What are the exact dimensions of this SKF ball bearing?

This ball bearing has an inside diameter of 45 mm, an outside diameter of 100 mm, and a width of 25 mm.

What does the C3 clearance designation mean?

C3 denotes a greater radial internal clearance than normal, ideal for thermal expansion and high rotational speeds.

What sealing does the 6309-Z/C3 bearing feature?

It features a single metal shield (Z) on one side, keeping the opposite side open for lubrication.

What loads can this deep groove ball bearing handle?

This single-row deep groove ball bearing accommodates both radial and axial loads in both directions.

What bore type does this SKF bearing have?

It has a cylindrical 45 mm bore designed for direct installation onto a standard straight shaft.

Smooth operation with Skf bearings

Practical benefits

Increased internal clearance: The C3 radial clearance ensures you maintain reliable performance even under elevated operating temperatures and thermal expansion.
Single metal shield protection: The non-contact steel shield protects rolling elements from debris while keeping operational friction to a minimum.
Versatile bidirectional load capacity: You support both radial and axial loads across demanding machinery drives with stable and consistent rotation.

In a nutshell

The right choise for

With the Skf 6309-Z/C3 deep groove ball bearing, you ensure dependable, low-friction operation across demanding industrial drives and rotating machinery. The increased C3 radial internal clearance prevents bearing seizure caused by thermal shaft expansion under elevated operating temperatures. Its single non-contact metal shield protects the raceways from debris without adding friction, leaving the opposite side open for straightforward relubrication. Built from durable bearing steel with a 45 mm cylindrical bore, this single-row bearing mounts directly onto standard straight shafts to handle both radial and axial loads in both directions with lasting stability.

Product description

Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.

Integral sealing prolongs bearing service life
Simple, versatile and robust design
Low friction and high-speed capability
Accommodate radial and axial loads in both directions
Require little maintenance
