with destination country's import regulations is crucial. Ensure proper labeling and packaging for international shipping. Export documentation includes commercial invoice, packing list, and certificate of origin.

- What are the main characteristics of 6900 series deep groove ball bearings?
- The 6900 series deep groove ball bearings are known for their compact design, ability to handle high speeds, and capacity to support both radial and moderate axial loads. They are also available in various sealing options.
- How do I choose the correct 6900 series bearing for my application?
- Consider factors such as load capacity, operating speed, temperature range, and environmental conditions. For dusty or wet environments, choose sealed (2RS) or shielded (ZZ) versions. Always refer to the product's technical specifications.
- What is the difference between shielded (ZZ) and sealed (2RS) bearings?
- Shielded (ZZ) bearings have metal shields that protect against larger debris but do not offer a complete seal against liquids. Sealed (2RS) bearings have rubber seals that provide better protection against dust, dirt, and moisture, making them suitable for harsher environments, though they may have slightly higher friction.
- Can these bearings handle axial loads?
- Yes, deep groove ball bearings, including the 6900 series, are capable of handling moderate axial loads in both directions in addition to radial loads, due to their deep raceway grooves.
