P6 P5 7030ACM Angular Contact Ball Bearing Copper Brass Cage Single Row OEM Automotive bearing

7030ACM is a high-performance single-row angular contact ball bearing engineered for industrial scenarios demanding precision, high speed, and combined load capacity. With standard dimensions of 150mm ID × 225mm OD × 35mm Width, it features a 25° contact angle (AC) and a machined cage (M) — the optimized contact angle balances radial and axial load-bearing capacity, while the high-strength cage ensures stable roller guidance at high rotational speeds . Crafted from premium GCr15 bearing steel, it undergoes precision heat treatment and raceway superfinishing, delivering low friction, minimal vibration, and long service life. The non-separable inner/outer ring design enhances structural rigidity, and optional precision grades (P5/P6) adapt to ultra-precision equipment needs, making it ideal for high-speed rotating machinery.

7030ACM Angular Contact Ball Bearing (interchangeable with bearings matching "7030ACM + 25° contact angle + 150x225x35mm size" specifications, including brand equivalents from SKF, NSK, FAG, and NTN for high-precision transmission systems )

1. Q: What does the "ACM" suffix mean in the 7030ACM model?

   A: "AC" indicates a 25° contact angle for balanced radial-axial load capacity, and "M" represents a machined cage that ensures stable roller operation at high speeds .

2. Q: Can 7030ACM bearings work with only radial loads?

   A: Yes, but they are designed for combined radial-axial loads. Pure radial loads will generate additional axial force, so paired installation (e.g., DB/DF configuration) is recommended to offset this force .

3. Q: What precision grade should I choose for a machine tool spindle?

   A: For high-precision spindles, select the P5 grade (higher precision than standard P0); P6 is suitable for general precision transmission scenarios .
