Bearing Information for Common Material Handling Tire and Wheel Applications:

Single Row Radial Ball Bearing:

Front

Back

Code

NSK – DDU

Timken – PP

SKF – 2RS

NTN – LLU

Main Function, Benefit, and Concern

  • Non-Greaseable (NG)  
  • Pre-packed grease contained within rubber seals
  • Maintenance Free
  • Rubber seals have full contact on both inner and outer race
  • Rubber seals heat up and can melt down if used in high speed – leaking grease
  • Rubber seals are sensitive to chemical attack – special rubber seals are required for some environments
  • Grease cannot be refilled to replace deteriorated old grease

Where Used

  • Fork, Outrigger and Stabilizing Caster Load Wheel
  • Single direction of force (radial load) – limited thrust load capacity
  • Low-Medium Speed and NonContinuous Run
  • Clean facility, frequent washdown or wet conditions

Front

Back

Code

NSK – Z

Timken – D

SKF – Z

NTN – Z

Main Function, Benefit, and Concern

  • Greaseable (G)
  • Maintenance Required 
  • Metal shield does not make sealed contact – no heat buildup in high speed run
  • Shield does not completely prevent grease leakage but allows grease to effectively fill the bearing during maintenance
  • Shield prevents debris from entering into the bearing

Where Used

  • Fork, Outrigger and Stabilizing Caster Load Wheel
  • Single direction of force (radial load) – limited thrust load capacity
  • Long and continuous run

Front

Back

Code

NSK – DU

Timken – P

SKF – RS

NTN – LU

Main Function, Benefit, and Concern

  • Greaseable (G) – for specific design only
  • Requires extra hole in axle to release trapped air while greasing
  • Almost maintenance free when used in low speed application
  • Maintenance is required if used in high speed application due to leaking grease
  • Rubber seals are sensitive to chemical attack – special rubber seals are required for some environments

Where Used

  • Fork, Outrigger and Stabilizing Caster Load Wheel
  • Single direction of force (radial load) – limited thrust load capacity
  • Can be used in long and continuous run

  • Can be used in long and continuous run

Front

Back

Code 

 No Typical Coding Pattern

 

 

Main Function, Benefit, and Concern

  • Recommended only in Greaseable (one metal shield) configuration
  • The inner lip/race acts as a spacer on the outside of the wheel eliminating extra components and offers a quicker and easier wheel change
  • Same function as nonshouldered one shield ball bearing

Where Used

  • Same usage as non-shouldered one shield ball bearing
  • Faster wheel replacement

Single Row Cup and Cone:

Code 

 No Typical Coding Pattern

 

 

Main Function, Benefit, and Concern

  • Designed for multi-direction forces found mostly in 4th wheel casters (CL-II trucks) or drive tire
  • Maintenance Required
  • Require bearing cap to contain grease
  • Require locking element (lock nut or snap ring) to prevent the cup from separating from cone
  • Offers higher load capacity in the same size as ball bearing due to tapered roller elements which provides larger contact area

Where Used

  • Able to accept multi-directional force (radial load and thrust load)
  • CL-II Caster wheels or Drive tire

Loading External Forces:

External Force

Type

Radial Loading

Is a force perpendicular to the axis of rotation (axle), such as weight (most Load wheels.)

Thrust (Axial) Loading

A force parallel to the axis of rotation (axle), such as side impact or cornering.

Angular Loading

A combination of both radial and thrust loading resulting in an angular force acting on the bearing  (most Drive tires and CL-II Caster wheels.)
