The 30TAC62BDGG is a dedicated 60° angular contact thrust ball screw bearing with standardized 30×62×15mm dimension specification. Crafted from premium vacuum-refined GCr15 bearing steel, it undergoes ultra-precision raceway grinding and strict tolerance calibration to achieve P4/P5 high precision grade. Its exclusive 60° contact angle structure delivers dominant axial load resistance and rigid directional support, perfectly matching the unidirectional thrust characteristics of ball screw transmission. The optimized internal ball arrangement achieves even stress distribution, effectively suppressing micro deformation under sustained dynamic load. Matched with high-stability anti-deformation structural design, this model maintains consistent rotational accuracy and low runout performance during long-term high-frequency cyclic operation, with excellent resistance to mechanical fatigue and thermal drift. The sealed BDGG configuration locks internal lubrication steadily, preventing dust intrusion and lubricant deterioration to extend continuous service cycles.

Applications
- Heavy-Duty Industrial Rotary & Lifting Equipment
- Engineered to withstand extreme working conditions with heavy downward thrust, these bearings are widely deployed in heavy-duty industrial equipment, including large indexing tables, oilfield rotary tables and high-speed vertical motors. Thanks to the exclusive 60° large contact angle design, the bearings possess exceptional axial thrust resistance and structural durability. The optimized internal structure evenly disperses high axial pressure and alternating impact loads, effectively avoiding structural fatigue, deformation and early failure under long-term heavy-load operation, greatly improving the reliability and service life of heavy rotary and vertical transmission equipment.
- High-Speed Vertical Motor & Servo Transmission Equipment
- Perfectly suited for high-speed vertical motors and precision servo drive systems, these bearings feature low friction, ultra-low vibration and excellent dynamic stability. They reliably resist continuous axial tension and downward thrust generated during high-frequency shaft rotation, maintaining consistent shaft precision and smooth operation with minimal noise and vibration. They are widely adopted in high-speed vertical servo motors, precision drive motors and automated power equipment,supporting high-response, high-stability and high-precision motor operation.

A: Within the valid warranty period, if the product fails to meet the stipulated quality standards or cannot work normally due to inherent manufacturing quality problems (excluding human damage and improper use), the product shall be covered by free warranty service.
Q5: What are ball screw support bearings, and how do they differ from ordinary bearings?
A: Ball screw support bearings are specialized precision bearings designed exclusively for linear transmission systems. Unlike standard bearings focused on simple rotary movement, they are engineered to withstand high axial loads, maintain minimal axial runout, and sustain rigid positioning. They deliver superior rigidity and repeat accuracy to match high-precision linear motion demands of automation and machine tools.
Q6: What precision grades are available for ball screw support bearings?
A: They are available in multiple precision levels including P0, P6, P5 and P4. Higher-grade models feature stricter dimensional tolerance, lower runout error and better consistency, fully meeting high-end precision machining and ultra-precision positioning requirements.
