Miniature Angular Contact Ball Bearings 719/4C

Miniature Angular Contact Ball Bearings 719/4C

The 719/4C is a compact angular contact ball bearing, measuring just 4mm by 11mm by 4mm. It’s designed to handle both radial and axial loads, with a 15° contact angle for smooth operation.

This bearing comes in sealed or open options, and features universal matching for easy installation. It’s available with preload for added precision, making it suitable for high-speed applications.

With a dynamic radial load capacity of 181.86 lbf, it performs well under pressure. The grease-limited speed reaches 93,000 rpm, while oil lubrication pushes it to 98,000 rpm.

Ideal for precision instruments and small machinery, this lightweight bearing (only 0.0018kg) offers reliable performance. Its ABEC-5 and ABEC-10 ratings ensure high-quality operation in demanding conditions.
