Eliminate Machine Tool Downtime with 3304-TN9 Double Row Angular Contact Ball Bearing

Machine tool operators know the frustration of unexpected spindle failures—costing hours of production and thousands in repairs. Many face the dilemma of choosing between overpriced original bearings with long lead times or cheap alternatives that fail prematurely. The 3304-TN9 Double Row Angular Contact Ball Bearing addresses these pain points directly, combining precision engineering with reliable supply.

Precision Engineered for Machine Tool Stability

Our 3304-TN9 Double Row Angular Contact Ball Bearing is designed to deliver consistent performance in high-speed machine tool applications. With P0 to P4 precision grades and a nylon cage (TN9) that reduces friction and heat buildup, this bearing maintains accuracy even under continuous operation. As a professional bearing manufacturer with decades of experience, we ensure each unit meets strict ISO standards, eliminating the risks of dimensional inconsistencies that plague generic alternatives.

Optimal Performance in Critical Machining Conditions

This bearing excels in scenarios requiring simultaneous radial and axial load handling—common in CNC machine spindles and precision rotary tables. The double row design provides higher rigidity compared to single row bearings, while the separated structure allows for easy mounting and dismounting during maintenance. Whether operating at high speeds or under variable loads, the 3304-TN9 maintains stable rotation, critical for achieving tight tolerance machining.

Key Technical Features That Matter

The nylon cage (TN9) is a standout feature, offering superior lubrication retention and reduced noise compared to metal cages—essential for precision machining environments where quiet operation is valued. Precision grades from P0 to P4 ensure compatibility with applications ranging from general machinery to high-precision tooling, with tighter tolerances minimizing vibration and improving surface finish quality. The bearing steel construction provides excellent durability, while the separated design simplifies installation, reducing maintenance time and labor costs.

Why Compromising on Bearings Costs More in the Long Run

Choosing non-genuine or low-quality bearings may seem cost-effective initially, but the hidden expenses add up quickly. A failed bearing can cause spindle damage, leading to repair costs 10 times the bearing price and weeks of production loss. Our 3304-TN9 meets ISO, ABMA, and DIN standards, backed by a 12-month warranty, ensuring reliable performance and reducing total cost of ownership. With strict incoming material inspections and full-process quality control, we eliminate the risks of premature failure.
