Double-row Angular Contact Ball Bearing 3311

No manufacturer wishes to endure production downtime caused by a single minor component. For continuously operating machinery, the Double-row Angular Contact Ball Bearing 3311 is more than just a spare part – it is the decisive element for maintaining productivity and operational stability. Whether you are a factory owner requiring a dependable supply source or a technical engineer seeking to secure equipment longevity, the solution from Bejako – the authorized distributor of ZWZ bearings – provides absolute assurance of genuine products, complete CO/CQ certification, extended warranty, and clear commitments.

Advantages & benefits of ZWZ 3311 bearings – why should you choose them?

The ZWZ Double-row Angular Contact Ball Bearing 3311 is the optimal ion for heavy-load applications due to its robust performance, superior load-bearing capacity, and transparent warranty policy.

In industrial plants, bearing failures not only cause costly downtime but also create concerns regarding project deadlines and accountability. Maintenance engineers, in particular, often fear inadvertently procuring counterfeit or substandard products lacking valid CO/CQ documentation, directly jeopardizing production lines and professional reputation.

The ZWZ 3311 bearing eliminates these risks comprehensively. With its dual-row angular contact design, the product sustains both radial and axial loads in both directions, as well as tilting moments – making it ideal for equipment such as pumps, gearboxes, and compressors.

Premium cage materials and precision-finished surfaces reduce friction and heat generation, thereby extending the lifespan of lubricants and bearings alike. Certain models also feature sealed designs, requiring no maintenance – saving both cost and time.

This product also demonstrates exceptional reliability: service life increases by up to 50% thanks to advanced design and premium materials. ZWZ produces its own steel under rigorous quality control, consistently valued by Vietnamese engineers for its operational stability, low vibration, and transparent CO/CQ certification with reliable warranty terms.

For those requiring a long-term, trustworthy solution with comprehensive 24/7 technical support, the ZWZ 3311 is the option to be considered.

Technical specifications & product features of Double-row Angular Contact Ball Bearing 3311

The ZWZ 3311 double-row angular contact ball bearing features standard dimensions of 55×120×49.2 mm, a dynamic load rating of approximately 105–112 kN, and is manufactured from high-grade chromium steel GCr15. It is fully interchangeable with equivalent models from SKF, FAG, and NSK.

• Material & construction: ZWZ employs internationally standardized chromium steel (GCr15 / AISI 52100), with optional ZZ/2RS seals providing enhanced dust and lubricant resistance. SKF and FAG offer certain advantages with metal shields and polyamide cages, suited for heavy dust environments.

• Certification & reliability: ZWZ complies with ISO 9001:2008/2015 standards however, unlike SKF/FAG, independent test data is not widely published. For projects requiring technical substantiation, CO/CQ certification should be requested from the distributor.

• Interchangeability & investment efficiency: With equivalent technical parameters and transparent CO/CQ availability, the ZWZ 3311 is a cost-efficient alternative for small to medium-sized factories requiring rapid delivery, competitive pricing, and assured standard performance.

Usage guidelines & practical application advice for ZWZ Double-row Angular Contact Ball Bearing 3311

1. Preparation before installation

• Verify the correct product code and technical specifications.

• Clean shafts, housings, and bearings to remove impurities.

• Inspect all contact surfaces for damage or wear.

2. Proper installation

• For sealed bearings, avoid washing for open types, ensure thorough cleaning.

• Do not strike the bearing directly – use pressing tools or controlled heating (max. 120°C).

• When applying grease, fill only 30–50% of the housing volume.

• Ensure shaft and housing concentricity to prevent misalignment overload.

3. Periodic maintenance

• Regularly monitor noise, vibration, and operating temperature.

• Re-lubricate if grease dries, becomes contaminated, or equipment remains idle for extended periods.

• Conduct scheduled inspections and replace bearings showing signs of pitting, wear, or corrosion.

4. Practical applications

• Wind energy: ZWZ bearings have successfully replaced foreign brands, operating reliably in 2.0–2.5 MW turbines.

• Heavy industries – cement, steel: Commonly applied in gearboxes, conveyors, and crushers, highly valued for robustness and rapid delivery capability.

• Trucks and large motors: Ensures durability in high-vibration and heavy-load environments.
