Cylindrical Roller Bearings

NU220 at a glance

NU220 identifies a cylindrical roller bearing reference with 100 mm bore, 180 mm outside diameter and 34 mm overall width or height.

Width / B
34 mm

Cylindrical rollers provide radial load capacity. NU, NJ and other ring arrangements differ in axial location and displacement capability.

SELECTION CONTEXT

Match the bearing
to its duty.

NU220 belongs to the cylindrical roller bearings family. Its reference envelope is 100 mm bore, 180 mm outside diameter and 34 mm overall width or height.

Cylindrical rollers provide radial load capacity. NU, NJ and other ring arrangements differ in axial location and displacement capability.

For a manufacturing enquiry, provide the complete designation and operating conditions. Matching the dimensional envelope alone does not confirm interchangeability or equivalent performance.

Is the same size a direct replacement?

No. Matching 100 × 180 × 34 mm establishes the boundary dimensions. The full designation, tolerances, clearance, contact angle or roller arrangement, seals, cage, lubrication and performance must also be checked.

PREPARE A USEFUL ENQUIRY

Specify what the model
number leaves open.

A complete brief reduces assumptions and gives the quotation a clear technical basis.

01

Configuration

Full designation, seals or shields, accuracy, clearance, cage, material and any matched arrangement.

02

Operating duty

Radial and axial loads, speed, temperature, lubrication, fits, environment and expected service.

03

Supply requirement

Quantity, destination, packing, inspection records, drawing approval and delivery requirement.
