Skeleton Oil Seals
TC / TB / SC / SB rotary shaft seals for pumps, gearboxes and motors.
A leak here usually means downtime, contaminated oil and a failed bearing. Tell us the shaft / bore size, speed, medium and temperature — we will match the profile and compound rather than quote from a generic table.

Where this family is used
Automotive & Transmissions
Wheel hubs, crankshafts, gearboxes and differentials — where heat, oil and shaft runout destroy a cheap seal long before the service interval.
Hydraulics & Pneumatics
Cylinders, valves and fittings that leak under pressure pulses. Correct lip geometry and compound matter more than catalogue price.
Pumps, Gearboxes & Motors
Unplanned downtime costs far more than the seal. We size by shaft diameter, speed and medium, not by a generic part number.
Agriculture & Construction
Mud, dust and shock loads demand double-lip or cassette solutions with the right hardness and abrasion resistance.
