Precision Matters — 3304-A TN9 Nylon Cage Double Row Angular Contact Ball Bearing for Machine Tools
Machine tool operators know: a single bearing failure can halt production for days, costing thousands in downtime. When sourcing replacement bearings, the struggle to find genuine parts with reliable delivery and cross-brand compatibility often delays repairs. Mismatched precision ratings or cage materials can shorten service life, forcing earlier replacements and disrupting workflows.
Genuine SKF 3304-A TN9 Bearings, In Stock for Immediate Dispatch
As an official SKF distributor, we eliminate these frustrations. Our 3304-A TN9 Double Row Angular Contact Ball Bearing with nylon cage is stocked in our centralized inventory, ready for same-day processing. Designed specifically for machine tool precision, this bearing delivers the stability and load capacity required for high-speed spindle applications, reducing the risk of unexpected failures that derail production schedules.
Optimized Performance in Machine Tool Spindles
This Double Row Angular Contact Ball Bearing excels in high-precision rotating environments, where radial and axial loads act simultaneously. The nylon cage reduces friction and heat generation at high speeds, maintaining dimensional stability even during extended operation. Its separated design allows for easy mounting and dismounting, simplifying maintenance procedures and minimizing equipment downtime during repairs or replacements.
Technical Details That Ensure Reliable Operation
The 3304-A TN9 bearing combines critical features for machine tool performance. Its double row structure provides higher radial load capacity compared to single row designs, while the angular contact configuration accommodates axial loads in both directions. Precision ratings from P0 to P2 allow customization for applications requiring tight tolerances, such as CNC spindle systems where runout directly impacts machining accuracy. The bearing steel construction ensures durability under continuous operation, while oil and grease lubrication options support adaptability to various operating conditions.
Why Genuine SKF Bearings Reduce Total Cost of Ownership
Non-genuine bearings may offer lower upfront prices, but they often fail prematurely. A typical machine tool spindle bearing failure can cost $5,000–$15,000 in production losses alone, not counting repair parts and labor. Our genuine SKF 3304-A TN9 bearings, backed by ISO 9001 quality standards, provide consistent performance over longer service intervals, reducing the frequency of replacements and associated downtime. The nylon cage’s wear resistance further extends maintenance cycles, making genuine parts a smarter investment in the long run.
