Bearing Type: |
Thrust angular contact ball bearing (60°) - Ball screw support bearing |
Ball screw thrust angular contact bearings are composed of 5 core parts: inner ring, outer ring, steel balls, retainer (nylon cage), and sealing rings (optional).
| Component | Core Advantages |
|---|---|
| Inner Ring & Outer Ring | 1. Made of vacuum degassed bearing steel with ultra-precision ground raceway, low friction and low heat generation.2. 60° contact angle design brings high axial rigidity and strong axial load capacity.3. High hardness and great fatigue resistance, stable precision for long-time reciprocating movement.4. Precise dimensional tolerance for perfect matching in DB/DF/DT combined installation. |
| Steel Balls (Rolling Elements) | 1. Strict sphericity and consistent size for even load distribution without stress concentration.2. Tiny deformation under axial loads, smooth rolling to reduce vibration and running noise.3. Ensure stable high-speed feed movement of ball screws. |
| Modified Nylon Cage | 1. Light weight reduces rotational inertia and centrifugal force for steady high-speed operation.2. Self-lubricating property lowers abrasion and temperature rise, avoids precision loss caused by heat.3. Elastic buffer absorbs micro vibration and impact, cutting operation noise.4. Good oil storage, moisture and mild corrosion resistance for long lubrication intervals. |
| Non-contact Rubber Seals (Optional DDG Seal) | 1. Non-contact design adds almost no extra friction and retains high speed performance.2. Block dust, metal chips, coolant and moisture to protect internal rolling parts.3. Seal internal grease against leakage and volatilization, realizing long maintenance-free service. |
| Preload Matching Structure | 1. Matched ring tolerances support light / standard preload to remove all internal clearance.2. Eliminate axial backlash and motion hysteresis, guarantee micron-level repeated positioning accuracy. |

Excellent High-Speed Stability & Fast Response
Designed for high-speed reciprocating and frequent speed shifts, the bearing adopts low-friction lightweight nylon cages and super-finished raceways & steel balls. Mirror-smooth raceways cut friction torque, supporting steady high-speed running and quick acceleration/deceleration. It delivers lag-free, low-vibration transmission for frequent start-stop and fast feed of ball screws, while the refined internal structure suppresses heat buildup to sustain consistent dynamic performance over long operation.
Super Precision with Low Vibration & Noise
Produced to PN7B/P2 ultra-precision specs, the bearing boasts minimal runout and tight dimensional consistency. Each unit is fully tested for vibration and noise. Polished raceways and well-matched rolling elements eliminate gritty friction and periodic vibration, enabling ultra-smooth, quiet rotation. Low-vibration characteristics prevent system resonance and meet strict precision requirements of premium precision machinery.

Q4: How long has your factory been manufacturing bearings?
A: We have more than 30 years of professional bearing manufacturing experience, starting from deep groove ball bearing production and expanding to high-precision and new energy bearing fields.
Q5: Why do ball screw support bearings adopt nylon cages?
A: Nylon cages are specially optimized for the high-speed, low-vibration and precise operation demands of ball screw transmission systems. Made of high-toughness modified polyamide material, they feature ultra-light weight that effectively cuts down rotational inertia and centrifugal force during high-frequency reciprocating motion, enabling the bearing to sustain more stable high-speed operation than traditional metal cages. Boasting excellent self-lubricating property and smooth surface texture, nylon cages minimize friction and abrasion between rolling elements and the retainer, lowering operational heat generation and avoiding precision attenuation caused by thermal accumulation. In addition, the material delivers outstanding elastic buffering performance, which absorbs micro vibration and impact load during equipment operation to suppress running noise. It also features fine oil absorption and corrosion resistance, adapting to long-cycle lubricated working environments and resisting moisture and mild chemical erosion. With reliable structural stability within conventional operating temperature ranges, nylon cages maintain consistent guiding accuracy, effectively extending the overall service life of precision ball screw support bearings.
