All your hubs are using TPI lu/lb seal bearing

One side (lb) is regular seal, other side (lu) is a particular seal.

We divided seal into 2 different colors. Black is regular seal, red is particular seal:

The funtion as list:

  • Non-contact type
  • Low torque
  • Limiting speed same as open type
  • Better than ZZ-type in dust proofing, poor in water proofing
  • Allowable temperature range: -25 +/- 120ºC
LU /LLU
  • Metal plate wraps synthetic rubber affixed outer ring has better sealed effect.
