Ultra-Slim Design for Space-Constrained Assemblies

The 16000 series includes 20 standard models from 16001 to 16020, covering bore sizes from 12 mm to 100 mm. With an exceptionally thin ring section relative to bore diameter, these bearings offer a unique combination of compactness and moderate load capacity. They are ideal for applications where housing depth is severely limited but a larger bore is required. Common uses include textile machinery, printing equipment, food processing machinery, and light industrial gearboxes where space efficiency is paramount.

Why choose the 16000 series

Characteristics, Applications & Lead Time

Bearing Characteristics

The 16000 series is built around an ultra-slim ring section for its bore size, keeping the radial envelope compact even at larger bore diameters. Across the 20 standard sizes, dynamic load ratings range from 5.10 kN to 55.0 kN, and grease-lubricated speed limits reach up to 26,000 r/min on the smallest models. Each bearing is fully inspected before shipment.

Typical Applications

This series is widely used in textile machinery, printing equipment, food processing machinery, and light industrial gearboxes — anywhere housing depth is tightly constrained but a larger bore is still required. Its slim profile makes it a strong fit wherever axial space is at a premium.

Lead Time & Minimum Order

All 20 bore sizes in the 16000 series are produced on a continuous rolling schedule. Sample orders typically ship within approximately 10 days, with no strict minimum order quantity for trial batches. Please provide the required bore size, seal type, and quantity, and we will confirm a firm delivery date.

Common questions

Frequently Asked Questions — 16000 Series

What sizes are covered in the 16000 series?

The 16000 series comprises 20 standard models from 16001 to 16020, with bore diameters from 12 mm to 106 mm, outer diameters from 28 mm to 156 mm, and widths from 7 mm to 18 mm. Complete dimensions for each model are provided in the specification table above.

Why choose an ultra-thin-section bearing instead of a standard deep groove ball bearing?

The 16000 series uses a thinner ring cross-section than a standard series bearing of the same bore, which reduces axial space and weight. The trade-off is a somewhat lower load rating and speed limit compared to a standard-width bearing of the same bore size, so it suits applications where housing depth — not maximum load — is the limiting factor.

What load capacity should I expect from this series?

Dynamic load ratings start at 5.10 kN for model 16001 and increase to 55.0 kN for model 16020. Static load ratings range from 2.40 kN to 57.0 kN. Refer to the Dynamic Cr and Static Cor columns in the table for the values corresponding to your selected bore size.

Which seal types are offered?

Every model is available in open configuration, or with ZZ metal shields, 2RZ non-contact rubber seals, or 2RS contact rubber seals. Open and ZZ/2RZ versions are better suited for higher-speed applications, while 2RS provides enhanced protection against dust and moisture with a slight reduction in maximum speed.

What's the top speed for 16000 series bearings?

Maximum speed decreases as bore size increases. The smallest models (16001 to 16003) achieve 20,000 to 26,000 r/min under grease lubrication, while the largest models (16018 to 16020) reach approximately 3,900 to 4,900 r/min. Oil lubrication can further increase the speed limit across all sizes.

Do 16000 series bearings match other manufacturers' part numbers?

Yes. The 16000 series numbering follows the ISO dimensional standard used across the bearing industry. Bore, outer diameter, and width are interchangeable with equivalent parts from SKF, NSK, NTN, FAG, or Koyo. Send us your current part number and we will confirm the cross-reference.
