Features
- it is suitable for high radial and axial loads in one direction
- it has also an axial load carrying capacity on both sides in the X- or O-arrangement in pairs
- solid series for high loads
- accuracy grade: P4S (main dimensions at least according to ISO-tolerance class 4)
- all running tolerances are classified according to ISO-tolerance class 2
- it is designed for a high running accuracy and high speeds with maximum rigidity and operational safety
- not separable
- The mounting orientation is identifiable by the colour of the seals. The side with the higher shoulder is marked by a red seal, the opposite seal is black. This colour coding of the seals allows to see and check the mounting orientation, even when the bearing is already assembled. The installation direction is illustrated here: for illustration
- material: 100Cr6 (rolling bearing steel), phenol resin (cage)
- seal: 2RSD (2-side non contact rubber seal)
- If you need this bearing in RS design with only one seal and one open side, you can simply remove one of the two seals: to the instructions
- temperature resistance up to circa 80°C in the long run, temporarily up to circa 120°C
- You will find an explanation of the description of the bearing here: nomenclature
- comparable with 7205AC-2RZ TA/P4S (CSC), 7205A5V1V (NSK), S7205ACD/P4A (SKF)
