Deep Groove Ball Bearings FAG 6307 -2Z

The 6307-2Z deep-groove ball bearing from FAG Wälzlager, measuring 35x80x21 mm, features cover plates on both sides to protect against coarse dirt particles.

The single-row deep groove ball bearing 6307 -2Z from FAG Wälzlager accommodates radial forces as well as axial loads in both directions. Manufactured from through-hardened standard rolling-bearing steel 100Cr6, this version has a cylindrical bore of 35 mm, an outer diameter of 80 mm and a width of 21 mm. The roller bearing complies with tolerance class P0/PN or ABEC 1 and is designed for a temperature range of -30 to +120 degrees Celsius.

What is the 6307 -2Z deep groove ball bearing suitable for in operation?

In rotating shaft bearings, the 6307-2Z deep groove ball bearing primarily accommodates combined radial and axial loads. This design is suitable for applications involving uniform rotational movements where electrical insulation is not required. With the aid of the dimensionally stable sheet steel cage, the bearing guides the rolling elements precisely along the raceway. The cylindrical outer ring, which has no groove or flange, can be fitted directly into cylindrical housing bores.

What are the features of the -2Z end shields and the standard bearing clearance?

The cover plates on both sides act as a non-contact gap seal, retaining the lubricant inside and protecting against coarse contaminants. As there is no abiding sealing lip in contact with the inner ring, no additional friction losses or frictional heat are generated. The standard radial bearing clearance is designed for regular fit conditions. Provided that no extreme temperature differences occur between the bearing rings during operation, the bearing’s internal operating clearance remains within the specified range.
