This description integrates key phrases like 3300 B 2RS ZEN, double row angular contact bearing, 10x35x19 bearing, and sealed bearing for SEO relevance.

Applications & Performance

This bearing is ideal for:

• Precision mechanisms, gearboxes, compact drives

• Situations requiring effective sealing — 2RS rubber lips prevent dust and contamination infiltration

• Applications where moderate axial loads occur in both directions

• Compact installations demanding small bore bearings with good dimensional capabilities

Because of its sealed design and double row contact structure, it offers durability and adaptability in medium-duty mechanical systems.

Design & Sealing Features

Key design elements:

• Double-row angular contact: supports both radial and limited axial loads in both directions

• 2RS seal: rubber seals on both sides protect internal elements from contaminants and retain lubricant

• ZEN brand quality: recognized in various bearing catalogs, offering affordable sealed angular contact solutions

• Polyamide or metal cage (depending on variant) for reduced friction and dimensional stability

• Contact angle ~40° (typical for such bearings) to optimize axial load capacity

Technical Specifications & Installation Tips

Installation Tips:

• Clean both shaft and housing thoroughly to avoid damage to seals

• Use gentle, uniform force when installing to avoid lip deformation

• Lubricate seal lips lightly with compatible grease during installation

• Avoid high misalignment — angular contact design tolerates some offset, but not excessive

• Monitor temperature and vibration to detect early wear or seal failure

FAQ (Frequently Asked Questions)

Q: What does “2RS” stand for?
A: 2RS means the bearing has rubber seals on both sides, protecting internal components from dust, moisture, and contaminants.

Q: What loads can this bearing support?
A: It supports radial loads primarily, plus moderate axial loads in both directions—thanks to its double-row angular contact design.

Q: Is the bore truly 10 mm?
A: Yes — listed specifications confirm 10x35x19 mm dimensions.

Q: What is the contact angle?
A: Approximately 40°, characteristic of many such angular contact bearings.

Q: Can the seals be replaced?
A: No — the 2RS seals are integral to the bearing. Damage to seals typically necessitates full bearing replacement.
