Double Row Angular Contact Ball Bearings
Double-row angular contact ball bearings, a pivotal component in mechanical transmission, feature a distinctive double-row ball structure. This design empowers them to handle substantial radial and bidirectional axial loads concurrently, ensuring seamless and stable operation of your equipment.
Robust Performance for Demanding Conditions
Engineered to excel in challenging environments, our bearings offer:
| Performance Aspect | Technical Advantage | Benefit for Your Equipment |
| Heavy-load Handling | Double-row ball configuration | Supports machinery under extreme loads without compromising stability |
| High-speed Efficiency | Low-friction rolling elements | Reduces energy consumption, extends equipment lifespan |
| Precision Assurance | Exceptional rigidity | Maintains machining accuracy in high-precision applications |
Diverse Types for Every Need
(1) Cage Materials
Glass Fiber Reinforced Nylon 66: Lightweight, self-lubricating, and wear-resistant, with minimal temperature rise during operation. Ideal for precision equipment with strict temperature control requirements.
Stamped Steel Cage: Low cost and good formability, suitable for mass production and conventional working conditions.
Brass Solid Cage: High strength and excellent wear resistance, providing stable support for balls in heavy-load and complex working conditions.
(2) Dust-proof and Sealing Types
Non-contact Dust Covers: Effectively block dust and impurities from entering the bearing, reducing friction and wear. Suitable for general contaminated environments.
Contact Seals: Strong sealing performance prevents lubricant leakage and external contaminant intrusion. Ideal for harsh environments with high pollution or humidity. Pre-lubricated for maintenance-free use and convenient installation.
(3) Bearing Material Options
| Material Type | Composition & Traits | Application Highlights |
| Bearing Steel | GCr15, GCr15SiMn High hardness, wear-resistance | Widely used across industries Cost-effective choice |
| Stainless Steel | Corrosion-resistant alloys | Food processing, chemical equipment Ensures longevity in harsh conditions |
| Hybrid Ceramic | Ceramic rolling elements + steel rings Low friction, high hardness | High-speed machinery, precision equipment |
| Full Ceramic | All-ceramic construction Low density, non-magnetic | Aerospace, semiconductor manufacturing Performs in extreme environments |
Superior Quality from Fine Craftsmanship
Premium Materials: Strict selection of high-quality raw materials ensures product quality from the source.
Advanced Manufacturing: Cutting-edge equipment and leading processes are used to strictly control every production step.
Precision Testing: Each bearing undergoes multiple rigorous tests (load capacity, high-speed operation, sealing performance, etc.) before delivery to ensure reliable quality.
Extensive Applications for Industrial Progress
Double-row angular contact ball bearings are widely used in industrial fields due to their excellent performance and reliability:
Machine Tool Industry: Support machine tool spindles to ensure high machining precision and stability.
Motors and Pumps: Support rotor shafts and pump shafts, adapting to high-speed rotation and improving equipment efficiency and lifespan.
