Bearing FAQ
What is a bearing unit?
A housing, usually cast iron, holding a ball bearing and bolted to the machine to support the shaft. The bearing turns; the housing stays put.
UCP or UCF: what is the difference?
Only the mounting. A UCP bolts to a horizontal surface with two bolts; a UCF has a square flange and bolts to a vertical face with four. The bearing inside both is the same.
How do I find the bearing size?
Measure the shaft. The last two digits of the code multiplied by 5 give that diameter: a 30 mm shaft means code 206, a 40 mm shaft means 208.
What is a deep groove ball bearing?
The most common bearing type; its code starts with 6 (6204, 6305 and so on). It takes radial load and some axial load, and suits high speeds.
2RS or ZZ: what is the difference?
Both mean sealed on both sides. 2RS has rubber seals and keeps dust and moisture out better; ZZ has metal shields, runs with less friction and suits higher speeds.
