Chrome Steel Bearing Insert, HEAVY Duty, Wider Inner Ring, Setscrew Locking,
Metric Sizes & Inch Sizes

 


UC3 type ball bearings are assembled into the various housings. The bearing inner diameter surface is of cylindircial bore type and the setscrews are used to mount to the shaft. 

The UC3 ball bearing insert can be ordered with a triple lip seal by using a suffix L3 or R3 as designation, eg: UC305L3 or UC305R3.
"L3" type seal consists of a metal cap and synthetic rubber seal, which are baked together to form a single seal. Seal lips have enough tightening allowance. In addition, the lip layers are of triple construction and outside matters, such as dust, water, etc., are shut out. This sealing system shows its outstanding function under bad conditions.

F type seals can be used in UC2, UC2...L3, CUC2 bearings, eg: UC305F or UC305F.
"F" type seal encloses a synthetic rubber washer between two metal shields. Due to the three pieces design with protective ourter  shroud, the sealing is excellent.

Plese select the bearings in the following tables. Click " CLI BEARING NO. " or " DETAILS " to check the specifications...
