TC is a rotary shaft oil-seal reference used when reviewing a replacement or a new shaft-sealing application. Check the sealing lip, auxiliary lip and outer case against the actual drawing or sample: profile naming can vary between suppliers. Shaft condition and lubrication must be assessed alongside dimensions before confirming a replacement.
Typical applications
- Rotary shaft sealing in motors, pumps and gearboxes
- Replacement work requiring a check of the existing lip and housing fit
What to include in an inquiry
- Provide shaft diameter, housing bore and seal width
- Show the sealing and auxiliary lip arrangement in a drawing or sample
- Specify shaft speed, lubricant and minimum and maximum temperature
- State contamination exposure, pressure and installation direction
- Confirm shaft finish, wear track and housing condition
