PRODUCT

Single Row Angular Contact Ball Bearing

In precision mechanical operations, angular contact ball bearings are critical for stable and efficient transmission. Our bearings, designed and crafted excellently, enhance equipment performance remarkably, ideal for various applications. 

Diverse Types for Every Need

(1) Single-Row 

• Unidirectional axial load. Balances forces during radial load; used for precision in transmissions and spindles.
• 4 contact angles (15°, 25°, 30°, 40°) for custom axial load handling.

(2) Double-Row

• High load capacity, ideal for heavy machinery; cuts maintenance. 

(3) Four-Point Contact Ball Bearings (QJ0000 Type)

Unique raceway design enables bidirectional axial load handling. They need less space than double-row bearings yet carry heavy loads, perfect for compact, high-demand equipment like precision instrument rotors.

Superior Quality from Fine Craftsmanship

(1) Material Selection

Premium bearing steel ensures high strength, wear resistance, and toughness. Special heat treatment maintains dimensional stability under heavy loads and high speeds, extending lifespan and cutting maintenance costs.

(2) Manufacturing Precision

Grades include P0, P6, P5, P4, P2 (P3/P7/P9 available per request). Tight tolerances ensure perfect fit with equipment, minimizing errors and boosting performance.

(3) Cage Design

Materials like brass and reinforced nylon match bearing types and conditions. Optimized designs reduce ball friction, improve lubrication, and lower noise/energy use.

 
Extensive Applications for Industrial Progress

 

(1) Machine Tools	(2) Automotive	(3) Aerospace	(4) Diverse Industries
Essential for machine tool spindles, our bearings ensure positioning and rotational precision, enhancing machining quality and reducing defects. They support efficient milling, turning, and grinding, driving industry-wide precision and productivity.	Used in transmissions, engines, and wheel hubs:   Transmissions: Manage complex loads for smooth power transfer and shifting. Engines: Withstand high speeds and loads for optimal performance. Wheel Hubs: Ensure stable high-speed rotation and road safety.	Crucial for aircraft engines and transmission systems, our bearings offer heat/pressure resistance, high-speed capability, and lightweight design. They deliver reliable operation in extreme conditions, vital for flight safety.	Medical: Enable precise, stable movements in healthcare equipment. Robotics: Facilitate flexible, accurate motion in robot joints. Power Tools: Enhance energy transmission efficiency and durability. Instruments: Guarantee measurement and inspection accuracy.

QUALITY

Material

Granville standard bearings are manufactured with 100Cr6 (Gcr15) grade steel, which ensures high levels in terms of 

√ Hardness
√ Wear Resistance
√ Resistance to Fatigue
√ Dimensional Stability
√ Mechanical Strength
√ Compressive Strength

This type of steel combined with heat treatment, is an excellent solution for various application. 

Cage

Lubrication

Special lubricating oil is commonly used. Its function is to reduce friction between the steel balls and the inner/outer rings inside the bearing, minimize wear, improve rotational smoothness, and extend the service life of the bearing.
