Product Description
23030CA/W33 Double Row Spherical Roller Bearing 150x225x56mm Brass Cage W33 Oil Groove For Mining Crusher
Product Overview
- 23030CA/W33 is a double-row self-aligning spherical roller bearing with cylindrical bore, standard dimension 150*225*56 mm, manufactured from high-purity GCr15 chrome bearing steel.Equipped with precision machined solid brass cage and floating central guide ring, it stably guides two rows of symmetric spherical rollers. The inner spherical surface of outer ring enables excellent self-aligning performance to compensate shaft deflection and installation misalignment. The W33 oil groove & holes design supports uninterrupted relubriion during operation, greatly extending service life under continuous heavy alternating loads and impact loads. Widely adopted for heavy-duty rotating equipment in mineral, metallurgy, building materials industries.

FAQ
Q1: What are the exact overall dimensions?
A: Inner bore 150mm, outer diameter 225mm, width 56mm.
Q2: Difference between 23030CA/W33 and 23030CAK/W33?
A: 23030CA/W33 = straight cylindrical bore for direct shaft mounting; 23030CAK/W33 = 1:12 tapered bore, needs adapter sleeve to fix on plain shaft.
Q3: What does W33 stand for?
A: Circumferential oil groove plus three lubriion holes on outer ring for easy re-greasing.
Q4: What are the two limiting speeds?
A: Grease lubriion: 1700 rpm; Oil lubriion: 2200 rpm.
Q5: Can this bearing bear heavy axial loads?
A: Primarily designed for heavy radial loads, can withstand moderate bidirectional axial loads simultaneously.
Q6: What is the advantage of brass CA cage vs steel CC cage?
A: Brass cage has higher strength, better wear resistance, more suitable for impact, vibration and long-term continuous running conditions.
