Bearing 60/22 LLU NTN

Key Features and Benefits

The LLU suffix indicates rubber seals on both sides, offering good contamination protection and retention of lubricant.

Deep‐groove design allows for radial load primarily, but also moderate axial loads in both directions.

With small size (22×44×12 mm) it is well suited for compact assemblies, shafts of 22 mm diameter and tight width constraints.

The sealed design reduces maintenance (less frequent relubrication) and helps increase bearing life in dirty or dusty environments.

Typical Applications

Small motors, gearboxes and compact drives where sealed bearing is required for reliability.

Industrial equipment where space is tight (width only 12 mm) and shaft is 22 mm.

Machines where contamination or exposure to dust/particles is expected, and double‐sealed bearing is preferred.

Replacement of older bearings in assemblies that used 22 mm bore / 44 mm OD sealed bearings.

Specification / Ordering Notes

Confirm the exact variant: “60/22 LLU” vs “60‐22 LLU” vs “60/22 LLU”. Suffixes matter: e.g., LLU seals, possibly C3 clearance, etc.

Check internal clearance: For example one listing shows “C3” (increased clearance) version: 60‐22‐LLU-C3.

Verify shaft and housing fit for the 22 mm bore and 44 mm outer diameter. Fillet and shoulder geometry must match to avoid interference.

Sealed bearings (LLU) may have slightly lower speed ratings than open bearings due to seal drag—check manufacturer datasheet for exact limiting speed.

Lubrication: Although sealed bearings come pre-lubricated, if your application runs at high speed, high temperature or has high axial loads, ensure the lubricant grade is suitable.

For sourcing: Ensure you are getting original NTN part—not a cheap copy—especially when sealed bearings are used in critical machinery.
